water changes and Ei dosing

I trimmed some of my HC or should I say pulled out a good bit.
I noticed my eco substrate is pretty nasty.
heres my question

I normally do my water changes on sunday,50% 1/4 tsp kno3 and gh boster plus 7ml of plantex 15 mil excel and 5 mil flourish trace.
If I need to do multiple water changes what do I do about my dosing?

Typically, a good, large water change following pruning/moving plants is sufficient. If you feel the need to do more, that's fine, too. Each 50% WC will theoretically halve the amount of nutrients/compounds in the water. Just use this as a guide and dose the tank accordingly (to the levels that you are shooting for). EI is meant to be flexible, so if you add a bit too much, you will reset the tank at the end of the week anyways.

There are some good calculators out there for more specific information about dosing ferts

When I find it necessary to do more frequent water changes then I do this every third day. So I do a water change and add my macro's. The second day I add my micro's. The next day I start all over again.
