I am wondering where I can get rock for my new 240 gal
aquarium, all glass. I want to have a fish with perhaps live rock, but I want to build the reef system of rocks and corals and anenomes etc synthetically and dry prior to putting the water. questions:
Can I use plastic crates to support the rock to build them up quicker to a higher level in the tank?
Can I cut out the sides of the crates to make cave like areas under the mounted rock which will be glued (secured to the crates)?
What type of rock can I use?
I have heard the lava rock at most pet shops is a no no, is this true because of the phosphates and silica?
Can I use aquarium silicone sealer to attach the rocks to the crates?
That is enough of the basics. I have had seven salt tanks in the past but that was 10-12 years ago with undergravel filtration and canister filters. Lots of things have changed. For the better of course.
Thanks for the help with this dilema
