Iāve been trying to work out the issue with the pH of my aquarium water for some time now,but I still canāt work it out.
The pH of the tank dropped to 6,and this happened quite suddenly after changing the gravel out and replacing it with sand.Since then (months ago) the pH has been dropping from 6.4 to 6 a couple of days after a water change.The cycle goes something like this,I test the water in the tank and itās 6,I do a 75% water change and it lifts to 6.4,but then it drops to 6 within 2 days.Itās a total mystery and itās happening again,I just canāt work it out.Iāve blamed the sand and the wood,but Iāve had more wood in the tank in the past and the pH held at 7.
I did have gravel back then.It seems to be since I added purely sand,but I only have around a half inch of sand as substrate.
Adding new fish is problematic,Iāve tried and they canāt cope with being put in water with such a low pH,unless they have come from water with the same pH,which I doubt very much.
Anyone any ideas what could be causing this,as itās pickled my brain for long enough.
Can sand cause this?
Can wood cause this?
Can a strong flow cause this?
Can any filter media cause this?
The only other thing Iāve changed is the power head and filter media,which is now biohome media that is āsupposedlyā able to help reduce nitrates and actually does seem to help a bit.The power head produces a strong flow.
I now have to change my water change routine to 25% daily in order to maintain a stable pH.
This one is a total mystery and although I can google info,Iād rather see what answers could be offered by the experts on here.
