    Removing salt residue from tank glass

    I have a tank that has some filmy white residue on the glass. i've tried wiping it off with a wet rag, but when the glass drys, it is still there. i'm not sure if it is from encrusting salt or something else. what reef safe product can be used to remove this white film from the glass.

    Are we talking a glass top covering your tank? if so, thats the nature of the beast and thats why most reefers ditch the glass tops.It also helps with gas exchange and heat issues. You will get more evaporation but I find that a good thing as I can topoff more often with Kalk. If you want to keep thoses glass canopy's you can use CRL [available at any WAL-MART] to get rid of the calcium deposit of which your seeing. Hope I helped.

    hi John,

    no, i'm not talking about glass canopies. the residue it actually on all four sides of the tank around the top 3 inches. i know CLR would remove it, but i don't know if it's reef safe or not. just wondering if anyone knows of anything reef safe.

    I use R/O water and vinegar. About 4 to one mix.

    The only thing two reef keepers will agree on, is what the third reef keeper is doing wrong!

    Are we talking under the water? or is your water riding fairly low? Your not talking about eurobracing are you? sorry but half a sleep here. If your just talking about the hard calcerous build up were the magnet can't get it off near the top then use a KENT scraper[with metal attchment] or an old credit card. works perfect.

    i bought the tank used and it was sitting uncleaned for awhile before i bought it. needless to say, i spent several hours cleaning the algea and crud off the glass. now, there are several areas where the glass has a semi clear milky film on it. i've used a razor blade and vinegar on a scrub pad, all to no avail. Any ideas?

    Well, if it is still empty then try some comet on a cloth and gently scrub it. The mild abrasive should remove the film and not scratch the glass.Or even baking soda- which is definitely reef safe. Obviously you will need to rinse it really well, but the bleach will dissipate anyway. OR soak it in straight vinegar first, if it is really stubborn.
