Fast ? You got what for air? CO2 or exchange? Alot of plants intake more or everything....... Air/food/water.......... Mainly AIR.. I know it's hard to make CO2levels beyond top end...... Let alone above optimum levels,, what 1500 ppm..
I been using exchange air forever... which isn't a very high level.. What 300 ppm? something... But I've always entertained the idea of bringing in some extra CO2 and cut back on exchange.. But it works for me.
If you hit a roadblock with the sump pump, I designed an awesome little mod for Active Aqua 160gph and 400gph pumps that converts them into sump pumps. I use them in my reservoirs and they suck out damn near every last drop which makes them great for weekly res changes. They might be helpful in your arrangement. You'll need to find someone in your area with a 3d printer, but the parts can be printed fast and cheap.

That’s pretty sweet, what type of filament do you use? I’ve read a lot about bacteria in 3d printed parts (for food applications) due to the extra ridges and gaps. Have you had any issues? Do you do anything to prevent this?If you hit a roadblock with the sump pump, I designed an awesome little mod for Active Aqua 160gph and 400gph pumps that converts them into sump pumps.

i use PLA and haven't had any issues with printed gizmos in my tanks. I wash all of my plumbing pieces between rounds so everything gets a wash in water and dish soap, but that's all I do. I use synthetic nutes with a twice weekly compost tea inoculation. I use this pump in that too for added agitation.
As to health concerns, filaments aren't made for food applications, though I've seen cookie cutters on thingiverse so clearly people are throwing caution to the wind. Also, printers generally use cheap nozzles made of soft brass. IDK if the nozzle manufacturer in China uses a packaging oil on the nozzles or not, so there's that to be concerned about as well, but perhaps over time at over 200º C, those oils sneak out with the filament flow, but I've not yet attempted to mix my prints with my food.
Edit - Those Halos are adjustable, so you can render various sizes. Install OpenSCAD, then open the SCAD file, locate the variables up top and change the numbers around as you want. Press F6 and that will render the size you want. I just made mine for the 1 gallon pots, I think #3?
Ever think of a passive central wick-type grow? The first form of 'hydro' I ever did,, was a towel stuffed up into the bottom of 5-gallon pot and the other end hung into a reservoir for the wicking up water. Every once in awhile dump 5-10 gallons of water in the res... Got to be the simplest way of constant water. No pumps no nothing,,, cept a bubble stone wood be nice.........
