need Ei Help...

Can somebody point me in the direction for dosing macro nutrients recipe:

high fish load ... i think?
(5 bigger fish 5-6" approx. plec, 3 x clowns, 1 red tailed shark
40 approx. tetras)
275ltrs.
108 watts of light can add another 54watts if needed ?
co2 injection

(do i need to supply other info... i.e water hardness etc... )

i found this one on this site..... will it suit my needs...

60 – 80 Gallon Aquariums
+/- 3/4 tsp KN03 3x a week
+/- 3/16 tsp KH2P04 3x a week
+/- 1 tsp once a week (water change only) ( of what?).......
+/- ¼ tsp (15ml) Trace 3x a week
50% weekly water change

can somebody clarify +/- in this setup

 

Code:

Your fish load sounds okay now, but the redtail will get huge, not sure if you know that. 

My red tailed shark should only reach about 6" .... he's about 4" already... cant believe he was only the size of a small tetra when i got him

Code:

So you can go to about 2 watts per gallon. What type of lighting/bulbs are you using.

i have arcadia 4x54watts t5's 2 white / 2 blue at mo. i am using 2 white for plant growth, they are marine blubs, will be changing them as they expire over the next few months... any pointers as which bulbs to go for.?

Code:

How are you injecting/mixing the c02 into the tank?

i am injecting pressurized co2 into my eheim filter controlled via ph computer and ph probe.. set to ph of 7.05 based on kh of 11 = 29.400ppm

is there a benefit to to adding GH booster to my water changes.. i'm on the east london water supply... slightly hard water i think....

is a tsp roughly = 15gramms ( trying to figure out how much KN03 & KH2PNO4 to orded and how long it will last....)
