Does anybody know what this is and how to get rid of it I think its a flow issue. I replaced pump I have a scwd getting good flow but now it blows breaker once in awhile. and this stuff come right back as soon a water sits for abit!!
but turn off all your currents, your lights, everything. they will gather near the top and you can siphon the crap out of them. then does the tank with flatworm exit, do the recommended water changes, and repeat until gone.
