Nvladik, I think that's pretty cool, I mean anything that exports this stuff has to be helping right? BTW, several people have mentioned using air line and a hard air tube as a way to remove dino from the sand bed which seems fairly minuscule to me, not to mention "labor intense" but today I ran in a Petco to look for some hard tube. Well they didn't have any but I did purchase a small gravel vacuum that came with a priming bulb and not least important it had a bucket clip to hold the hose! This got me to thinking I clipped the hose clip so it holds the discharge right into the screen sock on my drain to sump, I vacuum all the sand bed clean, got the big nasty in the sock, return pump kept right up and circulation never stopped. Now if I can just figure how to attach a small brush to the vacuum tube to clean the rocks of dino clusters while I vacuum them out, I can make some real export headway. Still fighting dino!
