Well just how much cyano do you have? Post some pics?

Sent from my Dungeon using mad Ninja Skillz.

Here are some quick shots. They aren't all corrected, unsharpened, bla bla bla but you get the idea!















Here is what came in the mail while I was gone.

From your pics, I'm not entirely convinced that is cyano. The color in the pics looks more of a brown color and snot-like? Have you seen dinoflagellates before? I'm a bit worried that is the beginning of dinos. What's your pH at? Which tester?

[Scythanith]

It's more reddish to maroon in colour. The pH from the profilux sensor is 7.9. It was calibrated a month ago. My pH has barely every went above 8.0 pH.

It doesn't get stringy or bubble up at night. I think I will replace my GFO with some new stuff. Get my GAC and ozone running full torque. Siphon out what's on the surface.

Any other suggestions?

Ok, maybe it's the sweet red Fungia making the algae look less cyano-like. I hope so, dinos suck. Is your fish room located on an outside wall of your basement? A small vent to outside can make a big difference for pH. It would be nice to keep it above 8.0. I'm not sure if ozone and biopellets play friendly together - Mr. Wilson might know more about that. You have your BP effluent plumbed direct to your skimmer inlet, right? Maybe dial back your BP effluent a bit to try to help with cyano. Siphoning will certainly be a big help.

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,
Scott

that is a very low air change rate, it should be about once every hour.
if you look a tight home has a natural air change rate going down to
0.33 /hour and they need mechanical ventilation to bring them up to that once per hour range.
