Migration to EI dosing low tech

[drjack]

Hi, after struggling to succeed with CO2 I have migrated back to a low tech tank. I have read the articles on EI dosing for low tech tanks. I have Green Spot Algae starting to devlop so I wanted to deal with this quickly. My set up is as follows:

Tank: Juwel Vision 180 with 140 litres/ 36 US gallons water.
Lighting: Medium: 2x35W T5 tubes 8 hours/day = 2 watts/US gal
Substrate: Caribsea Eco-Complete
Filtration: Juwel supplied Bioflow 3 internal (1000 lph) plus Eheim Ecco pro 200 external (600 lph)

EI Dosing Weekly: KNO3 5/16 tsp : KH2SO4 5/32 tsp plus Seachem Equilibrium 5/8 tsp weekly

Fish 40: MostlyTetras

Plants ~ 100+
30 Crytocoryene Lucens, 10 Cryptocoryene Wendtii Brown,
1 Echinodorus Ozelot, 1 Echinodorus Uruguayensis, 1 Echinodorus Vesuvius,
20 Ludwigia Repens Rubin, 4 Hygrophila Difformis, 12 Limnophila Sessiliflora,
3 Microsorum Pteropus Windelov, 4 Aponogeton Crispus Red,
2 Anubias Congensis, 12 Limnobium laevigatum

I have 2 questions: Does my EI dosing look right for this size tank and amount of plants and would incresaing the KH2SO4 deal with the GSA?

Aay advice really appreciated,
Best Regards, David

Hello,
FYI K2SO4 ( potassium sulphate) will never solve a GSA problem. GSA results from any combination of poor CO2 and poor phosphate (PO4). If this a non enriched tank therefore it's suggested that you dose KH2PO4 (potassium phosphate).

Cheers,

Great, thanks for the correction, I will do that.
Many Thanks, David
