.25 phosphate reading is very high, I'd say there lies your problem.
But, it sounds like a cyano dusting, gonna have to keep at it, until you get those phosphates down.

.025 is the same maybe I wrote it wrong but yes is like a dust working on a reactor for phosban

Most helpful link. Thanks. We're having a problem with Cyano. Maybe you know this too, is it true that a larger tank is a bit easier to keep in balance? We have just a small 45 gallon, but have considered going up to a 65. We have to make a choice soon, as our JBJ tank split right down the front of the glass and are borrowing someone else tank, while we make a decision. Thanks for the help.

Larger tank volume, meaning like 125g and up I would say. Moving up just 20g would be the same.

Agreed.

Every tank has its challenges. Just choose one you like.

Fwiw. I have a 55g w sump (70 gal vol) and a 30 sumpless. The 30 is a piece of cake. The 55 a little more weird at times. IMO. It's what's in the tank and the technique that effects the stability.

Wow! That's interesting. Do you have fewer livestock in the 30 sumpless? Is that why it's easier?
