I know baked! Sounds like his and mine share some similarities. Mine is a more straightforward 4 tub 27 gallons each RDWC, so not quite like a flood table. Mine has an enclosed lid, flood table doesn't.
Ya his tables come with tops he drills 5 inch holes in em for net pot to sit in then the roots dangle from those to the water but il get him in here you guys can chat it up he's a good dude
Much respect

I get the table tops...they are available for all
botanicare tables. I run 2 x 4 tables and some 3 x 3 tables with lids. I use a 3.25"' hole saw to make my holes. Plants are then put in 3.75" net cups filled with hydroton/clay and just set in table lids.
Here is a pic of an under the lid peek...
This is a 2' x 4' table...
This is a shot while cleaning out the table....typical root ball from a 2 x 4 table....continuous flow
If his flood table has a lid, then just continuously running the fill pump and letting excess water drain back through the return/overflow will oxygenate the system just fine. I've heard about issues with trying to oxygenate a 'dead reservoir' style ebb n flood, but I bet they would be solved with a continuous flow approach.
One thing I would change if I were to run this is that in my ebb n flood trays, the inlet and overflow are right next to each other. I'd relocate one of these to the opposite side of the table, so water would flow across and ensure all plants see fresh nutes.
Here are some better shots to understand for ya...
from outside here is the table with a roughneck under it...notice the 1/2' and 3/4' hoses...one fill one drain...this is a 3' x 3'
Botanicare table...with a 31 gallon Roughneck.
this is what's going on in the ressy... 396 gph pump running
this is what's going on inside the table...if you look at the first pic here...on the right is the drain...the left is water pumping in...now since they are side by side to aide in making sure it's all mixing well I cut a little piece of 1/2" hose and put a 1/2" 90 on it to ensure the pump fires at the back of the table and drains forward. The hoses being up front and side by side just simplifies the water changing process and cleaning for me...
A rather simple design...but effective for me!
I saw what you said about putting the inlet and the drain on opposite ends...in the perfect world this would be great. I have ran that way having an attached line out of reach is a pain. The cleanup in between runs became a pain also....cuz I like to clean all lines out in between runs. I solved my mixing issues with a bent 90 shooting at the back of table...while the drain is in the front...check pics. Really simplified everything for me when I put them together like shown...
I would like to see the pics of your design....I have made many home made designs over the years...it sounds similar to one I have built before...but I would like to see pics. How are you draining back to main tub?
