Is ‘Bar Keepers Friend’.... Reef Safe?

[1reeflover]

Bought a used 200 gal glass tank that has major Coralline residue on front pane of glass. Tried SOAKING WITH VINEGAR & SCRAPING with a RAZOR BLADE with NO RESULTS! This IS NOT your normal soak for 2 hours in vinegar & easily scrape with a razor blade!!! On another forum a reefer said he used ‘Bar Keepers Friend’ & had fantastic results! My question is : Has anyone used BKF & had good results? Or... has anyone else here had my similar situation & had something work for them? PLEASE NO COMMENTS ON USING A RAZOR WITH ELBOW GREASE & VINEGAR!!! IT DIDN’T WORK!!! Lol Thanks ahead of time!

I used it when I bought a used tank and it had hard water stains and all that nasty stuff. I got a Dual Action polisher and some barkeepers friend and went to town with it. Gave it a nice bath after I was done and so far so good.

Can't say I ended up with a perfectly clean tank tho. I thought it would have worked better from what I heard from others.

Why not some muriatic from the hardware store? No coralline can survive it.

Rushbattle... This stuff is so hard seems etched into the glass! Like I said soaked for hrs with vinegar & not a speck moved!!!

I certainly will look into muriatic for sure! Thanks!

Or think days instead of hours with the vinegar - but muriatic acid will certainly be quicker. Just be safe about it.

Your assumption of being etched into the glass is probably closer to tthe truth than you realize. If the vinegar soke and Bar Keepers Friend isn't removing it then its most likely etched. I had a similar issue with a 75 gal I bought a couple of years ago. I tried everything I could, including Cerium Oxide, glass is clean now but its etched. I ended up buying a new tank for display and the other became my bearded dragons new home.
As for the original question about BKF...just make sure you rinse the tank out real good and you should be fine
