Hi everyone!
I am new to the forum but I have had my FBTs since April of this year. I use the dechlorinating stuff in the water when I clean the tank but over time this white scum has moved across the front of my tank, which I am sure is calcium deposit, but I can't get it off! I have tried to scrub inside and outside of the tank with regular hot water and with vinegar water (of course not with the toads in there and of course after a vinegar clean I always wash/rinse out the tank to remove the vinegar). I have used a sponge, paper towel and those green scratchy scrub things and nothing is taking it off. I know I could use something stronger but I am concerned about using chemicals in the tank, even if I really really rinse it out good. Anybody have any ideas on how to get this off of my tank?
