[DWC] Changing the reservoir under scrog net

[kubat]

Like the example in the photo,

I wanna change the reservoir every couple of weeks to reduce salt build up, but looks impossible to do so after i place the scrog net.

Got any ideas? Is it really necessary?

If not which topping off method you do and why?

Thanks. Luv u all.

There is a grower on Nirvana's weed portal that built a setup so the lids are attached to the nets and he lifts them straight up roots and all. My solution was piping them together and making a RDWC setup. That works very well but if I do another system I will use flexible tubing instead of ridged pipe.
In DWC I made nets that attach to the bucket lids and so they were independent and I could change the water every week and check the PH every day
