So, here’s the current plan for the addition .....
1. Main pump will be a PanWorld 100px that I have laying around. Should be able to get 400 or so out of it. Only other choice is a PW40. I might try it, but probably underpowered.
2. Lights will be a trio of kessil 360 we that got mothballed when I replaced them with the 360x.
3. Purchased a new MP40QD. I’ll want to attach it to my apex WXM which means I have to futz with the firmware. That never goes well chez Simon.
4. System skimmer, CaRx, etc. will all handle the addition without breaking a sweat.
5. Will see if an additional heater is required in the sump. I’m guessing not, but I have a bunch on hand as needed. Chiller will handle the extra just fine.
6. Feed for the tank will run through a 55 watt TMC UV in an attempt to 'isolate' the tank.
Tank will have an integrated external overflow, so just a grill along the top of the back, no skim box. Kinda wish I’d gone that route with the 450. Never have had a tank where there wasn’t something I wished I’d done differently.
Existing fish that will have glorious space include my longnose black tang, a small Achilles, an even smaller convict and a pair of black/white clowns.
