a little CONFUSED - HALP!

So I'm setting up a DWC and connecting all 4 TUBS together.

If the tubing attaching all 4 tubs together isn't exactly the same height is that okaY? the difference in height means it'll raise the water by that difference?

As long as all of the tubing is lower than the water level you will be ok. The important thing in keeping the water levels the same in all your buckets is that the buckets are all level on the ground. If not the buckets that are lower will have a higher water level and vice versa.

thanks bro youve been repped
