I'm getting quite the algae selection - and not the good kind. It's OK. I think it is part of the progression of the ecosystem, which is trying to get balance. I remove bits and pieces in a patchy way. My crew hasn't quite caught up, but I think it will.

I try to keep the grasses cleanish so they get plenty of light. It gives me the opportunity to evaluate their vigor. They seem to be in good health. They still have epiphytic algae, which is tricky to remove completely. So, with some, I prune the whole blade. Unfortunately, cleaning them disturbs the roots, so it's a balancing act.

My overall algae strategy is to keep exporting it to remove excess nutrients, favoring the red macros, which don't need a lot, and the grasses, which can get their nutrients from the substrate. I still have a few more herbivores and detrivores to add as well. At some point, my 'cast of thousands' will reach an equilibrium with algae production. I'll continue to add the macros I want, and when I feel like there is enough biomass, I will resume CO2 injection.

Next additions will be filter feeders. These will come in with live rock. Probably three weeks away. For now I'll keeping watching and thinking, and let Nature take its course.

Michael, are you running the return pump now or still just moving water via wave maker?

I have not yet turned on my main circulation pump. I do have a canister filter and the wave pump going, so water circulation is pretty good, but not great. I want to give the seagrasses time to get firmly rooted before turning it on. Once I do turn it on, things will change pretty radically. With much more current, the sand bar will be sculpted into who knows what shape. I also have the unknown of how the waves will be effected. My guess is that they will stay roughly the same, or possible get bigger. We'll have to wait and see.

Did you bring it up to point out that algae will be reduced by increased current? I found that to be true. However, my experience in v1 was that some algae was decreased, and some increased. Apparently, some algae like strong current. I think the biggest difference in this version is that I have a more complete crew in place to keep it cropped down.

I loved the pics, sorry for not responding sooner. The algae issues are just a life cycle phase of the tank, and I think that you're adapting and moving in the right direction with executing your plan.
