Quarantine / Water top off station:
55g drum is fed cold water from a near by water line going to the water heater. Inside is a float valve that stops barrel from overfilling, however I do not plan to keep water supply on all the time and just turn in one once a week or so to top off the top off That way I'm not testing that float valve all the time with fairly high water pressure.
From there 1/4" RO tubing will be ran through the attic to the sump, where it will connect to same type float valve. This system is simply gravity fed, that's why the 55g barrel is on a top shelf Water pressure here is not too high, so float valve can easily handle it 24/7.
Below the drum is a shelf for quarantine tanks. Two 20g long aquarium with HOB filters. Mainly running them right now to get a start of some bacteria culture on few sponges. For filters I used SeaChem Tidal 55. Not sure how these are rated for 55g, seem fairly weak even in 20g lol, but should be good there. I do have plenty of Poret foam to fit inside them or around intakes if become needed, say for a breeding tank, if I decide to do that down the line once or twice. Aside from that each tank has 150w heater, although being in garage they would not be needed most of the time in Florida. I would more likely need to throw ice cubes in there hehe. Fan on the side might help as well a bit. Light are nothing special, just two flood bulbs, type I used before to grow algae in refugium in reef tanks, so in case I want to keep some plants in there for a bit, they will have something to use. As for the controller there is a smart power strip from Kasa, that just has timers going for lights and the fan and Coralvue Hydros XS with its 4 outlet power strip to control filters, measure temps, and control heaters based on that. I set up 79 to 82 band in the controller for when to keep heaters on and both heaters are set to around 80 degrees for now. That way power strip is not clicking all the time as heaters just hover around 80, but when temp go above 82, they are cut off, be that from just garage temps or heater getting stuck on.
And under all that just some storage area for various aquarium related things.
