I would like to get some advice on removing old stain lines from the inside of my tank, the old owner left the tank sitting with old water about ten cm high for ages and now the tank is fully established and running nicely those lines dont look to nice at all, any help would be greatly appreciated cheers.

since your tank is now running, it is not possible to use lemon
on it. but you can scrub it with scoth brite#96

I've tried the coarse algae scrubbers but had no effect.

Hmmm...yeah with it running I can't think of anything that you could use on it.

Maybe just keep scrubbing it and hopefully over time with it being filled with water the marks will go away.

Maybe try one of the scrapers that have a razor blade type end on them? Might be able to scrape some of it off then.

Is there fish in it at the moment? If not, I'd say drain, remove gravel and ornaments, and use white vinegar on the stains. I had them on my old tank, and a bit of vinegar had them off in no time, and with very little elbow grease. The stains are usually limescale from hard water. Acid will chew them away easily.

Cheers

I agree, they limescale marks are really difficult to remove when the tank is full. You can temporarily move your fish to a large container, move the water, filter and heater. Clean the tank and then wash thoroughly, then put everything back into the tank

Might try that when i change the substrate next week, what a mission thats going to be, should have taken more time when initially setting up the tank but was just to exited to get it all running. Cheers very much for the advice.

just use a simple razor blade and carefully scrape it away

surely if u used a razor ud have to drain tank anyway as it would all go into your water so may aswell drain first

not necessarly just drop it to the old water line and scrape it off if it goes in the water use a net to scoop it up no big deal work smarter not harder as well if ya'll have a good filtration unit you should be fine

hmmmm suppose, but id rather do a drain...gives me an excuse to play with ma fish without the mrs complainin!!
