Caper Posted March 18, 2009 Report Share Posted March 18, 2009 Considering how heavy rocks can be, how do you determine how much/many rocks your tank will safely hold??? How do you know if silicone is aquarium safe? Are you folks buying it in a pet store?? Thanks, Caper Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted March 18, 2009 Report Share Posted March 18, 2009 You buy the product that is for glueing glass and has suitable for aquariums on the label. I buy Selleys because it is the cheapest where I shop but there will be others. It will be cheaper in a cartridge than a tube and also from a hardware store rather than a pet shop.

livingart Posted March 18, 2009 Report Share Posted March 18, 2009 so long as your base glass is supported evenly and the rocks are put in gently you could probably fill the tank that is so long as the stand will support the weight some people put thin polystyrene under large rocks as an extra precaution make sure rocks are not able to slip and jar the glass over here silicone is available in a hardware store, should say safe for aquarium use on the tube Quote Link to comment Share on other sites More sharing options...
Ira Posted March 18, 2009 Report Share Posted March 18, 2009 Livingart, many(If not most, I'm not sure on the exact number) tanks in north america don't have the base supported at all. The whole tank is just supported around the edge. You should see how violently they'll argue with you that if you have a tank's entire base supported that it will break. :roll: Quote Link to comment Share on other sites More sharing options...

Caper Posted March 19, 2009 Author Report Share Posted March 19, 2009 livingart, Ira...what do you mean by the base not being supported :oops: :oops: Sorry, I don't understand what you mean. Thanks for the site Zev, me leave here...absolutely NOT. You folks are my anchors in the aquarium world plus you're my friends So, nope, not getting rid of me We do have a Rona store here, well used to be called something else but now Rona so I'll have to check it out.

Zev Posted March 19, 2009 Report Share Posted March 19, 2009 What they mean is that the entire base of the aquarium sits flat on the tank stand of table it is sitting on - the whole glass sheet, not just a frame around the edges of the tank where the sides join.

Caper Posted March 25, 2009 Author Report Share Posted March 25, 2009 So all my tanks have a metal frame on the top and bottom. So it's not just glass sitting on stand. Does this make a difference in the amount of rocks or if you can use rocks at all??? I'm just planning on a few rocks if I can get some once the weather gets warmer and I head to the beach. Would like to try and silicone some together :-? 8) Caper Quote Link to comment Share on other sites More sharing options...
