Ive got a 20"(its actually 19.25") cpr hob fuge, it works great. I found a mantis in my LR when I first setup the tank(3 months ago) and its a good penality box until I can find someone to take him.
The pod production in my fuge is nutz too, millions and millions of pods with no predators in there. I was planning on adding some macro but Im now leaning twards adding some xenia to the fuge and phos/calc reactors (bye bye nitrates and hello coral!).
There is no risk of flooding with the cpr ones either because the return is above the tank. I do have a diy trap to keep the mantis out of the overflow, which if got clogged could cause it to flood the place with about ~20 gallons of water.. but thats just temporary. :happy:
I dont keep the fuge lit right now either (lights for fuge is the next purchase for sure), but I do have a couple pieces of LR in their for the pods. I've noticed that a few hundred sea squirts have popped up in the last 2 weeks too, I think thats because of the low light. Does anyone know if sea squirts have any benefits?
To sum it up, I give the cpr hob's 2 thumbs up. Esp for a newbie that doesn't want to tackle below or above fuge yet. Its way worth it for someone on a budget with a <50 gallon tank.
