Update on the tank.
I began to run into some issues with what I thought was cyano.
After a bit of frustration, I tried two approaches, increase flow and red slime/chemiclean
I upgraded the gyre 230s to the newer 350s. I like the pumps, but it's only slowing the growth.
I tried blackout followed by red slime remover. Looked like it was gone, but slowly came back. I decided to try chemiclean several weeks later, but that seemed to do nothing.
The only thing I could think of is that something growing in my saltwater storage container was causing problems. Here was the inside of it
The black streaks were actually below the water line. I could also wipe the sides of the container and a slime was on the paper towel. My only thought is that I didn't thoroughly clean the barrel and something remained that fed bacteria.
My solution, get a proper water storage container. I picked up a norwesco 65 gallon.
One thing I'm trying differently from my old tank is connecting the auto water change line directly to the plumbing that exits the bulkhead on the bottom. I like this setup better than finding a way to run the line through the top of the tank. Only risk is that if that line accidentally gets yanked out I've got water shooting out the hole.
If anyone has ideas on how to battle my cyano (maybe it's not cyano) problem, I'm all ears
