HBdirtbag Posted May 23, 2018 Report Share Posted May 23, 2018 Hey guys, i need to put a surface skimmer in my 55G tank. It's a 24" tall tank and gets some scum on the surface during the day. I've been using an eheim 350 like pictured below. Every few days I empty shrimp out of it (usually 5-15 shrimp, have only found one death), but would like to come up with something that would prevent the shrimp from entering. I've tried to stack it with sponge inside, but it weighs down the tube to much so that it can't float. would be curious what other people are using as a solution. I've got this unit on my 120P Fish tank, thinking about moving it over as it's clear and I can see inside, but it's not that powerful.

MNCarpenter Posted May 29, 2018 Report Share Posted May 29, 2018 What about wrapping window screen around it? Not sure if that would still let the scum through. Or I found putting an airstone about 4 inches below the surface cleared up the film in my IM nuvo fusion after I placed a sponge over my overflow to keep shrimp in. Still looking for a better option as a flat screen sucks shrimp tight to it and I can't find a good mesh guard just plastic fish savers. That's off topic but the added surface agitation cleared it right up. I was using an open air line at first but it clogs up fast. U mite as well just add a small DBL sponge filter for added bio surface area. Quote Link to comment Share on other sites More sharing options...
HBdirtbag Posted May 29, 2018 Author Report Share Posted May 29, 2018 i ended up finding some very light weight mesh material my daughter brought home from school. It's light enough to not hold the plunger below the surface and still let it float. I did catch 2 amano's in it after 48 hours, but I blame them for it...dumb asses probably climbed over the screen.

chappy6107 Posted May 30, 2018 Report Share Posted May 30, 2018 are you trying to keep the surface from being agitated? otherwise the more surface movement you have the less surface scum you will have. Quote Link to comment Share on other sites More sharing options...
HBdirtbag Posted June 5, 2018 Author Report Share Posted June 5, 2018 the tank runs Co2, so i am not looking for a bunch of agitation. That said....this tank sprung a leak on me over teh weekend...... so no worries anymore as I tore it down...good news....don't think I lost any shrimp....pulled out about 300+ Quote Link to comment Share on other sites More sharing options...
