Thanks Guys.

I put the 180 mainly so taht when I am refilling I don't get media down the tube. But I guess just cover it at that time and things work fine..

Thanks.. Once I get the new stand finished I guess this is my next little project.. [img]images/smiles/icon_wink.gif[/img] And then we are making a new neilsen reactor.. [img]images/smiles/icon_smile.gif[/img]
