It couldn't have been die-off from the rock because it was dry base rock. I just needed a few to fill in gaps. I rinsed it a million times-even with the water hose at full blast so I dont know whats going on. I done a 20 gal
water change and replaced the filter media but the nitrates didnt go down at all! Any suggestions for decreasing the nitrates. Tank is a 75 gal
, wet/dry filter-can't remember specs om filter but it was built for a 125 gal
tank, about 70 lbs LR
, only fish now are 2 percula clowns, 2 blue devil damsels, 2 emerald crabs, various snails and hermits. I dont have a skimmer yet.
