QUESTION

[dsuperman]

Thanks for the reply,i was wondering if there was an optimum in general. I also think faster flow would hamper biological but can't say for sure. Joe Gargas down in florida states that all filter media can be rinsed under any tap on a regular basis,that there is enough bio in the water and on the glass, even a barebottomed tank to replenish itself quickly. I don't do that, i usually have 2 filters in a tank,only rinsing one at a time.
