I'm going to take all my measurements tonight when I get home from work.
I can tell you what I have for equipment.
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
Plants:
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 fertilizer.com, 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 am almost positive my nitrite = 0, ammonia = 0, nitrates around 20 ppm, and ph around 7.8. It has been stable for months now. I change 30% of my water each week.
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.
