I know that you cant mix macro & micro together in their concentrated state, but how much water is needed to keep them from reacting to one another? Since its recommended to does just before the lights come on I was thinking of using an Aquaclear 20 I have hanging around as a make shift dosing pump since Im normally at work when my lights kick on. Basically I'd have the aquaclear on a timer to be on a little before lights are on and turn off later with the lights. I would then dose the filter at night for the next days use. I would be dosing 5ml of each a day, so would that work without creating a disaster?
