Re: Aquatic Plants Digest V3 #1362

Originally I placed my Eheim diffuser/reactor at the bottom near my canister
intake.  I then read in Aqua Journal Vol. 33 that this specifically should
not be done so I moved it to the bottom of the tank on the other side away
from the canister intake.  Unfortunately, Aqua Journal did not give any
reason for their recommendation so one can only speculate as to the validity
of this suggestion.  Personally, I have not noticed much of a difference.
The only reason I can think of for the recommendation would be that the
return for the canister is near the top (at least in my tank) and the CO2
should be injected near the bottom.  Since the article also suggests using a
power head to increase circulation, I do not think the author is worried
about the adverse effects of the circulation induced by the canister filter.
In fact this statement seems to support my thought that the canister return
may be to high to adequately circulate the C02 near the bottom.
