Ok so im just starting out with this sump situation but my waters like bot clear at all seems like a ton of tiny bubbles all my water levels are right what could this be??
you can do a couple of things to try t pinpoint where the micro bubbles are coming from.
1- stop the skimmer.
2-stop the small pump to the reactors.
3- stop return pump and see if you have a very small leak at the union.
