Hi

Hopefully in the next week or so, i should have all the bits i need to start injecting CO2. Once set up, i want to dose using EI.

I have read posts regarding dosing until my head hurts. I must be a bit dim! :oops: I understand the concept, just not the math!

If someone could work out the dosing required for a 620 Litre Aqua One 1800 Bowfront, (210 watts lighting total) i would be most grateful. I have all the required powders from AE, but every time i look at a dosing calculator, my brain turns to mush! :oops:

Any help would be gratefully recieved!

Thank You

Mark

Hi,
The baseline "reference" dosing for a 620 L tank is as follows:

3X per week 2 teaspoons KNO3
3X per week 1/2 teaspoon KH2PO4
Optional - (Depending on tap water) 3X per week 5 teaspoons MgSO4 (this can be scaled back)
2X per week 3/4 teaspoon Trace Mix or 41 ml TPN

Cheers,

Hi Mark,
FYI water can be hard without having an ounce of Mg, however your water report does show an 8 sample mean value of 19.85 ppm Mg so you can easily delete the MgSO4 dosing. :D

Cheers,
