Help me with dosing
After reading and re-reading seemingly endless posts on dosing, I think my eyes have gone cross. I know this is supposed to be easy, but I need help with a place to start my dosing! I'm not sure if you would consider my lighting medium tech or what, and I have a highish fish load. Here's my setup:
* 29g (30" long)
* 2x24w T5-HO Nova Extreme lighting (6" above water using the legs, 9 hours per day)
* Black hood on top of tank blocks some light to parts of top front of water column
* Marineland Emperor 280 filter
* DIY CO2 (About 1-2 bps)
* DIY Hagen Mini Elite Diffuser (in the mail...)
* ECO-Complete substrate
* 1x 4-5" Gourami
* 1x 4-5" African Spotted Leaf Fish
* 1x 5" Angelfish
* 3x 1-3" Tiger Barbs
* 2x Otos
* 1x Rubber-lipped pleco
* 1x Upside-down catfish
* Anubias nana
* Cryptocoryne parva
* 2x swords (not sure which)
Dry Ferts purchased from aquariumfertilizer.com:
* CSM+B Plantex
Sooo, I need to get a decent dosing schedule to start with as I get to know my tank. Would my fish load be considered high enough to require less Nitrate dosing? I'm confused if my setup is considered medium-tech or if I can dose 1-2x a week instead of 3x with less water changes. I'm willing to start with the water changes each week if need be, but I'm not sure that I will be able to keep up with this. I have Chuck's calculator and it tells me to add like 3/4 tsp K2SO4 if I am to achieve near a target 20ppm K, but that's way higher than any suggested dosing I have seen!
How's this to start? I could be way off base, but that's why I'm posting!
1/16 tsp - KNO3
1/32 tsp - KH2PO4
3/4 tsp - K2SO4 (way too much?)
1/16 CSM+B Plantex
How often should I dose with my setup? 2x per week, alternating macros and CSM+B? Can I get away with water change every 2 weeks? Thx everyone!

Reason: Added exposure time
