My 170g cube

Probe holders coming soon.

So bright that I have a hard time taking pictures of it.

Did you do a full load test? One issue I have for this kind of rack is that once. I have full load and it’s so easy to fail, since the magnet can’t hold on to the external ones.

I haven't done the load testing yet.

I'm not worried about the magnets holding, I went overboard on magnet selection. I'm more worried about the design failing.

I'll be doing some load testing this evening

I thought the material color was going to look cool.

It is obnoxious in the display.

A few in the frag tank might be OK.

I did some testing today. In open air mounted to half in material, the rack held 8oz of frag discs just fine. Around 10oz it became unstable. If I flip it upside down (magnets above the rack) it held almost a pound before starting to slide down.

In tank on half inch glass it held almost a pound before peeling away.

Are the mangroves staying in the overflow?
I would worry about roots and crud blocking things.

in that case id like to order some when you are ready. but not in green

They have adjusted well (they were grown in freshwater) to the tank and I'm getting new leaves. I am still thinking about how to manage root growth.

I have them sitting pretty deep so they get light from the kessils. the roots aren't an issue for now but I have to keep an eye on it.

For what it’s worth you would have better mechanics for load bearing if the magnets were higher up with a stabilizing bar dropping down, rather than having the magnets at the bottom of the stabilizing bar.

Agreed. The rack hold a lot more weight that way but blocks the view of two frag spots.

I'm thinking about getting long rectangular magnets for another version to keep the same strength with a lower profile.

Someone suggested I run my CO2 scrubber input from the Skimmer collection cup. The theory is since the air in the Skimmer has already been scrubbed, the media should last longer and be more efficient.

I also replaced my solenoid for the scrubber from a random one, that didn't properly open and close due to low pressure of Skimmer vacuum, to the apex one and used one of the 24v ports on the EB832. One less plug being used, more reliable valve and more efficient media.

The higher flow and stable nutrients have paid off with much better daytime PE.

 

[grizfyrfyter]

PE on my WD. Just a quick shot in auto mode of my phone. Damn fish make it impossible to get a descent shot.

 

[grizfyrfyter]

Mangroves are doing well.

 

[grizfyrfyter]

Little grafted Monti frag. Look forward to this one getting bigger.

I’ve heard this a bit different, that you should have your air intake for the skimmer come from your CO2 scrubber, with the idea that CO2 depleted air (high pH) will be dissolving into your tank water more efficiently.

Skimmers don’t actively deplete CO2, though if you have a semi-closed loop of air from your skimmer cup into CO2 scrubber feeding your skimmer then going back into the CO2 scrubber, you won’t go through media as fast because you won’t be scrubbing as much CO2 (less effective). You also won’t be exchanging O2 as well in the skimmer.

 

[grizfyrfyter]

The Skimmer has always been pulling air from the scrubber. Now it's just a closed loop.

If you have a pH monitor it would be interesting to see how that affects it
