Freshwater Aquarium/cleaning out tank


hi..i have a 30 gal freshwater aquarium that is used. right now i am trying to figure out how to take out the stains inside it. the algae is gone thanks to a razor. the water stains are another thing. without going to the store and spending a lot on tank cleaner, is there anything you know of that i could use instead. the razor does nothing to take the water stains out and of course im trying to avoid caustic chemicals. thank you!!

Hi James

You can use vinegar and water to clean the tank...that should take care of the water stains. If not, you can add a little baking soda to the vinegar and water mix. Rinse the tank really well and it should be good to go.

Just don't use any bleach or detergents to clean the tank, regardless of how well you rinse, there could still be residue left over that will kill your fish.

Hope this helps you, good luck!

I own and maintain several freshwater aquariums from 2 to 180 gallon. I can answer most questions about freshwater aquariums, including setup, cycling, maintenance, compatible tank mates, feeding. Moving? I've moved fish both across town and across the country and can help you get your little aquatic friends to their new home safely. I know and have experience with most freshwater community fish, South American Cichlids and African Cichlids. I don't answer questions about Goldfish or keeping Goldfish with Tropical Fish. I also don't answer questions about keeping crustaceans (shrimp, snails, crabs etc) with Tropical Fish, nor questions about saltwater fish or aquariums. I'm not available to answer questions on weekends, this is when I do maintenance on my own tanks.


Many years of personal experience with community tank fish, semi-aggressive fish (Barbs, Tetras, etc), Angels, South American Cichlids and African Cichlids.
