Whats the best way to get all the purple stuff off the back on a class tank. I bought it used, but would like to have the black paint showing. should i do it before i put water in, or after?

Thanks

Is the tank running? By "purple stuff" do you mean the encrusting algae commonly called coralline?

If it is coralline, soften it with full strength vinegar, then scrape with a razor blade. Just be careful around the tank's silicone joints. If the tank is already running, just go after it with the razor and skip the vinegar.

Get some old dish towels and soak them in the vinegar, then hang them so they are laying against the coralline on the glass. IME this is one of the best ways to ensure it soaks in for a good amount of time - otherwise the vinegar will run off or evaporate.

If its empty lay it on its back and let the vinegar soak in. Vinegar is less than $2 a gallon so just pour the whole gallon in full strength.
