What kind of sealant???

[quote author=hottielover14 link=board=Refugium;num=1083630120;start=0#6 date=05/28/04 at 20:33:53]i'm using  this PVC cement by Master Plumber to connect all my piping to each other. It has a very strong smell and I'm not sure if it's toxic to my reef tank. I don't know of any other PVC cements that aren't toxic.[/quote]

 

Home Depot has the aquarium safe sealant for $3.50 for a small tube. Big Al's has the same stuff for $8.00 a tube for the 10oz (caulking gun size) tube. Al claims this is the stuff with which they build aquariums. I have used it to build a small terrarium. It is very strong and undeniably not toxic. The other silicones I am personally very leary of because of the ingredients. They all have some sort of setting chemical (acetic or otherwise) and definitely have to be allowed to cure.
