Aqua World no longer is making their nitrate filter

Recommended Posts

I have been told by Shirley Aquatics that Aqua World is no longer making their nitrate filter. This is such a bummer because as far as I know it is the only tap water nitrate filter that takes nitrates to 0, is rechargeable and is made for the aquarium user. Shirley Aquatics told me they sold lots of them so they were disappointed that they are no longer being made either.

If anyone knows of others, please post as for some people with super high tap water nitrates there just aren't any other viable and fairly simple/easy solutions as this one.

I had done some research on this a few months ago when you were ordering them from the UK. I wasn't able to find a wholesaler at the time, but I did find a few people selling similar products. Here is one that seems reasonably priced:

These use 1/4" quick connect lines, which you can get an adapter to garden hose size for a couple of dollars.

That looks promising. I wonder if its rechargeable and/or how many gallons it will do.

Thats ok, the one I have only does about .25 gal per minute. Its worth the 90 minute wait to fill up my 25g bin :)

I hope you find a new nitrate filter that you'll like just as much! :heart

It's a real bummer, my aqua world nitrate filter is under lock and key in a padded room lol. Don't know what I would do without it, takes my tapwater from 20-40 nitrate to 0. Fundamental problem with the product was is that is was too good. A cheap filter than can be charged over and over again simply by running salt water the other way, too good to be true.

Oh and in terms of other solutions, I also use a product call bionitratex. Its small packets of bio medio that encourage the growth of nitrate eating bacteria by providing them with a low oxygen enviroment and a source of food contained in the pouches. Mine ran out after 9 months, without the pouches working I was doing a 30% water change every 3 days just to keep nitrates under 20ppm, with all four packs I do one 30 percent change once a week and the nitrate level never gets above 5.

Oh, I forgot about the regeneration. Try this one in that case, which can be regenerated with salt:

They're pretty slow, looks like .5 gallons per minute.

In combination with something like this

I think I can rig it up to work as a nitrate filter in the tanks themselves.

It's worth a try.

In salt, we do it through a bio reactor filled with the polymer in a sump. I don't see why it wouldn't work in fresh. You need the pellets and a reactor (fancy name for a plastic cylinder) and a pump to tumble them with.

True.

Tell me if I am incorrect or too simplistic in my thinking. With the filter you showed, we can simply connect it to a pump that does 30gph (0.5gpm), and then simply have the return go back to the tank. Right?

Generally filters like these require household water pressure of 50 - 75 psi. It's not about the flow in this case, but the pressure. You would need something called a booster pump which takes water of certain pressure and boosts its psi. Booster pumps are considerably more expensive than sump pumps unfortunately and are designed for mostly clean water. They wouldn't handle chunks of anything flowing through them very well.

Gotcha! That's the part I was missing! :rofl

Thank you!

You are correct. With carbon based denitrification you want a very slow flow that just barely tumbles the media. Think fluidized bed. Requires low flow and very little pressure. This produces bacterial flock that generally can be caught with a bag filter.

I think a packed bed of ion exchange resin is the best way to go as the nitrates will never make it to the tank.
