So I've added coral to my freshwater tank in attempts to raise my ph. I have put chunks of coral in my tank. They are not "crushed " .
So I know the coral works from where I tested it in a container of fish tank water. It raised the ph there after sitting for a couple of days. I believe the ph has come up some considering the yellow that used to show after a ph test was pale faint yellow. Now it's a dark yellow, so logic would says its come up some but not high enough.
So my question is does it have to be crushed? Would it not work with just chunks in the tank?
My ph from the tap is a consistent 6.8-7.0 however even with pwc the ph still stays at atleast 6.0. I use prime water conditioner. it specifically states on the bottle that it does NOT effect ph.
So I'm at a loss here. I've also read that sea shells work as well. Does it have to be a certain type of sea shells?
Some ph help would be greatly appreciated..
Thanks,
Liz
