90 gallon tank, co2 reactor, sump system. I recently moved from gravel to aquasoil. Before the switch my pH was a 7.2 no CO2 and 6.0 during lighting period. I am using a ph controller, and carbon doser. After I completely rescaped the tank with the aqua soil my pH was at 5.4!!!!!! too low for the controller to even turn on. I added some baking soda and that brought the pH up to about 6.4 allowing the controller to turn on. It has been 3 days since the rescape, and it seems like the ph is flucuating dramatically. There is never enough CO2 in my reactor... Meaning the pH is off somehow. PLEASE HELP ME!!!! I cant seem to figure out how to stabilize my pH back to what it was before i put the aquasoil back in. I put baking soda in, but ears this is only temporary...
