control PH for Discus with CO2

[Silly me]

I currently have a heavy planted tank with my discus but I would like to add three more, so this moring I setup my hospital tank and was hopeing to get them tonight..

so I added some water from the main tank
but I add PH down to the water changer ( 100gallon bucket outside ) to get a PH value of 6.6


but the PH in my main tank is kept at 6.6 with a PH valve setup from my CO2 bottle. Nothing in my hospital tank will keep the PH anywhere.. but its a 30 gallon so a 10 gallon waterchage every two days will sort that ( the lowest amount my waterchanger have )

Could I just setup a tank add CO2 to the water changer to drop the PH with CO2?
this would save me a packet, three 10kg bottles CO2 will cost me less that the PH down I buy in a month. and currently 10kg CO2 last 4 -6 months

Why do you want you ph to be low? i have discus and ive been raising them in 7.8 ph and they have even successfully breed in that too. The thing with discus is constant ph, i found that it was more trouble trying to keep my ph low, so i slowly acclimated them to my tap waters ph (i age my tap water cause it starts at ph of 7 and over night raises to 7.8 ). they are doing great, im spending less money cause i dont even use dechlorinators anymore cause chlorine dissapates in 24 hours. you should go to www.simplydiscus.com/forum its the best website out there for discus IMHO.

It is ok to do that if your local water supply only contains chlorine and not chloramine.

Water companies are increasingly using the later and it dies not dissapate, it has to be treated.


Interested that you keep them at 7.8, my water 7.4, but the co2 lowers it a little more. Perhaps I can keep them too??

I did look into it earlewir in the year but most people said I should really be usinfg RO water...pretty expensive kit.

well, my tap does have chloramines, but that also disapates in...48 hours with no agitation, it goes out quickly with plenty of agitation. Only reason i see to use an R/o unit is if you have very bad water, or very hard water. If you have really hard water an r/o unit will let you use that water for breeding...otherwise...waste of money IMO

In less you have really bad water you shouldnt need an R/O inless you want to breed. IMO a stable pH is a good pH so I wouldnt try changing it all the time because that will stress the fish out alot.
