I can't even see in the tank hardly the magnet cleaner does nothing tried a bank card might aswell not work for how much it gets off i have lowered my lights and reduced the amount they are on now but anything else i have to do i had GHA before this and turned the lights off for a week but i have coral now and more arriving on wednesday so cant do that
stay away from the silicone on the corners but lay a razorblade flat against the glass and scrape it away. 5 mins later you'll have clean glass. from there make a point of using the magnetic cleaner every few days and you'll be golden!
