So I have this stuff all over my HOB overflow and return tube and on the roots of my mangroves but no where else. I noticed that my overflow wasn’t flowing as usual and as I started to investigate i realized it was all over. Even hairs of it shooting out of my return nozzle. Any help is greatly appreciated.
