Thank you. I am currently getting 350 PAR at highest points, 250 across most everwhere else in the scape so I will put the new Chernobyl up high and infront of the flow as much as possible.In my 6ft 125 i run 2 mp40s at 100% and have a little gyre in the middle at 80% pulse.
I do run the aneneme guards and they do cut down on flow compared to OEM. I neglected cleaning my powerheads recently, the next day my pH was up .04 from the day before. Not sure if that was air exchange related or coral consuming more.
My understanding spaths are super shallow water coral and PAR and flow are necessary. Apparently hard coral to keep alive/not turn brown.
