Hard water/ calcium deposits

Recommended Posts

This is kind of an obscure question but I cant be the only one here with an aquarium. (ironic, maybe blush) We have extremely hard water and there is hard water stains and calcium deposits all down the back of our tank and on the hood from the water evaporating. What can I use to get rid of the deposits other than sitting there with a razor for 6 hours scrapping everything off?

LCR should work (stands for lime, calcium, rust). It's a bit harsh to deal with but put it on and it will at least make the job easier than scraping without it. Obviously, don't get the solution in the tank.

If you want something non toxic then use Vinegar. It will remove the calcium deposits on the tank if you can let it soak on there.

Also, I have had as many as 15 tanks going at a time in my basement in the past and we have some of the worst water in the state. I have a reverse osmosis filter for our drinking water and I also used that to keep the tanks topped off. It may be more expensive to make but it eliminates the calcium deposits in the tank and it is better for the fish( Well you need a small amount of regular water in there) in the long run.

I use vinegar when I clean my tank. I've found the best thing is to keep adding water during the dry winter months every few days to eliminate the area that has deposits. I keep a empty gallon milk jug, fill it with hard water and let it sit 3 days and then dump it in.
