i'm sorry that i didn't see your thread earlier.
you've correctly identified the weak point of the system.
most of us who have run into it have ended up doing several things to resolve the issue.
for next time:
1. increase the size of your return port in each bucket to 1".
2. put two return ports in each bucket.
3. run a larger diameter pipe (3" or 4" PVC or ABS) down the middle of your buckets sloped towards your reservoir. drill holes in the top of this and only use shorter lengths of that 1" hose from the buckets into the larger pipe. when roots get into the hoses, they'll be easy to clean out.
are you going to run it live or sterile?
also, it looks like your the water level in your buckets is low. depends on the depth of those baskets tho.
live or sterile, are you going to use beneficial bacteria (live) or H2O2, bleach, or a product to kill organisms in your water (sterile).
are you chilling the water? how have your roots looked in the past? pics?
