It’s been a while since posting but all’s been going well till this little problem has come up over the last 2 weeks. This is the second sock change that I have had this happen and I was wondering what is causing this problem. On inspection of the overflow pipe running in to the sock I also found the rust colour slim coating the pipe as well as in other pipes in the protein skimmer the phos reactor and the return pump intake. All of the places it is growing are high flow areas.
It is not at all in the tank it self only in the no light areas and pipes.
Is this a form of cyno? Or some other algae.
The water parameters are as follows
So the nitrate is high but that’s the only one out of whack and when the first sock was red the nitrates at that time were only 5ppm.
