Hey all, I posted about this a little while ago but wasn't very clear with what I needed I guess. I'm looking for ideas from you all that may have large planted tanks or spiny eels with in tank pvc overflows. The caps I had on mine fit pretty snugly but don't really work for what I want. I've tried keeping two large fire eels and every time they find a way under the caps and into the sump. Also, plant matter that gets dislodged by my pump current clogs up the drain covers and then not enough water gets to the pump--making it run a little dry. The covers I have now are bathtub drain covers from home depot. What do you all do to keep your eels in your tank and water in your sump? pics or products would be greatly appreciated...oh and something that keeps the siphon pretty quiet too lol Thanks.
