Clr

[karenvas3]

I bought a used 180 and it is covered with calcified coralline. Vinegar is not getting it off the overflow box. It did a great job on the glass. I have read that one can use CLR to clean. I am wondering if anyone has ever used on a reef tank? Should I not worry about whit spots on overflow box and just leave it alone. I do find it rather unsightly.

I wouldn't worry about the coraline on the overflow box, as in time it will grow on there anyway. Basically you want to get the glass cleaned off, which you already did.

what is clr?
in a short time your over flow will be covered in new coraline.
try soaking a towel in vinegar and let it soak on the over flow.

Thanks for response. I did soak the towel in vinegar to no avail. I think I will just leave it and move on with next phase. Thanks.

Scrubby pad and hydrogen peroxide.

CLR....if it is what i think it is Calcium, Lime and Rust remover. If it is that i would not in anyway use that in a reef tank. That stuff is potent. Theres no way of knowing if there is any residual effects after, play it safe....if you really want to take it off use a razor blade and take your time, than scrub to take off what little remains

thanks evo, thats what i thought it was. i do use it on my pumps and lock line out of the tank, so i can rinse good.
i would leave it on their, it will be covered in new coraline soon.

I absolutely would not use CLR on any piece of equipment that get submerged. It may leave residues. For the overflows use a razor and vinegar. If it doesnt come off who cares. It will color up again once the tank becomes established. I had the same problem when I started my 150. I left it and it looks natural now..
