Our tank is 18 months old, no signs yet of coralline algae, we have a few red patches in some crevices in the rocks, nothing on the substrate, I'm going to assume it's cyano.

It's by no means serious enough to try chemiclean or would I probably want to.

Seen a few things that say using MB7 would add some decent bacteria to the system which may help, but I've also seen a post where someone said adding MB7 will damage our developing system as its maturing.

Any thoughts?

What kind of bacteria does it add? Is that a type your tank needs?

What are the upsides to adding it?

It dropped my phosphates…I guess the downside is your phosphates going to zero if you’re not careful.
My phosphate was 0.08 but then recently my small amounts of algae in the display disappeared and the phosphate went to 0.22, I was previously dosing phosphate to keep it above zero, so I'll carefully watch that knowing I have my doser still set up and ready

no harm with adding it to your tank. it adds biodiversity to the tank, however not as diverse as originally advertised. @telegraham sent in a sample of MB7 for testing and it ended up just having 1 main strand, and very little of the rest.

there is this as well you can read through:

also this for cyano maintenance:

Hi there, do you happen to have some pictures of the affected areas you could show us?

seems more of a flow issue considering the spots where the cyano is at. adding a gyre or slightly increasing wavepump speed will definitely help, as well as weekly bastering of the rocks to suspend the mulm/detritus into the water column to get filtered out by socks/skimmer

I've got a gyre running at 80% (ramping up to 80%) plus 2x sicce wavemakers, I was blowing the red patches off as it was hard to syphon out where it was

Just increased the flow on the sicce powerheads to 95% on the impulse setting, these however are on the side panels at the back firing at each other so I'm not sure what more that will achieve, can't really up the gyre as my torch will be damaged

I think there can be downsides to adding bacteria to a reef tank, unless it is intended just as food for corals, but outcompeting dinos and maybe cyano for space may be one of the desirable uses.

I don’t think nutrients are going to drop enough to be any sort of issue.

Thanks, I grab a bottle and some live phyto
