How many plants enough for EI?
I am starting up another planted tank, making it amazon themed and using cuttings from my other tanks. I want to avoid the algae and other problems I encountered with my first planted tank and part of the remedy for that was getting my ferts correct. However, I do not know if I currently have enough plants to add ferts per the EI method. If I do not, what method would you suggest?
specs: 20 gal long, eco/tahitian moon sand 50/50 mix, DIY champaign yeast co2 1 gal jug and ceramic airstone, about 2.5 wpg. Up and running for 2 months approx.
plants: 2 SMALL swords (i trade them out when they get too big), 1 med and 1 large jungle val, 4 small pennyworts, 1 chain sword, 5 or 6 stems of cabomba, and some moss. I want to thicken my cabomba but I want to see how it does in this light first as it may be a little too low. I have a better light I can use but I know apistos don't really like really bright light. Not sure if I'll stick to this lower light or diffuse brighter light via floating plants. I would also like to add more amazonian plants.
My fert program for my other tank uses dry macros in the form of P2O5, Nitrate of Soda (16% N with calc carb), and muriate of potash (60% K2O).
My micros are in the form of iquid flourish. I can add what's in flourish but I'm pretty sure most people already know that :-). From time to time I'll also add liquid iron but I still don't know when to tell when I need it unless my plants show signs of iron deficiency.
Thank you in advance.
