The bubbles appear in the morning when the light comes on. Ive been trying to get my nitrate levels down, been doing more water changes, changed salt type to coral pro salt, installed a psk-75 in a 55 gal hex tank. I had another protein skimmer but trying the psk-75.
Right now both are running till i sort out this nitrate issue.
Tanks been up for 5 + years, im trying to transitioni to a reef tank., I am going to a RODI water that I will be making myself. I just got TDS monitor and my number is high (400) from tap water, gettin a rodi thing.
flow I just got a new power head too, right now i have two running so not sure flow is the issue...after more reading it may be micro bubbles from the skimmer breaking in? but this started around the time i started to pick up my water changes and the new salt about a month ago, new skimmer is 5 days old.
