Hi, I recently started having some major problems with my 10 gallon tank and I don't know what to do with it anymore. I have another 20 gallon tank and a 5 gallon and those ones haven't ever had a problem like this. In my 10 gallon I have 2 crayfish and a BN pleco and usually the BN pleco keeps the glass clean but now there's brown algae on all sides of the tank. Also, there's some major bug problems. I've got some worms that are about an inch long going across the glass then there's little red worms that live in clear tubes (their head is the only thing that ever comes out of it), then I've also got some green gnat looking bugs that fly out of my tank every time I open the lid. The only bugs that I'm really worried about are the ones that live in the see through tubes because they've attached themselves to my crayfish and I'm not sure if that could end up being a problem or not. I've been doing 2-3 50% water changes in the tank that's been having all of the problems but they don't seem to be helping too much. It helps the day I do the water change then overnight it seems like all the bugs are back. And its kind of hard to vacuum out the worms because they're latched onto the glass and the crayfish and the substrate and everything else in the tank.
