I gotta give props to Sea Level, I had never heard of them before but I was actually pointed in their direction by a smaller shop. The store doesn't look like much but their prices are perfect (50% of World of Fish) and they carry bulk substrate. I got 200# of 1/16 - 1/8 river rock for $50.00 at World of Fish I would have got less than 50# for that money. Mag Drive 9.5 for $80.00 World of Fish is $225.00, Driftwood for 1/3 or less of WOF. They don't have everything but what they do have they treat you right on.
