120 gallon rimless with basement sump

Wow you have made a lot of progress since I was last on the forum. My room renovations are about done and now I'm in the planning stages for my stand and plumbing. I'm going to make a concrete top for my stand.



Thanks. Concrete top is an interesting approach I've never seen. Definitely following along.
 
Looks great! Also from NE Ohio area as well. Currently under construction on my build but I'll be using some of your DIY ideas. I think I need to get my build thread started.

Start the thread! If nothing else it's a good way to reflect on progress. A lot of my ideas were adapted from others so there might be someone else you can help by doing it
 
First off, great setup! I’m starting a SLOW 120 build myself and had a couple questions - I really like the “floating” canopy, would you mind sharing a copy of the invoice for the 80/20 frame that you used? I’ve tried looking on various 80/20 websites but I’m a little DIY challenged which I’m finding is a huge detriment in this hobby (lots of expensive, poorly mfgd equipment IMO). Second, any sump mfg you would rec’d for an external return pump setup like yours? Thanks again for sharing

For the sump, I don't have experience with sump manufacturers, but you could certainly drill any of them to accommodate an external pump. Drilling acrylic is easier and less stressful than glass IMO.
 
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
 
Got a microscope and it clearly looks like dino ostreopsis. I've read a lot up on it and going with the dirty method to bring up nutrients. Also going to focus on regular manual removal. Corals are all stressed so hoping for some progress now that I know what I'm battling.
