new tank help!

[navydiscus]

Just picked up my new, used tank. Only problem is it was used as a reef tank prior to, and there are quite a bit of calcium deposits on the tank. Other than clr and white vinegar, does anyone have any recommendations to get this stuff off.

Warm water and a little bit of vinegar mixin together, wipe the area with that solution, and then use razor to take them out....make sure to rinse your tank with water again after that

Put as much vinegar as you can afford into the tank. The higher the concentration of vinegar, the faster the calcium falls right off. I guess it depends on the size of the tank, but I'd get gallons of vinegar, 3-5 gallons or so. Then fill with water, put a power head in, and run over night. It'll mostly just fall off. Also if you have any other calcium encrusted equipment, throw it into the tank too. Might as well get it all cleaned at the same time. Then just rinse everything well with clean water.
