I recently set up a tank (20h) and I have had it running for about two weeks now and can not seem to stabalize the Ph. It is really high, about 7.5-8.0 (my test kit only reads up to 7.6) What should I do to lower the level before putting fish in it? I would like to have the level between 6.8 and 7.2. The lfs told me that this level is ideal for piranah's. The lfs i usually go to just got in about 50 baby piranah's( 1/2 inch max and I would like to get four them. I have been looking for them this small. What can I do to lower the Ph level, Fast. Thanks for all the help you guys offer.
