Syphon red slime through filter sock, mistake?


New member
I am having a red slime algae problem with my 150g tank, I have been doing lots of water change but need to syphon to keep it from over taking corals. Would I be spreading the algae further by syphoning it through a filter sock back into the sump?

Not a bad idea if you end up removing most of it in the sock. Keep in mind that it loves low flow areas, so don't siphon into the sump if it's going to get a foothold there and start spreading faster.
