Reservoir Change

[McLeafy]

I'm going to run an Ebb and Flow for the first time. I have a 55gal reservoir one control unit and 6 3.5gal plant modules. How often will I have to do a complete reservoir change seems every week will be a waste but maybe I'm wrong. Thanks guys!

in my opinion you don't need to, just buy a cheap air pump , a hose and a oxygen stone and put it in the bottom of the reservoir.
because i think that we only need to change the water because oxygen levels are low,but i'm not sure.

I run nft and change every 10 days max, clean pumps etc, don’t fill ur res up to start as the plants won’t need it, keep it at a level that the plants can use to save wasting nutes, as my plants get bigger I fill the res up more
