I think i need to add another PH
to my tank for better movement. I currently have a 30 gal
. I have a fluval 204 and a cpr bak pak moving the water around. I should probably get another PH
huh? I can put one on the opposite side of the tank pointing in the direction of the fluval, right? Is having the currents cris crossing ok? Also...what size PH
should i get? I was thinking of getting a maxi jet....but i would like to get the smallest one i can. Also, i am starting to get some coralline growing on my rocks....will blowing the water over the rocks help with its growth??? Thanks for any help!
