Re: Fluidized bed filter and the planted tank

Hi Sam...

A teacher once told me that the only stupid question is the unasked

As I understand it, plants make better use of ammonia and nitrite than they
do of nitrate. I would recommend removing the FBF from your planted aquarium
provided that you don't have an outrageous fish load. The FBF is very
effective at removing ammonia and nitrites from the water, both of which are
more useful to your plants. You could monitor ammonia and nitr*te levels
when you remove the FBF and do water changes to avoid spikes, but I don't
think you'll have any problems.

I had an FBF on my 90 gallon tank which I removed about two months after
planting to avoid starving the plants. (It now resides on my FO tank.) That
was about six months ago and I have only seen improvements in the plant
