Yes it is a problem and one without a solution to quote one of my favorite statesmen

are more similar than slightly opposed moderates

yes it is nice to see a scientific eye backed up with a verifiable testing protocal

All tank combinations were run for both plenum And non-plenum systems

Considerable recourses were required to run the experiment for as long as it ran

If there was no significant change for 90 days ( the experiment ran for 121d) one would have to come up with a really good reason /idea to explain how or why a change would suddenly and spontaneously occur after all systems had reached a steady state/equilibrium for three months
Rob would have run it for years but resourses are limited
I think its cool he managed to work in some tanks with live critters
