Crushed Coral Backing

[raiderfan]

THE PET STORE ACTUALLY PUTS A KIND OF LIQUID ON THE BACK OF THE TANKS AND POURS THE CRUSHED CORAL ON IT WHEN IT DRIES IT STICKS TO THE BACK OF THE TANK AND BECOMES THE BACKING. THE GUY SPEAKS BROKEN ENGLISH AND THE BEST HE CAN CALL IT IS LIQUID FIBERGLASS WHICH I AM SURE IS NOT WHAT IT IS. HIS TANKS ARE SET UP LIKE THAT AND HE DOESN'T HAVE ANY PROBLEMS WITH IT. THE ALGEA I HAVE MAY BE MORE OF A BROWNISH COLOR. IT MAY BE THE LIGHTS THAT MAKE IT LOOK ORANGE. THE GUY AT THE PET STORE HAS A STORE TANK THAT I HAVE SEEN SET UP WITH EELS AND OTHER FISH FOR AT LEAST 2 YEARS. THIS I KNOW BECAUSE I HAVE WATCHED THE EEL AND FISH GROW OVER TIME

Here is the same reply that I put on your other post about the cc backing.
I have seen tanks with gravel and coral backing, glued on with an acrylic adhesive. It is pretty common in the freshwater hobby. I have a 15 gallon in the garage with a backing of gravel.
The only thing is, all that I have seen, this backing is applied to the back on the OUTSIDE of the tank. For the sole purpose not getting algae on it. I think the person that you got this off of has the whole thing backwards.
There is no way you can get all the algae off unless you use algae remover, and that is detrimental to the tank for saltwater, although common to use in freshwater.
Even if you do remove it, it will get other kinds of algae on it again.
I would complain to the person you bought this from, and return it. I see nothing possitive with the backing on the inside of the tank
