My first tank was a 30 G FOWLR
. Unfortunately I only had a HOB
filter and nitrates ran wayyy up. And 10% weekly water changes didn't help much. How can they when they leave 90% of the nitrates behind.
But after my nitrates climbed to over 40ppm I bought a CPR Aquafuge PS, which is basically a 5 gal HOB
refugium and skimmer. I added chaeto and a light to the back and my nitrates dropped to 0. And that was without the filter as there was not enough room for the Aquafuge and a filter. I got it off ebay. Best thing I did for my 30 gal
