Pythium can effect any system. If you have an adequate amount of surface agitation both work fine. In a cramped site full of roots a waterfall may perform better but that's not because they are better. As far as heat both pumps give off heat but both are very low wattage so it negligible. Pathogens are everywhere what's the difference between spaying water through the said tainted air or using an airpump to force air through the water.... Same dam thing.I'm sorry but you are wrong about your misconception with waterfalls over air stones as I have first hand experience and are doing both actually and I would choose waterfall over airpump and my air pump is waaaay louder than the waterfalls are I can actually barely hear the waterfalls unless I'm in the tent and have the lid opened actually..Also bubbles themselves do not actually put d.o in the water it's when they break the surface tension of the water and mixes with the air....And my waterfalls kills my veg tent ...And pythim can happen even when you sterilize as it's in the air that a airpump intakes and then goes into your system.....And the bubbles makes ur pH fluctuate alot more than w.f....
How does an air pump make ph fluctuations? If you talking about shifting carbonic acid into bicarbonate form. That's directly related to gas exchange and bases in the solution.

Agreed half the watts will be close to half the heat.From what I have read is pH rises due to loss of co2 from the air stones...However I'm not totally sure but I know it happens also why current culture took the matala disc diffusers out of the epicenters...So I bet they would have a better answer for you...
I'm not saying air pumps don't work by any means as they do however everyone's setups and goals are different...There a million ways to skin a cat and or get d.o into a rdwc setup...Air pumps and water being the same in power well all depends on the pumps...As like the alita120 I have vs my x2 350gph h20 pumps my h20 pumps use half the watts and amps...Plus it's a hell of a lot louder it puts a lot more heat into the system vs having the h20 pump inline outside the totes...Replacing the air stones frequently vs not having to ever.... Just all depends on what your goals are and what your trying to do...
I have some experience setting up air systems in shops and have many years experience running fish rooms with more than 20tanks on single and multiple air pumps.
The biggest thing you can do to evenly provide air to each site is increase the volume of the system providing you have adequate room for flow so a loop effectively acts as that. Given the same size piping a loop will be superior to a single line. Often times reservoirs are put in where the runs are long to help aid but the best route is using larger piping. Now in a system that's constantly running volume into and out of the system is going to be much more important than total volume.
I don't think for your purposes the total volume will make much difference but it certainly won't hurt.
TLDR: an adequate pump that puts out enough volume to meet the requirements of the airstones is all that's needed. In a much larger system with a much longer run you would see more benefits.
Agreed half the watts will be close to half the heat.
CO2 strives for equalibrium like all gasses and the gas exchange just like with waterfalls happens at the surface primarily. Gasses like CO2 are a lot easier to dissolve in water than o2. But the only way I could see any difference is if the air pump was located in a high CO2 area bringing CO2 into the buckets and that would lower the ph. When you create gas exchange the water tries to reach equalibrium no matter how it's achieved.
Did they replace it with a waterfall or just delete from the system?
Yeah it was probably found it was not needed and they could reduce costs.... Hopefully passing some of the savings on to the consumerThey just removed it from the system although the return line goes into the epicenter so it's waterfall still like it was...
