Our house has a full on HRV system. All of the air in the home is exchanged approximately every 7hrs. I don't think I am going to pop a whole in the wall for more fresh air. Should I do something else to bump my pH up? I am running Tailored Marine Ca, Alk & Mg on my doser and topping up with RODI.
I can't honestly say the offending mat isn't dinoflagellates. I'm not educated enough to say either way. Feel free to come on over and take a look for yourself if you have time!
Haahaa I always feel like a little kid when you make comments like this

"You have your BP effluent plumbed direct to your skimmer inlet, right?" Yes, I do. Before it was within a couple inches of the skimmer intake, but now it's essentially touching the red dragon intake.
Cheers,
