ok. I'm done with the shock process and passed the oclt. Here are my results:
fc 13, cc .5, ta 190, ph 7.5, cya 50
Do i need to start lowering TA? from what i have read the best way to do that is drop ph to 7 then raise ph with aeration? i have a slide. is this a good way to do it? even if i point my returns up they barely break the surface. will this work or do i need to make an aerator??
