alternating day macro/micro vs all in one solution

[jimwalsh]

is there an obvious disadvantage to using an all in one mix vs macro/micro mixes?

I have built a dual peristaltic pump and would like to automate dosing, but would have to shift from using macro and micro mixes and liquid carbon, to all in one and liquid carbon.

using EI principles is it enough just to get the excess into the tank by any means?

There is no difference. Use whatever method you want for your needs.

thanks mate thats what I thought...

it does beg the question

why make two different mixes up? surely its just easier to have the all in one mix

 

[ceg4048]

Because people do not want to buy Ascorbic acid and mould inhibitors in order to make up the mix. That increases cost. They just want to keep it simple and buy the minimum. It cost's nothing to dose on alternate days.

thanks for that

I already had some of this stuff so no extra expense until it runs out.

I approve of the thrifty sentiment though...

Quite a few people have managed to miss mix their all in one and either have their all in one go mouldy or the iron precipitate out. Just need to be slightly more careful when mixing all in one compared to just bunging it in for two part ferts.

This is the definitive reference.
James' Planted Tank - All In One Solution

Note that might be worth testing the pH of your solution, to verify it is correct and keep it away from light.

thanks buddy much appreciated the mix will be sitting in the cabinet so no worries with light.
