Dosing correctly

Tank specs:

20 Gallon Tank
65 Watt Coralife 6700k compact light
Marineland 200 bio filter (up to 40 gallons)
Red Sea CO2 cannister w/ venturi
Flourite Substrate


Red Rubin Sword
2 Bunches of Moneywort
2 Bunches of Cabomba
1 large bunch of anacharis
Amazon Sword
Ruffle Sword
Marble Vals
Dwarf Tennellus - currently dying

Currently, I'm dosing with liquid ferts: Flourish, Excel, Kent Pro plant/freshwater, Flourish Trace and then nitrogen, and potassium every other day. I also have root tabs.

I dose Flourish and The Kent supplements 2 times a week and then potassium, nitrogen, and trace 3 times a week.

I bought some dry ferts from Aquarium, but thats why I bought a test kit for iron, and phosphate, and KH/GH... currently I have a GH of 14, and a KH of 4 - which I believe is good. High gh is good from what I have read. I change 30% of my water each week.
nitrates were at 20ppm and my nitrite and ammonia was at zero. Ph was at 7.6.
I tested for phosphates and tested a .1ppm, I believe I need .5 to 1ppm. I do have a little algae on the glass and some of the green leaves of the red rubin. Iron is at approx. .1ppm as well.

I inject CO2 with a red sea DIY kit. I just added a new batch, but I did not use wine yeast, because I could not find any. Anybody know where I can get some? I have dominicks, Jewel, Target, and walmart by me. I do not have a drop checker, but I do have a red sea plant lab kit, but I have heard these do not give the right results.

I have an african dwarf frog, and three smaller fish.

I do not know really where to start with the fertlizers... I bought KNO3, KS04, MgSO4, and CSM+B. This is what Alan said I should get since I am testing. He said possibly phosphate, but I decided not too since I have some fish, which he said I probably have enough phosphate. I will test to make sure. Should I add based on testing? I have read a lot about the EI method and other methods, but I am just not sure where I should really start. Hopefully I can get some direction. Thanks.

Well there a couple of versions, EI, PPS-Pro, then variations.

So it is kinda up to you, EI uses large water changes weekly to reset the fert load, PPS is more of a just what the plants need type method w/o large water changes. Obivously EI is more of a proven dummy system to get you started. Personally everyone is going to make modifications to either method to fit there specific tank(plant and fish load, ect..)

Its prob best to read up on all these methods, then pick one and modify to fit your needs/tank. Like you could start w/ EI dosing, then if you dont want to do as many WC's, cut back a little on the ferts at a time, cut back on the WC amount,wait a couple weeks and note how the plants react, ect.. Then continue cutting back with ferts and WC amount.

Since you have some test kits this should be OK, but just know that not all test kits are accurate, it would be good to test with a known/calibrated source just to be sure.

You seem to be pretty much on track. Patience is a virtue. This is the best link in the entire world for dosing:

I think I need more CO2... one liter is not enough. My CO2 levels are not at what they should be.
