Today I read 0 ppm on Amonia and Nitrite, exactly 12 days after adding a fish to my tank to start it cycling. I am using 2 DIY PVC overflow's made of 1 1/4 inch pipe, a 90 quart sterilite container for a sump (the dimensions are similar to 20 long), and stackable sterlite drawers for my trickle filter. I bought a set of stackable drawers that had one shallow drawer of about 2 inches deep, and 2 full size drawers. The shallow drawer holds a fliter pad and acts as my trickle tray. The first large drawer is full of scrubbies, and a liter of matrix media I had hanging around. The second full sized drawer is filled a little more than half way with scrubbies, egg crate over them and filter floss and a blue filter pad on top. About half of the scrubbies in the bottom drawer are submerged. I'm using a quiet one 6000 pump, and with head height and 90's I figure I'm at about 900 gph
It may have cycled a little faster, however I did 2 - 30%water
changes in that time and the only dechlorinator I had was aquamel+ which also is an amonia lock. I've heard that amonia locks may slow cycling. Long story short, it only took my DIY filter one day longer than the Eheim Pro 3 did in the Eheim VS FX5 test that was posted on this forum. I'm pretty happy about that.
