My ph is about 3.6 points too high. What do fish do if the ph is wrong? What signs do they show? Are they distressed or really sick looking? My fish dont look that way but there could be something I'm overlooking.
Is ph super important and if it is can someone reccomend ways to lower it? U heard peet moss is good, but how do you use it?
WOW that is really high. When you tested your tap did you let sit out for 24hrs, stirring it occasionally & then test it? Or is the 9 from your tank? My understanding is that to get a true Ph from your tap you need to do the 24hr thing. As for the fish, it is better to have a steady Ph than to try to adjust it as that can cause big fluctuations & cause more harm than good. Some of the ways people lower their tank Ph naturally is as you asked about, peet. They put it in a nylon or filter bag & place it in with their filter. Real driftwood, crushed coral I believe also help. With the peet add a little, check your Ph 24hrs later, if not low enough add some more & keep going until you get it where you want it.
