Problems with soft water

[xeronimox]

Any time i start to use soft revers osmose water, my fish become dark, and they stop to eat.
I use always to age the water with adding extract of peat, the parameters of the water are not extreme.
This means:
Gh 5
Kh 1
Ph 7,2
ms 100 or 65
??? ??? ??? ???
Please Help

Does the ph stay stable? Are you mixing the RO water with any other water or minerals?

Its a pretty low kh which stabalizes ph. Set some of the intended mix water in a bucket, check the ph, then after 24hrs with aeration check the ph again and see if it remains stable.

I agree with Ardan, KH of 1 is pretty low, especially when you're using it with soft RO water. Are you measuring the Ph before you put it in the tank, or a day after? Soft low KH water is very unstable and lends itself to sudden and extreme ph crashes.. you might want to consider adding a ph buffer and even bringing the GH up some unless you're breeding.. I found that when I first started using RO and didn't have the GH and KH stabilized correctly I had constant ph crashes even with daily water changes... this also leads to continuous ph fluctuations which isn't good for the health of the fish..

Ciao Ardan,
I use to age the water with strong pump movement the Ph fluctuates up to 7,7 .
In the fish thank the Ph is 7,4, i don't see a big difference in the ph range, that could create the problem.

Thanks for yor patient

Does your tap water contain chloramines? If so, are you using something to neutralize ammonia?

Yes jeep,
my tape water at the source contains cloramin. Are possible after i run the water trougt the "coal + 2micron prefilter + osmosis" i can have problems with the cloramin ???, considering the finaly water are 60ms.


Thanks
