bromie88;2724173; said:im told canister filters become nitrite factories because the water moves too quickly over the media in the canister, which doesnt allow the BB to do its job properly. even if you fill a canister with LR it will still produce nitrite, unless regularly cleaned. sometimes twice or more times a week is nessisary*
internal filters are a bit more annoying. there isnt much info on running an internal in a SW aquarium. i think is because by the time an aquarist wants to keep marines, they normally have done away with internals in favour of more 'advanced' forms of filtration, ie. canisters and sumps. so they use their existing equipment and modify it to fit the needs of SW. even though the main form of filtration in marine is as basic as it gets. using live rock and water movement. ironic really...
so i cant say for definate why, or even if they become nitrite factories. i imagine that its going to be the same story as a canister, but maybe to a lesser degree. as long as there is a cleaning routine.
ive run a fluval 4+ internal on my sw aquarium since it was classed as marine 6 months ago, as it was brackish for quite a while before. ive had no problems that seem out of the ordinary for new SW aquariums. a bit of algae, diatoms ect, but thats expected, and its all calming down now.
maybe when i set up my sump/refugium i'll be able to see the bigger picture but up to now im not sure. i think BigGourami runs a smaller fuval on one of his nano tanks. a 2+ i think, he's been doing this a lot longer than i have. so we had better just see what he says about internals in SW.
and id leave your HOB's on your tank. they'll be fine.
I didn't get the first part but the 2nd part was taken in
Thanks!
