dialing in the ferts
After a year and a half I've finally accumulated all that I've wished for: 75 gal, pressurized CO2, 100% flourite substrate, and recently purchased ferts. Yesterday I put in $30 worth of stem plants in there. I already had a huge crypt, 3 struggling amazon swords, and some anubis.
Here's what I'm dosing (just started today, however):
KNO3: 1/2 tsp. (3x week)
KH2PO4: 1/2 tsp. (3x week)
K2SO4: 1/4 tsp. (3x week)
Magnesium Sulfate: 2 tsp. (1x week)
Flourish Excel: 1/2 capful (3x week)
I have Plantex CSM+B but haven't learned how to dose yet, so still using teh Flourish.
My known readings are thus:
pH: 7.6 (note: tapwater is also 7.6)
I increased the bpm on my CO2 to try to lower the pH.
Some additional info: Magnum 350 with CO2 run into the intake, Aquaclear 500, large piece of Malaysian driftwood.
Now that I have what I need, I need to know what to do with it so I don't screw it up. Please let me know what other info I can provide to give you a better picture. Thanks.
