I'm getting back in the hobby after taking to long of a break side 2012. I just picked up a 40B and a 20L for the sump. This will be a mixed reef tank. I'm torn between spending the money upfront for a Kessel ap9x or saving a little money on a reef breeder photon 32's. I know in the future I will upgrade to a 4f 120 gallon. Which then I could use swap over the Kessel. I'm open to other options as well. Budget is around 700.
