Hard water line stain. How to remove?

prsnlty · Nov 26, 2011

My husband purchased a 125 gallon all glass tank that was previously used as a turtle tank. He did this sight unseen as he drives a truck and was on the road at the time. The man assured him it was in great shape and would deliver. (It was supposed to be a birthday surprise for me). Anyway, it had many scratches but the worst problem was the hard water line since it was kept at 1/3rd the depth of the tank. I can't remove it to save my life! Any suggestions? I tried vinegar concoctions, lemon, razor blades and it just won't come off

Thanks

Welcome to Reef2Reef!

Does the line show up when the tank is full of water?

Maybe try some muratic acid? I wonder if it would harm the silicone?

Thank you

Nothing helped, I tried virtually every thing out there. The tank bowed and would not hold a strong seal so I replaced it with a brand new one. Maybe it was a blessing

LOL. There's nothing like seeing your prized contents in CLEAR view!

Good for you and I am excited to see some progress on it!

Yea, it was probably etched. I've had similar problems when i was trying to clean the glass tops on my used tank. I tried vinegar, clr, rubbing compound, razors, bar keepers friend. Nothing worked, it just stayed all hazy.
