A couple of people already know, but most don't. I've caught the frag tank bug - mostly because I'm sick of frags vanishing down to the back of the tank where I can't get them!
So:
3x1x1 frag tank to be hooked into this system. It will sit on the bottom shelf of an adjacent tank stand with the plumbing running back over to the sump. They're quite close, and it's not up very high so it shouldn't be an issue. This size should fit the space I have for it quite well. It's probably overkill, but I'm wanting to focus on establishing colonies of things like zoas before I put them into the DT. Locally, no one sells coral either, so perhaps there might be some market down there later on for local trades or making a few bucks to cover the cost....
The tank has been ordered. Going for pretty straight forward approach. Ideally, I want to have it two tiered - basically sand base with egg crate in it, Back half of tank will have a shelf that'll be about 15cm or so up. Under it I'll have some broken up live rock and a heater back there. Hard to explain, will make more sense when it's done :p
Ideally, it'll be something that I can isolate and run as an independent (though sump and skimmerless) system if necessary. The live rock hidden under the back shelf will help with that, and will let me get rid of some of the excess out of the sump. Will also be a good ready source for rock to grow things on.
The idea of the heater at the back is to assist with reducing heat loss. The room is typically cold, and the main tank heaters run off a single controller. This way the system will have an independent heater as well.
Plumbing: I've ordered hansen bulk heads, ball valve and some elbows. I prefer to avoid 90deg, but I won't have a lot of space behind this tank, so 90deg it is. These should be here tomorrow. The rest of it will be stuff either laying around or will be bought from Bunnings.
Return: I have a spare Hailea 1000l pump kicking around. Used to use it on the nano, and it managed to maintain some pretty decent head when it had to push over 6 foot up, so it should do the job. Only 2 foot of head on this, so should be fine.
Lighting: Just built a 24 LED Aquastyleonline job - 10 x 10000k whites, 10x royal blue, 2x red, 2 xUV, 2 x meanwell drivers. Mounted on the old heatsink from my nano LED build and currently using a RapidLED controller. Ordered from them Saturday. FedEx tried to deliver to me Monday, so can't complain about turn around time.
Flow: NFI yet. I have a spare JVP kicking around. Probably way too much flow in a tank with 100l~ water, but anyway. I have a smaller one in the DT that I may swap it over for if it's a problem.
