Seachem NITRATE REMOVING FILTER MEDIA DENITRATE 500 ML Seachem NITRATE REMOVING FILTE

any body ever use this stuff?
does it work?

my nitrates are like 80 ppm after a 50% wc this is disused here http://www.monsterfishkeepers.com/forums/showthread.php?t=211290 i

wonder if this would help?

i think once i get my nitrates down to 20-30 ill put 2 l in my canister

OOo I have the exact same problem. I still have nitrates out of control on a lightly stocked and heavily over filtered 55. The problem stems from 30-40 ppm nitrate from the tap. Thanks for the find im gonna try it out.

If your nitrates are at 80mg/l after a 50% water change, you need to get rid of fish, or get a bigger tank, or clean more often. No amount of "denitration" media will solve that problem. Fathead minnows (commonly known as rosey reds) show physiological problems at 21mg/l of nitrates so keeping your nitrates under 20mg/l only makes sense.

Please do not tell me you drink that water! 20 mg/l is the most that anyone should drink!

dude check out the link i put in the first post

every thing you said is true and i knew someone would say it. so thats why i added the link. so link it up

im just looking to see if any one has used this before does it work?

It appears it only works as an anaerobic denitrifier if you have less than 50 GPH of flow over it. Is there even a filter on the market that slow ?

Did you miss my post entirely It comes out of the tap at 30-40 . I suspect the OP is in a similar situation. It has nothing to do with maintenance I do more than my fair share. I could do a 100 % change and have 30-40 ppm.

lol, yup

Even if the OP had 40ppm out of the tap and he did a 50% water change, then he must have had 120ppm of trates before the water change... Which, assuming he did the same 50% change the week before, meant that he had a gain of 40ppm a week. Over stocked.

Anaerobic conditions can be achieved at any flow rate, but there just cannot be any oxygen present. The reason for the slow flow rate is so that the oxygen may be used by aerobic bacteria so it is oxygenless for the anaerobic bacteria.

You would really have to DIY to use this stuff to it's full potential

There are, and actually, you need a flow much slower than that, just about 5 gph. Basically a very small pump with a control valve to get the right amount of flow through the bio media.

These filters work very well but can take months for them to mature. Feeding with a special drink , not sure what it is, will help speed up the process.

You CAN do this with a canister filter. Many put the canister on a timer. Not sure how long the canister pump will last doing this though. They have had good results.
Another thing you can do is create a filter and have a "T" fitting in the output of the canister filter with a ball/needle valve to a filter strickly for nitrate removal so you don't need to add an extra pump.

The larger the media concentration, the faster the flow. You can have a 100 GPH, but I think that you would need over 100 liters of media. Don't quote me on that. I have to look again at the bio volume verse flow rate. I am not using my contact time chart either, that just didn't produce the results I was looking for, but it was a good try.
