Interested in your opinion on this.
I've seen it happen in two tanks where the first tank was struggling with HA and I suggested to the owner to dose MB7 to deal with it. It did take care of the HA after the loading period and a couple of weeks at the weekly dose dose. few weeks later at the weekly dose Cyano appeared and didn't stop even with syphoning and additional MB7 dosing.
LAter on he used Zeobac, Zeozyme and KZ coral snow and after few weeks cyano was gone.
Tank is 210G 1.5 yrs old with Deltec skimmer TC2060 and Deltec PO4 reactor and weekly 10% water change, decent flow (couple of MP40s and 2additional chinese wavemakers doinga decent job.
2nd tank is a 200 G tank with the same skimmer and Phosphate reactor with initally 2 Tunze 6105 and now 3. had a bit of cyano on the glass since months, MB7 took care of it initially but a couple of weeks in the maintenance dose and the cyano was back and now on many rocks and corals.
Is there any relationship or something I'm missing with MB7 that could lead to fueling Cyano somehow? The way I understand it is that these are 2 bacteria that theoratically should compete for the same nutrients?
Appreciate any input on this.
