Hi! I hope this is a good place to post this...
i have 2 10G tanks and a 5G tank that are moldy and have, like, calcium buildup on the hoods, plants and the inside. how do i safely clean that? i don't know what to use, and how to go about it...the 10G tanks havn't been used for almost 6-7 months, and i have no clue how long the 5G has been empty.

Since they're moldy, you can soak them in a bleach solution.....ummm....I think the ratio is 1 part bleach to 19 parts water.
Rinse until you can't smell bleach. Then OD the water with conditioner. Let that set for a while.

Hard water spots can be removed with vinegar and elbow grease. Be careful, if they're acrylic, they'll scratch easily.

Someone said make sure the vinegar and bleach don't mix, not sure about that. Definitely don't mix bleach and ammonia.
