i am cycling my 75g tank. i switched to pool filter sand i picked up at ace. the next day my PH went from 8.0 to 8.4.
i tried putting some of the PFS in a tupperware with some water i tested before adding. the next day the water with the sand had a ph of 8.2 while the control water was tested at 8.0.
it seems like the PFS i bought is definetly increasing my ph. has anyone heard of this before?
i thought PFS wasnt suppose to mess with waters chemistry.
anyhow i need to get my ph down before i add fish. any ideas?
i dont want to have to use ph down ever time i do a water change and my water is very soft so stability may be an issue.
i am thinking maybe i can add something to the tank or filters that can gradually bring down my ph.
ideally i would like to get down to 7.0 or so. water from my tap is around 8.0. water in my 75g tank with sand around 8.4.
