Eheim filters

[desdre]

Hello,I have a 72 gallon marine tank with 2 damsels and getting an
Emperor Angel in a couple of weeks and was wondering,i have a fluval
304 on my tank with a prizm pro protein skimmer amd 40 pounds of live
rock and my problem is my high nitrates (40 ppm).I cant seem to figure
out the problem.I was thinking on upgrading my fluval to and Eheim 2217
filter that goes up to 159 gallons.So im going to run both but with the
new filter do you think it will bring my nitrates down?Thank you.

coming from a newbie, but here goes...

Canister filters = nitrAte factory... get rid of it, and you'll notice a
considerable difference....

All biological filters are per definition 'Nitrate Factories' because the
sole point of having a biological filter is to convert ammonia into nitrite
and then nitrite into nitrate. Ammonia is very lethal to fish, nitrite is
somewhat less lethal to fish but will still kill'em, but nitrate is
relatively harmless to fish but should still be removed via water changes or
heavy planting (whish will use some of the ammonia and nitrite directly by
the way...)

Biological filtration is VITAL when keeping fish unless you are doing very
heavy water changes / continuously water changes...


Some fish are more resistant to ammonia / nitrite but they will all die if
the concentrations gets to high...

before spending more $ on filters
try doing more frequent water changes & more frequent cleanings of your filter

the real mistake you made was forgetting to ask how much LR he has.

if its a FO he should live with it, or follow the responses to your post :) if its a fowlr
or reef you are correct.

"All" should have been most, most filters that encorporate biological filtration only do
nitrification (create nitrate) while there are several that do denitrification also, more
so sw tanks have the advantage of being able to get denitrification from LR and a DSB
these are both biological filtration, in that they use bacteria to process waste.

heavy planting is good but doesnt work all that well for most marine tanks, not to say it
doesnt work its just usually more of a pita than its worth.
