CSM+B Iron dose
If I dose 1/8 tsp of CSM+B to 5 gallons of water, how much iron did I add to the water? I can remember being able to calculate this myself, but I was younger then.

Re: CSM+B Iron dose
That's why I use calculators.
You're adding 1.85ppm of Fe. You're way above any dosing methods.

Thank you!! :smile: I couldn't find the calculator I used to use. Now that I have a number I can adjust what I plan to dose to a reasonable amount - I haven't dosed at all yet.

Re: CSM+B Iron dose
Have I made any mistakes in figuring this out?

--CSM+B trace mix solution--

8 fluid ounce bottle, 236 ml of water

Each dose to be 5 ml of the water and CSM mix.

236ml divided by 5 ml equals 47 doses in bottle.

Tank to be dosed holds 5 gallons of water.

1/8 tsp of CSM+B in 5 gallons of water = 1.85 ppm of iron.

Desired iron concentration in 5 gallons is 0.2 ppm of iron
0.125 tsp x 0.2/1.85 = 0.014 tsp of CSM+B per dose
Total CSM+B = 47 x 0.014 = 0.64 tsp of CSM+B (5/8 tsp)

Add 5/8 tsp of CSM+B to 8 fl oz bottle
Fill bottle with tap water, and shake to dissolve.
Dose 5 ml of solution at a time.

My tap water ranges from near zero to .027 ppm iron, so it can be ignored.

Re: CSM+B Iron dose
My calculator validates your conclusion.

Re: CSM+B Iron dose
I guess if your using CO2,then Iron might not be needed. But for all other setups,aquariums,aquaponics and maybe hydroponics..I tell you gluconate Iron drives plants wild. Seen it with my own two, and half the time four eyes. Glasses.

One more,maybe more than the dose on the bottle is needed for a heavy plant growth. Still,fish are fine and happy. I'm even thinking its healthy for them. Gives them energy.

Re: CSM+B Iron dose
Oh, check if you have phosphate in your tap. We know what it does to Fe.

Re: CSM+B Iron dose
My city water isn't checked for phosphates. But, if it had more than a trace there wouldn't be that much iron in the water. Iron would precipitate out.

I looked at my supply of CSM+B and it looks like I added enough iron to it years ago to double the iron in the mix (as I vaguely remember it). So, I'm not sure how much iron is in the mix. I just bought a small bottle of Flourish Iron from Amazon to use instead. I'm much more confident that it has a knowable amount of iron.

Re: CSM+B Iron dose
Now about .378ml of Flourish Iron to reach .2ppm

Tough to measure, need a small (1-2ml) graduated cylinder.
