So just recently like yesterday my tank looks cloudy...so i looked closer and it was just lotssss of little bubbles, i have a 125, its been running great for the past couple months now just lotsssss of little bubbles, any ideas?
If you have external canister filters, check the seals. I know with the Filstar XP series, the O-Ring on the motor housing wears out and allows air to get sucked in. You can hear when it happens. It then shoots out a ton of tiny bubles that go all over the place and make the tank look cloudy.
Replace any O-rings that you can. See what happens.
