Just kidding. Here is a little info:
29 gallon
about 2wpg (ODNO)
EcoComplete
Ammonia: 0
nitrItes: 0
nitrAtes: 30-40ppm
gh 120ppm (6.7degrees)
ph: 7.0
kh: 80ppm (5 degrees)
CO2: 15ppm
Phosphates: ?????? (I assume they are high like the nitrAtes)
30% weekly water changes
Daily: ½ tsp Flourish Excel
twice a week: 3tsp Flourish Trace
twice a week: 3tsp Leaf Zone (3% K2O, 0.1%
Fe)
(3tsp in 29
gal adds 4.1ppm
K and .14ppm
Fe)
plants: Amazon swords (1 lrg, 2 sml), several java ferns, 3 tiger lotus, 2 small wisterias and some dwarf saggitaria.
Plant symptoms: older leaves develop yellow spots, yellow tips and brown holes. New leaves seem fine.
Algae: a little green spot algae, and a lot fuzzy gray algae (about 3/16ths in long). I’m guessing that when I fix the problem with the plants, the algae growth will slow down.
CO2: I recently started a
DIY CO2 system. I only have about 2wpg and dose Excel, so I am assuming that 15ppm
CO2 is plenty.
I’m guessing that I have a Potassium deficiency. I add Leaf Zone which is Potassium and Iron. But I’m worried that adding enough Potassium will add too much Iron - Adding only 8.2ppm
K adds .28ppm
Fe.
I’m thinking of buying potassium sulfate from Greg Watson. But the budget is tight so I want to make sure that potassium is the problem before I spend my hard-earned money.
What do you guys think?
