Using RO water with Blue wizard, need water change, do I add Blue Wizard again?

 

I have a 22 litre tank with RO water

 

I am currently cycling my tank, was using a plant fertiliser and it says to add every week but recommend 25% water change

 

if I take out 25% water do I have to add 25% Blue Wizard? 

 

(It was roughly 5 pumps to my 22 litre, so if I removed a quarter water, do I add RO water with 1 pump of Blue Wizard?)

You need to remineralize to a specific TDS or gH/kH.  Just pumping the remineralizer in isn't the proper way to do this.  

 

Essentially the parameters you setup your tank with to start with are typically the parameters you want.  So when you do a water change you change use water with those parameters.
