Mixing ferts in bulk - Aquarium Advice

SparKy697 · 01-03-2007, 08:49 PM

I have gotten some great advice on feeding ferts. I still have a couple of questions that I have yet to find in my reading and talking to others.

1 - is there a shelf life with mixed macros or the csm+b?

2 - I have brown bottles just in case light is an issue. Are there any other storage concerns that I should be aware of?

Not sure if there's a shelf life, but I personally mix mine in 2L containers with markings on them, and I fill to 1.5L. So I make 1.5L batches each time I run out. Also, the only one you need to worry about light is the CSM+B, as the light will cause the iron to fall out of solution. Also, don't mix the macros with the micros, as one of the macros, I think it's Phosphate but can't remember, causes the iron to fall out of solution as well. But you can mix all the macros in one single solution. You just need to make sure you get them in proper ppm's for dosing. I do mine all separately for ease of mixing.
