T Dawg Posted March 3, 2009 Report Share Posted March 3, 2009 If well washed, is it safe to use stainless steel nuts on the plastic tubs to hold them down? Our air stones keep drifting off the bottom and the tubing keps workings its way above the gravel. Any other sugestions to keep everything on the bottom?

You can do that or get some suction cups made for airline and stick it down. John Quote Link to comment Share on other sites More sharing options...
Baos Posted March 4, 2009 Report Share Posted March 4, 2009 When I used airlines in my tank I held them down with some fist sized rocks, and buried the rock under the substrate. I believed I picked up the rocks from a $5 bag at pjs while they were clearing old stock. Quote Link to comment Share on other sites More sharing options...

Try switching to a bubble curtain or a disk and they'll definately stay down. Quote Link to comment Share on other sites More sharing options...
