So I'm using an EI dosing regiment for my 20 gallon tank, but I saw in another thread that dosing should be cut back for tanks that have low-medium light and/or reduced photo periods. I have a Finnex Ray 2 that's raised to low-medium light levels, but the surface of my tank is probably 75-80% covered by frogbit, which reduces the lighting levels even further. I also only use a 6 hour photo period. Does anyone think I should cut back on my EI dosing? I've only been dosing for about 3 weeks and haven't noticed any issues with algae although I think my ferts may have killed off my 2 ghost shrimp. The fish and plants, however, are doing fine.
