I am redesigning my fishroom. Going from 113 tanks to about 45. I raise fancy guppies and over the past several years have been adding plants (Java Fern & Java Moss) to bare tanks. I think it has really helped with algae problems and water quality.

I am going to put in a central filter- don't know what kind at this point. Was wondering if anyone had experience with a refugium type filter- kind of like those used for reefs only for freshwater.

I have two racks. The first has 11- 20 gal tanks and 17- 5 gals with three connected 50 gal tanks as a sump. The second has 7- 10 gals and 9- 5's with two 50 gal sumps.

One of my ideas is to put in a NPT in the sump of the larger system. I have no idea what type of plants to use and if I should leave the lights on all the time as in a reef refugium. What do you guys think? Is this even in the realm of possibility?

Thanks for any help.
