thanks steve ill check on that tomorrow normally i would just use clear but this tank was previously done with black

Muriadic acid works great on coraline removal.

a very diluted form of HCl will do the trick, lol for real

acids worry me i would have towash it really well but ill look into it thanks. thereis alot of coraline onthe glass he has a great culture of it lol.

Vinegear work every time...

Just mix up a strong water/vin mix and let it circulate in there for a few hours...

your coraline will come off easy after that.

Really, the best thing is just use a new razor blade. Muriatic acid is great, but you need to use it outside, and you have to neutralize it before disposal. If you can fill the tank and run it with lots of vinegar, that works, but again, you then need to drain it all and clean it up.

x2 on the razerblades an elbow grease, pick up a box an they will last forever.

I cleaned up my old tank with viniger and a razor blade. I layed the tank on its front with a 1" block under the edge and put enough viniger in so it wouldn't spill out. let it sit about 15 min then tip the tank up right again and use the rasor to get anything left off, then repeat for each side.

took me maybe an hour with about 15 to 20 min of actual work.
