WRONG ! ! ! I'm just saying.
For a 45 gal
tank, of course bigger is better. A sump would be preferred, but if you can only go HOB
, a refugium does work. I say this because I had one. Is a 5 gal
refugium a giant, no, but it is better than nothing and the chaeto grew very well for me. a simple clip on CFL lamp over the fuge worked wonders for my nitrites. I was getting up around 80ppm nitrates with a HOB
filter with nitrate resin pads, all to no avail. I removed the filter when my CPR Aquafuge PS (large) arrived, and it quickly took care of all my nitrate issues.
It holds more than squat for water (5 gals)
It WILL grow macro (very well too)
It was an efffective method to remove nutrients in a sumpless setup.
