Getting parts ready for the new tank. I have a free next reef sump to use (it had cracked baffle but I fixed it) it's only 30g so I bought a 40 breeder and will connect them with bulkheads under the stand. They both just fit. Since this new tank will be next to my 120 I am going to connect the sumps with with some flex PVC pipe. I don't plan on having very much water movement between them. I will have the UV unit in the 120 discharge in the sump of the 180, it's only about 100gph. This way I can use the drain on the 120 and drip RO water to both tanks. The horizontal distance would be to great for a drain to work in the sump of the 180, so this should work pretty well. I have a dual head masterflex variable speed pump with easy change heads that I use for the RO/DI from 2 44g burtes linked in the back room. Will give a total volume of 350g give or take a bit. Will use separate return pumps, heaters and media in each sump though.
Got the stand today and cut plywood for a solid top. Will drill the 40b this weekend. It's pretty fun! Unlike my 120 I am going to go all ultra flex pvc plumbing. Hard line looks nice, but ultra flex just works so well.
I am planning on doing some small rays and SD in the 180 still, although it might take a while to find some.
