Sorry for the late reply.
Planted date 1/03/2020
230 litres 92x50x50
Seiryu stone and some wood.
Substrate : Help plants
Light: 2 White led lamps, (total 100 Watts and around 11125 lm).
7h per day
Filter jbl 1501 with 2 kg matrix + 100 ml purigen
Water change: Weekly 50%
I use 100%RO water without remineralise as I have seiryu stone and after 12h I get:
Co2 30 ppm during the light period
Fertilising Every day:
2 ppm NO3 (with KNO3)
0.5 ppm Po4 (with PH2PO4)
( K included in the KNO3 salt)
8ml Excel or easycarbo
Skimmer eheim 350
Auto Dosing pump
Added Power head circulation pump to increase water flow.
Removal of Sera co2 reactor 500 to increase water flow.
Added co2 neo aquaRio difuser installed.
Due to poor nutrients in the last measure I did before the last water change (no3 2 ppm, Po4 0,3ppm) I have decided to increase 50% of the N & P.
