Figured I'd update
Had to throw together a quicky aquaponics system; after one of the seedlings started showing some N deficiency...
Nothing fancy, using my catgrass 'popping' tray added 4 holes to the bottom - just to drain back to the tupperware; that's peat as a grow medium... mini Jebo HOB filter with foam from established filter... 3 smallish ameca splendens in the sump (you'd think in a big planted tank full of these buggers - the magic net scoop would catch more). Aqualifter on a timer (20 on 40 off) only using about 1/4 the flow - rest diverts back to the filter for now... Coralife 2x65 (4100k 55w bulbs).
48 hours after putting them in - wow... explosion of leaf growth... Using some KNO3 to keep NO3 levels up in the 20ppm range. Added some CTEM for good measure, pH is in the 6.6 range (peat is keeping it down - tap at the moment is in the 7.8 range)
