anytype of silicone? that i can buy on rona? how about the sand, can i just buy from rona? is it safe for my ciclids? goldfish? arowana? etc...

aquarium silicone and some others.alot will say right on it"ok for aquariums".some sand is loaded with silica which is very bad.your best bet is to rinse the sand thoroughly and read what type of sand it is.not familiar with rona so cant say.

Make sure you are careful with the silicon because some like the ones used in bathrooms are pigmented or have other things in them that can leech out and kill fish (don't worry, thankfully, not first hand experience).

If you're going to use PVC pipes, PVC pipe cement is fine but give it a day or two before using it in your tank. The smell has to be removed completely before use.

100% silicone (i.e. no special anti-mildew agents, etc.) works fine. Hot glue from a glue gun also.
