Can u explain in better detail of how to make an in tank refugium? Also,I am thinking of a clown fish,3 live rocks,some cleaner crabs,snales and possibly a yellow tiger jawfish in a 30 gallon tank. So what do u think now? Any suggestions are greatly appreciated.
One the best and least expensive things I did on my 55 g was just cram in an 1/4" square plastic grid light diffusers use in drop ceilings. (Egg crate).
I put it in 3" in front of the back glass with rocks at the bottom and my powerheads at the top.
I then added 2 utility fixtures 6" behind the tank pointing forward to light up that area.
So the last 3" of the tank is now a refugium and the area in front of that has the rocks, fish and corals.
So an in tank refugium is just some area of the tank partitioned off to keep the fish away from the macros. In my case with added lights to get the macros growing.
Nitrates dropped to 0 in 3 weeks, and my two tangs would graze on the macros that poke through the egg crate all day. Smaller fish even would go between the squares and browse around in the refugium area.
egg crate $10_________$10
light fixtures 2@$7.9 ___$16
tubes__2@2-tubes $7___$14
total cost $50 or so.
No only one of the least expensive things I did but also one of the most effective in terms of fish and tank health. After a few months even phosphates dropped to 0. Plus one time I basically doubled my fish load. With no ammoni/nitrIte spikes but an initial nitrate spike that returned to 0 3 weeks later.
still just my .02
