After months, literally, of planning and design. I will finally be setting up a propagation tank for growing out SPS frags. I thought it would be fun to start growing out some nice sized frags for trades. Mostly the frags are for local trading and money from the LFS. I wanted to do it as easily as possible with as little equipment being added to the systems as possible. So this will be hooked into my main reef in between the tank and sump. The design is based on raceways used in raising fish in commercial fisheries. I originally got the idea from a part of Anthony Calfo's book on coral propagation, then modified it to fit my needs.
Water will go down the main tank overflows into a refugium then into the raceway. From the raceway to the sump then pumped back to the main tank. There should be very strong flow thoughout the raceway, no dead spots. The channels are 5" across and I expect to see about 800-1000 GPH going through it. I'm planning on using one XM 20000K 250W MH lamp over it. The raceway is only 7" deep, but the whole size is 32"L x 32"W, so I should be able to get very strong light, even from the XM lamp
, and very strong flow.
Anyway the raceway is still being built, Brent over at Barr Aquatic Systems has been great. Hopefully I will have it in another few weeks.
But here are some shots of it, in a semi-completed state.
