Flourish EXCEL and Flourish Comprehensive???

I have a 20 gallon moderately planted:

2 red indian swords
1 banana plant
1 small young clover patch
10 onion grass plants

I Do NOT use CO2, have flourite substrate, fert tabs under the plants when first planted 2 months ago. I am running 65 watts (raised about 6 inches from top of tank) 10 1/2 hours a day (started at full 12 hours but got a plague of green hair algae) Currently doing 25% water changes weekly

I have currently been using Flourish once a week (just the plain comprehensive) and showing growth. Good growth on the swords (new leafs are deep red) and good on the banana plant. the onions and clover have not been as good. my initial clover patch i planted is barely holding on but a runner shoot off that is coming around much better.

How should i be fertilizing? I'd like to start with EXCEL because i dont use CO2 but dont want to over do it. should i work up to a daily dosing with excel or just jump right in using it regularly with Flourish? I would also like to up the flourish to twice a week, but again dont want to do too much at once? should i up water changes with added fertilizer or would that just cancel out added fertilizer?

thanks for your thoughts and pointers

With the amount of light you have your plants need macro nutrients - NPK, as well as the micronutrients provided by Flourish. You can use Flourish Nitrogen, Flourish Potassium and Flourish Phosphorous, or to save a lot of money you can use potassium nitrate and mono potassium phosphate for the macro nutrients.

Flourish Excel is a carbon source, and with that much light you probably should use it too. All of the Flourish products should be dosed per the bottle directions.

Should you want to use Seachem's ferts, there is a Seachem fert calculator that you can use that is based on their recommended dosing schedule. Post #4 has dry fert conversions. Also, Seachem has calculators for their plant products on their site.
