I tried this for a planted tank, and have had awful results. Anyone use this substrate with success?
50G with overflow
Co2 in sump, inline reactoron the return.
PH Controller (set only to read)/ 40ppm CO2
3" - 7" bed (Fluval Stratum)
Two Discus, half dozen cory's, ottos, and a BN Pleco.
Two AI light fixtures.
Tank has been up over a year.
Plants look awful, curled tips, algae grows on the leafs, etc...
Recently added a dosing pump
and Iron Gluconate
If I dump enough Phosphate in the water to bring it to 4ppm, it will be 0 within 6hrs
If I dose enough Nitrate to bring it to 60ppm, it will be 5 within 4hrs.
I cut most of the plants down to the roots. So it can't possibly be the plants using them up
Is the Stratum soaking up the nutrients?
Have sillicates in tap, tried 100% RODI refortified with Seachem Equilibrium, No more sillicates, but didnt affect diatoms (which only seem to grow on HC)
Dosing pump injecting every hour to hold:
Iron .4 - .8
CSM+B unknown, (1/8 as much as NPK)
Ive had tanks in the past that had more Nitrate at the end of the week than this one has after a few hours without dosing. What gives?
(I did put a bag of DeNitrate in the sump a year ago, but if I pull the media and put it in an a bowl of tank water, 24h later the nitrate levels are unchanged) and the 50g without the media in the sump is still dropping to nearly 0.
