<p>Thanks George. I thought about removing the pre filters and letting the pumps move solids, but I had a bed of gravel in the FT originally and didn't want to jam the impeller. Now the gravel is gone so I think I will try what you describe.</p>
<p>I did a test about a week ago before I changed everything around, the ammonia was 1ppm and nitrite was .25ppm, ph-7, nitrate-3ppm. I believe the gravel bed in the FT was holding too much waste, causing the spike in levels. I plan to test again this…</p>

<p>If you have sufficient grow beds, they will serve as filters. The pumps shouldn't need a filter since the grow beds are filters - you want the pump to pick up solids and pump to the grow beds. I've never tried perlite but I don't think it's much recommended for aquaponics. Usually people used something like 3/4 inch gravel.</p>
<p>What do your tests show for ammonia and nitrite? Those are two things that a biological filter should be taking care of for you.</p>

<p>So I have been watching some videos, and it seems that most folks are using a bottom drain and sucking the waste through a swirl filter. I am not cutting a hole in the bottom of my pond, so I need to find a different approach.</p>
