So I’ve had my 55 gal for 4 or 5 years now and there was a time where it sat in a shed for about 8 months. I’ve tried lots of things to clear up the glass but nothing has helped. I’ve even taken the tank all the way down and scrubbed it for a long time using Bar Keeper’s Friend and it still won’t go away. In the pics you can see at the top of the tank where is it clear. My water is crystal clear. Using a Fluval 406 canister and also a fluval C4 HoB. You can see the haze in the glass better from different angles and lighting. Any secret tricks to fix this?
