Re: Aquatic Plants Digest V1 #270
I have a couple of comments to make after reading thru the past weeks
email (I've been at a conference - non-aquarium related).
Firstly, regarding Fe test kits:
I use Red Sea Pharms kit & found this works well - results
certainly correlate to amount of drops of Duplaplant24 daily
fertilizer that I add to my tanks. It is pretty cheap also.
I'd like to know if anyone has any comments regarding this
kit or know how it compares to the La Motte one (I read that
someone didn't like the Dupla one or something along those lines).
Secondly, regarding anaerobic substrates:
I've had first hand experience with anaerobic substrates. The
plants grow less well when the substrate is anaerobic than when
it is not. Vacuuming anaerobic substrates can kill your fish
unless your tank is well aerated.
