Hello
The NO2 is gone (oops it spiked again) now I can start phase 2 of the redesign of my tank - get the plants to grow like mad and remove the algae.
About the tank:
Things I had done include:
Things I could do:
Before cleanup and Sundays water change:
What should I do to get the plants pearling again?
What should I do to get the tank free of algae?
Regards,

The NO2 is gone (oops it spiked again) now I can start phase 2 of the redesign of my tank - get the plants to grow like mad and remove the algae.
About the tank:
- Volume: 30l Dennerle Nano Cube
- Size: 30x30x35cm
- Light: Dennerle Nano Light 11 W
- Substrate: Sand with some clay balls
- CO2: yeast DIY with CO2 dome and a Dennerle drop checker
- Filter: Dennerle Nano corner filter
- Fertilizers: EI 30g KNO3, 5g KH2P04 mixed with 500ml, dosed 4 times a week 5,5ml (2 times a week because the lack of uptake by the plants). 50% water change once a week with one dose of easy-life ProFito for traces.
- Plants:
- Hemianthus callitrichoides 'Cuba'
- Cryptocoryne spec. "Flamingo"
- Ceratopteris thalictroides
- Rotala rotundifolia
- Fishes:
- 8 Corydoras hastatus
- 8 Hyphessobrycon amandae
- Snails:
- 4 Clithon sp. (diadema) souleyetana
- 2 Neritina natalensis
- Water parameters (changed water after testing because of the high NO2):
- 27° C
- 238 µS/cm2
- 4° dKH
- 5° dGH
- 6-6.5 pH
- 0.05 mg/l Fe
- 0.2 mg/l NO2
- 10-20 mg/l NO3
- 3-5 mg/l PO4
- 3.5-113 mg/l CO2 (drop checker 80 mg/l CO2)
Things I had done include:
- Added one Ceratopteris thalictroides and 3 Rotala rotundifolia
- Added more CO2 by getting more washed in to the water with the current from the filter and a bigger dome.
- Added a max 660 l/h or 175US gph powerhead to get more current.
Things I could do:
- Adding epsom salt.
- Adding a second identical filter.
- Adding a second identical light.
- Building a CO2 reactor out of the powerhead or get a other one as this one maybe to strong.
Before cleanup and Sundays water change:
