I've been looking for some ph up and I have come across ph up for pools and for fish tanks. Are both of these ok to use or is one i should stay away from...?
Stick with the fish tank formula. It might be OK to use the pool one, IDK, but fish tank definitely is OK.
I bought a quart of pH down and a pint of pH up at a hydro store 5-6 years ago, but when I run out I'll just buy some more off the intermet.
pool ph up may work....sually if its safe for humans its ok for plants....pool ph down is hydrochloric acid (muratic acid) is ok to use for plants
