I have hard water of 150. If I am not mistaken, MGS04 is dosed only if you have soft water. Is this correct?
Laith said:I like this calculator. One question:
For 55g of water volume, the calculator indicates 38ml of TMG per week (or 33ml without the EI option ticked) to aim for a target level of 0.5mg/l of Fe...
The TMG calculators I've seen online (for example: http://www.fishfriend.com/fertfriend.html) indicate that 38ml of TMG will add 0.133mg/l of Fe (and 33ml will add 0.115). Is that calculation wrong?
Edit: actually, I just noticed that changing the desired Fe target level doesn't change the TMG dosing; only the CSM...
What about Iron Chelate 10%?
If I am dosing CSM+B to the spec's of the calculator under EI, would I still dose Iron Chelate 10%? If so, could you please add a line for this in the calculator?
czado said:Very nice. TMG calc will be a nice bonus -- fwiw, if I do one, I'll share the code and see it matches the FertFriend. TMG is 0.07% (g/L) Fe.
Is it alright to spread that link around?
For what its worth, my CSM+B calc says it would take 17.701 mLs to reach .50 ppm Fe in 50 gallons, using the trace mix of 40770 mg (9 teaspoons) in 500 mL. Your calc says 2.78mLs (.556 teaspoons) with EI dosing turned off.
czado said:No you understood it: I see now the 9tsp of CSM+B in 500mL is a TMG approximation. Still, .556tsp CSM+B dry in 50gals is 0.873ppm Fe.
I think these may just be rounding errors from the 100gal example the calcs are derived from, and it is a great great calc for EI approximation. All this is just for whatever its worth.
Just throwing it out there: Up for collaboration with anyone who wants to maybe make the "calc for everyone" Tom Barr has suggested.
