ahh so annoying, I had a whole essay on a problem and then I doubled clicked and lost the lot. Somtimes computers drive me banana's!!
Anyway, here's my problem. I seem to be having the opposite problem to that described in this thread ie I can't seem to keep my pH from falling. Even without the CO2 system which I have, the PH seems to fall slowly over time. Now my water is very soft in this NY suburb district. Not so bad for my discus or house plumbing but it is annoying nontheless. My water has a low KH values and has been known to cause inbalances in the PH levels in the past. To rememdy this issue I have added sodium bicarbs before to increase both the KH and PH values. This works but it never seems to keep the values up. What KH values should my tank be at ? Any typical values? Should I be dosing with some sort of KH solution? My water has gotten down to PH 5.3 and KH 1.0. Right now its about 6.0 (a 0.2 drop over two days), KH unknown right now
I have a planted tank, eco-complete substrate, a large piece of driftwood covered in BBA that I can't seem to get rid off (the CO2 won't come on due to the low PH to help comabt this), eheim 2215 for a 46 gal tank. Bioload seems reasonable. I have fast growing plants like duckweed that I suspect, drain a lot of nutrients from the tank. Could these be a potential problem with altering the KH values? I have 96W light on for 10 hours a day.
My current stragegy has involved adding crushed coral to the filter media to try and increase the hardness of the water. So far this method has paid no dividends. I can continue to dose with baking soda but this doesn't seem like a good long term strategy. Does anyone have any thoughts on this? I could use some experience on this one...
