How can I get the PH level to stay down in my aquarium?I add the drops and nothing works?
by Aquaboy on Monday, March 15th, 2010 | 2 Comments
I have a 30 gallon tank 1 large angel fish and 1 small angel and a very small rainbow shark. I bought the PH Regulator powder and according to my water tests – it is still high. I do a water change every 1-2 weeks and re-add the drops and powder to adjust and lower it but it seems the same. Can anyone give me some suggestions? I successfully am keeping the Angel fish alive but want to keep it that way
I have good tank filters – so it can’t be that….HELP!

I breed angel fish for a living what is your PH messing with PH causes more problems than if you just leave it alone
my ph is higher than what it should be but the key is stable PH my PH stays the same and never fluctuates
What is your PH in your tank ?
Chemicals should be used at a last resort. There will be too much fluctuation with the pH if you use those drops, which is definitely not healthy for the fish.
The best way to lower pH is to add driftwood/bogwood and peat moss. I must tell you though, I don’t recommend messing with it at all if the fish seem happy and are thriving, but it’s your choice. The peat moss you’ll have to keep replacing, but it really does help in lowering the pH. I don’t recommend adding both at once. Try the peat moss first, give it a few days, and see how your pH is. Then add the drift/bogwood if you’re interested. Keep in mind that it probably will dye your water a light yellow which isn’t harmful to your fish.
The 30g tank is suitable for the small angelfish and rainbow shark for a period of time, however depending on how large the “large angel fish” is, he’ll probably need a larger tank. Angelfish can grow up to 8″ tall, so nothing less than a 40g tall tank is recommended for each.
You may also be running into some aggression issues with the rainbow shark and the angelfish. Rainbow sharks are semi-aggressive and angelfish are docile. You may have to remove them.
