There are no hard and fast rules about keeping discus in soft or hard water. However, they thrive in water which has a PH range of 6.5 to 7.5, a GH (general hardness) in the range 3º - 10º and a KH (carbonate hardness) of between 1º and 6º.

Water changes are the key to success.

Water with the same parameters & temperature as the tank water should be used to avoid stressing the fish. Water should also be stored for 24 hours prior to being used and be treated with a de-chlorinator. Water changes really are the key to keeping healthy discus.

Asian breeders change up to 95% at any one time (but their water is near perfect!!)

Is My Water Too Hard For Discus? by Carol Roberts

Probably not!  Juvenile discus actually grow faster in moderately hard water.  Most places in North America have water suitable for growing out juvenile discus. 

In the wild, discus live in very soft (low GH) and acidic (low pH) water.  Domestic discus can be kept in soft to moderately hard water (GH 3 to GH 14). Most discus are raised in a pH above 7 and many hobbyists report success with a pH of 8.5 or higher. 

Discus do need water with stable parameters. They do not like large drops in pH.  If you have moderately hard water or well water you may need to “age” your water to stabilize the pH.  You can age your water by aerating or agitating it for several hours to release dissolved carbon dioxide. Aged means the pH has reached equilibrium.

When considering pH, you should know which ph you will maintain for your aquarium. Like discus fish loves to live in a high ph level,7.0 may be the optimal pH level. the same fish will likely thrive at a constant level anywhere between 6.6 and 7.4. for their breeding you should keep 6-6.5 ph level. For a marine aquarium, you should keep more than 7 ph level. In other words, a constant pH of 6.6 is better than a pH value which fluctuates between 6.6 and 7.0, even for a fish which prefers a 7.0 reading

PH
Display – 6.5 – 7.5
Breeding – 5.5 – 6.5
Grow-Out – 6.8 – 7.5

Hardness:
Display – 10–15 GH, 5-8 KH
Breeding – 1-4 GH, 0-1 KH
Growing-Out – 8-15 GH, 5-8KH

I would avoid buffers/additives when keeping discus; unless, they exceed the ranges above. Discus love good clean consistent water quality, so be careful of even slight fluctuations when performing water changes.

Note: Some PH buffers increase phosphates in your water and promote algae growth.

Hope this helps!

Discus are very particular about pH. Keep your pH below 7 and above 5.5. The ideal pH for discus is 6. At pH levels above 7, discus are stressed. Below 5.5, the pH is inclined to plunge rapidly, so I find 6 to be comfortable for both the fish and the fishkeeper.

It seems that one of the most common questions that I see in the Water Works section is on how to modify pH. For the most part there is absolutely no need to change your pH. 

If growing out baby or juvenile discus, there is no need to change it unless it is acid or basic enough to melt them. 

If you are trying to breed adults, you might have to modify pH to induce them to spawn but probably not! 

I make RO units and help people with water questions very frequently. I have talked to people that have tap water with a wide range of pH values and hardness from soft to rock hard. People with pH of 8.5 report the same sucess with raising and keeping discus as people with 6.0 out of the tap. I personally keep all my discus (except my breeding pair) at a pH of 7.8 with GH of 8 and KH of 6. The breeding pair is at 7.2 due to the addition of RO water that I use to lower TDS. 

There is no magic pH value or TDS reading. Consistency in the quality and parameters is more important than anyone's arbitrary set values for water chemistry. There is no absolutely exact value for raising and keeping discus. Giving them consistent pH of 8.0 is better than bouncing your water's pH around with chemicals and additives trying to get that magical 6.8. It's a lot cheaper too, both in chemicals and the health of your fish. 

If your tap water pH changes with aging, age your water and do your water changes. If it stays the same and high, just use it as is and do your water changes. Your fish will be happier in the long run. 

I personally killed quite a few angelfish and assorted tropicals (dozens in fact) when I was starting out because a local fish store employee told me I had to have a pH of 7.0 for a community tank. So I bought the pH Up and pH Down and the Proper 7.0. I added it and the pH went all over the place. I couldn't figure out why my fish died after I did a water change. It's a miracle I'm still into aquariums it was so frustrating. But a good store owner (trying to sell me discus, in fact) told me that was crap and my fish stopped dying almost immediately. So here I am today, nine tanks with more on the way just waiting for my first pair to get it right (fourth spawn on the 16th! Not yet, but they keep trying!) 

A good rule of thumb: If you can drink your tap water your fish will be fine in it. 

http://www.simplydiscus.com/library/water_...eneral/ph.shtml

pH is a water parameter measuring how acidic, neutral or alkaline the water is. 7.0 is neutral, lower than 7 is acidic, higher than 7 is alkaline. PH stability is affected by the amount of buffers (KH, carbonates) that are in the water. 

An acidic pH can change ammonia, NH3, into nontoxic ammonium, NH4. Acidic pH can also inhibit bacteria. 

Lowering the pH can be accomplished through the use of acids or peat moss. The higher the buffering of the water, the more difficult it is to lower the pH. When adding acid, usually if there is any buffering in the water, the pH will "bounce" back up after several hours. If there is not enough buffering the pH could "crash" (drop rapidly and far). Adjusting and aging the water before adding to the aquarium is best for stability to the aquarium environment. Aging the water with aeration for 24 hours will get rid of CO2 (CO2 is carbonic acid) in the water and the pH will rise (if it is unstable pH).

JEFF'S RULES
Don't worry about your pH!!
Pretty simple ... huh. I must be out of my mind ...

I've been raising Discus in tab water (unaltered chemically) for over 12 years ... the pH out of my tap is 9.5. Yep, 9.5. Now, my water is soft, so the pH actually drops to the high 7's once it mixes with the tank water. But I do 95% water changes occasionally with straight tap and I haven't had problems.

I used to use Seachems Discus Buffer to drop pH to 6/6.5 because all the literature said I had to have acid water. Instead, the chemicals actually caused problems with the breeding of my angels and discus (eggs calcify) ... when I stopped the problems went away.

I don't advocate chemicals to alter pH ... here's why
Costly
a lot of work
Dangerous ... if you don't mix the chemicals correctly, you could have massive pH swings, which I've seen 1st hand wipe out tanks of fish ... stress related illnesses develop such as ich

In my opinion, STABILITY is far more important to maintaining healthy fish than trying to achieve "the ideal pH". 

Am I saying that Discus don't do better in soft, acid water? Absolutely not. IF one could easily, cheaply, and safely maintain a low pH, you should do this. What I am saying, though, is not to worry about pH ... domestic discus have seemed to aclimated themselves to harder, less acid water very well ... there are lot's of breeders and sellers raising discus in straight tap water which is not acid.

Small fish should be kept in groups (the larger the better) older fish can be kept singly or in pairs, groups in large tanks. Mature fish prefer soft acidic water (wild fish will thrive in pH down to 4.5) while young fish need slightly hard water for proper growth. Most tank bred Discus will accept a pH up to 7.6 after carfeful acclimatisation. At any pH above 7, extra special care to eliminate/prevent ammonia is crucial. Water must be warm, 86F/30C is ideal, with gentle water flow. Provide plenty of cover with bogwood, roots and carefully chosen plants that can tolerate heat.

Adjust the pH of your water: The discus fish likes water with a pH between 6 and 7.

http://www.buzzle.com/articles/discus-fish-care.html

Water pH: The softened water will adjust the pH to the desired level easily. The recommended pH for fish should be between 6.5-7.5 for display purposes, and between 5.5-6.5 for breeding purposes. Adding peat is a great way to lower the pH gradually, however, it's advisable to have someone well versed with water chemistry to do the job.

While breeding discus, many breeders end up losing a lot of their fry. One of the main reasons for this is young inexperienced parent fish. Another reason is the pH level. For breeding discus, the ideal pH level would range from 6.0 to 6.5, and an 86oF temperature would be perfect.

"Discus Fish Farm" is a website for all discus hobbyists. We are discus breeders in the USA. We breed and raise our discus fish in tap water with a hardness of 100 ppm - 200 ppm. The pH is adjusted to 6.0 - 7.0. 

http://ctdiscus.com/A_Basic_Guide_to_Discus.html

Water: 
What I will write here will conflict with much of the older works on Discus. Discus evolved in waters that are very soft, and acidic. Because of this they earned a reputation for needing to be kept in that water. Cited often is water in the range of 5.5-6.8 pH, and low TDS (total dissolved solids). This may have been the case in the past, and is certainly beneficial for discus. However, what many hobbyists and breeders, including the Author, have found is that although Discus do well in waters with these parameters, domestic discus are remarkably adaptable in their water requirements. This may be the result of generations of captive breeding and selection, no one can say for sure but it has made keeping these wonderful fish much easier. Young discus will grow fine in water that is between pH 7.0 and 8.0, with some raising them in water that is higher than pH 8.0. This water can have a high kH and high gH and it will still be suitable for any non-breeding discus. Discus that are to be bred will spawn more readily in the softer waters, and lower pHs. Many have noted decreases in egg hatch rates as the waters hardness goes up. To compensate for this, breeders not blessed with soft water make use of Reverse Osmosis water filters, De-ionized water, or Peat filtration. These allow for the removal of the minerals, and subsequent softening of the water. With so many ways to manipulate ones water with a little research, keeping and breeding  discus has  never  been easier.

Discus of all kinds, wild and domestic do best in water of a pH between 6 and 7. Best in many ways not to try to match any lower value than 6.0, as most ways this is achieved leave little buffering capacity and a "slippery slope" to chemistry problems. Is your water of "moderate" hardness (up to 10 degrees of GH) right out of the tap and a pH between 6-7? Fine. I would store it in a container, heated, aerated and ready for use on an ongoing basis somewhere near the discus system. If it were of higher pH, too hard, you would do well to consider "blending" it with water of lower pH and hardness (perhaps made at home via an RO or DI device)… maybe you could boil some peat moss, place this in a filter and run the new water through it for a few days. In extreme cases of very hard, alkaline water you may have to resort to chemical treatment.

As long as the pH is on the acid side of neutral, between pH 6.0 and pH 7.0, your Discus will be quite happy.

Εγω δεν θα παρω θεση στην ερωτηση του φιλου Geosid για το τι pH πρεπει να εχουν οι δισκοι για τον απλουστατο λογο οτι δεν θεωρω οτι εχω οργανο αξιοπιστο για να μου δωσει τιμες ακριβεις ωστε να μπορω να μιλησω με νουμερα (οργανα αξιοπιστα θεωρω καποια με 4ψηφιες τιμες). Προφανως οι φιλοι απο τα φορα του εξωτερικου εχουν οργανα ακριβειας αλλιως για μενα ολα ειναι στον αερα.

Τα ηλεκτρονικα οργανα που χρησιμοποιω εγω τα εχω για να μπορω να εντοπισω με μια γρηγορη ματια τυχον μεγαλες αυξομειωσεις στην καθημερινη παρακολουθηση των ενυδρειων μου και τιποτε αλλο.

Το τι pH θελουν οι δισκοι θα σας το δειξουν απο μονοι τους αν δεν τους αρεσει.
