okay as long as the water is pre-filtered so as not to crud up the media.

i called seachem today and spoke with them for quite a while. they seem to think the gravel i put in my first filter had some crap in it causing the crazy numbers in nitrite and nitrate in my effluent.

i went ahead and dumped it out rinsed it real well. i added a liter of denitrate and about 1 1/3 liters of matrix. its flowing just under 10 gph. i may try to get the flow higher but im going to leave it for now.

i asked them specificly if a tank can have too much bio filtration. she said absolutly not the more thats there the better off the tank will be.

ill prolly pick up some stability and dose for a week as they reccomend. they said its not necessary but it would speed up the process.

I wasn't talking about the volume of media, but rather the different filters. John Strawn of Aquaripure once reported that one of his customers couldn't get his new aquaripure filter to work because he refused to discontinue his other previous bio-filter - so the aquaripure filter never cycled. May or may not be an issue with this media at these faster flow rates, but is a possible consideration.

they knew my exact setup. they encouraged me to use everything i got and said it would all work well.

anything from aquaripure i take with a grain of salt. its this guys claim to fame so hes always gonna find a reason it didnt work.

we shall see if i get anywhere or not. so far im gaining on it with more water changes less feeding and added plants. i was 20-30 ish nitrate today

Actually it makes sense when you think it through...if you have an established bio-filter in an established tank, it's already handling all of the ammonia and nitrate there is...right? So add another bio-filter, but there's no ammonia or nitrite for the aerobic bacteria to further colonize...and without the aerobic bacteria to use up the oxygen in the conventional denitrate filter, the anaerobic bacteria don't develop to process nitrates either.
Much like live rock, even Matrix/de*nitrate rely on aerobic bacteria on the surface of the media to deplete the oxygen so anaerobic bacteria can develop within the pores... so you see the potential catch 22 here. Seems logical that one big bio denitrate filter is better than numerous separate ones.

yeah ive followed that ongoing discussion for quite a while now. hopefully your filter gets working soon.

Just a quick update, Following some flow problems I discontinued the secondary sponge canister so the flow is just through the Matrix/De*Nitrate canister.

How goes the good fight AD? Im assuming as a direct correlation my panda cories in my 20 long all died after a couple weeks of not getting their routine seachem prime dose. Just leads me to wonder if youve had further success in the last couple weeks

Hey Beetle - thought I lost ya! welcome back to nitrate city

Well, your post prompted me to test the effluent which I haven't bothered doing in a long time. While I'm waiting for the results, I'll recap.

To make 'good' water for water changes, 1) I setup a 10g in the garage to filter water using the Fluval Lab Series Nitrate Remover. This gets my off the chart well water down to 5ppm nitrates; abd 2) I also make deionized water using the API Tap Water filter. The DI water requires minerals and pH balance so I'm using Seachem Replenish and Neutral/Alkaline Regulators. I mix these 50/50 to do a 10g weekly water change on my 60g tank.
In order to facilitate the reduced volume water changes (which have been in effect for 3 months now) I am periodically using activated carbon and Seachem Purigen. I also have a pouch of API Nitra-Zorb in there from time to time to keep nitrates at bay. To ensure ample trace elements, I'm adding Seachem Fresh Trace with each water change and am [still] using Prime here and there.

Okay, the timer rang and the effluent test is in and it's 10-20ppm, so there is little indication that the bio denitrate filter is handling nitrates. <colorful adjectives go here!> I believe it's handling ammonia and nitrites...but anaerobic bacteria are being stubborn.
I'm going to cut the flow back to mere drips and see what happens in time.

So I haven't given up, but this is far from the slam dunk I hoped it would be.

sad story :( worse still, in the last few weeks im racking up the list quickly of fish that cant handle the nitrates. Lost all of my new green tiger barbs after a few months in my 110g (had temp problems too, though), all of my panda cories bit the dust in a similarly timely fashion in my 20g, and I have a missing BN plec. Oh, and my flying fox wasnt more than a year (or less) for this world. Im sure there are alot of factors playing in, but it seems suspect that within a month of no longer dosing prime every other day in my 20 long my cories start dropping like flies...

fortunately my cichlids are all doing well, especially my 110g with my rotkeil efaciatus in my watery acid (I decided that below a PH of 5.5 its watery acid, not acidic water )

but never the less, thats a shame. Im still torn between just finding fish that can handle the chemistry and setting up a second tank in the other room, as you did, to filter the water before using it.

Have you seen a decrease over time in effectiveness with the lab series nitrate remover?
