I had a bit of a cyano problem and a lot of a caulerpa problem.
My tests indicated zero on everything, but I doubted them and bought new kits just to find zero across the board.
Ended up swapping my old t5's out for LED and the problems cleared up quickly.

Since you're already running a Radion my circumstances don't really apply to you and I'm just consuming bandwidth. But maybe too much sunlight or red from the Radion?

Yeah I thought about the light as it didn't happen till I got to 80%. Ill wipe it off the board and see what happens

That would be interesting to see your results. So far I only have my red and green channel up to 30% as it is. I wonder if I'll see a recurring problem when I bump my intensities up more.

Since I started using MB7 more than a year ago, have never had a problem again with cyano. And my P04 and N03 is nowhere near zero. And I use Radions.

Sorry but what is mb7

Nvm. I found it. And def look into it

Microbacter 7 from Brightwell Aquatics. Adds beneficial bacteria which out competes cyano. A must use with bio pellets.

Many LFS's carry it.

Thank you

The label on mb7 says it reduces organic carbon. Since prodibio is a form of carbon dosing will it affect the prodibio performance.

Sorry for the inexperience lol

Don't know about prodibio, but it is recommended to be used with bio pellets, which is carbon dosing. It also prevents a lot of the unsightly mulm build-up that can clog reactors and filters.
