One of my rummies jumped out today after I did a 40% water change yesterday. There are 9 left in this 25 gallon. I assume its the ph swing. How long should I leave out some water for a water change so the ph doesn't swing too much. I was also contemplating getting an ro unit from spectrapure for less than $200.
Also plants not growing as well as I'd like considering I just upgraded to co2 and have the drop checker in the green for the entire 8 photoperiod. Its been about 3 weeks since set up but there isn't much growth with the hc and hairgrass and I am running 2 24w t5hos. Ph is at 7 or lower, gh at 8, kh at 3. Also already seeing algae on display rocks.... using ada aqua soil, dosing traces, excel, mono potassium phosphate on ei. Any thoughts? I was thinking pressurized co2 was going to be enough to make me happy,
