We have a 58ga Salt Tank with 40lbs LR
, 3 inch substrate, Red Sea Protein skimmer, Power Head 402, Coralife Aqualife Power Compact, 1 High Fin Red Banded Goby, 1 Anthias, 2 False Percs, 20 hermits, 9 Turbo Snails, 2 Cleaner Shrimp, 7 Med Mushrooms. Our Fluval 304 Filter has caused us our last headache (It does not seal anymore). We have read that a filter is not neccessary. I was wondering what the thoughts are in this forum. If it is necessary, can anyone recommend a reliable filter that is not plagued with issues like the Fluval 304.
