I ran them in my old tank for a few months and did notice a drop in nitrates. But then oneday we lost power and when it came back the return pump wouldn't restart. I had to service the pump so the pellets (since they were plumbed off a manifold on the return) didn't work for a few days. In the days that I awaited a replacement return pump I noticed the pellets mutated into something else. It looked like coleslaw inside the reactor. It worried me to think that you can so easily potentially nuke your tank if something were to go wrong. I think what works best is a recirculating reactor which is what I needed and with it's own pump plugged into a ups. I didn't want to spend more money on it replacing the reactor so I decided to d/c it. It's really 50/50 on the response you'll get with using them.
Get a recirculating reactor, you can fine tune it better.
Marvin is correct. That's the next move for me if the two algae scrubbers I'm planning to run doesn't cut it. More money I'll be shelling out but it's ok, it's to sustain life in my reef tank. LOL
A biodenitrator would be better option .....
Maybe, but like you I have bags of the NPX pellets. LOL
I have to wait and see if I even have space for it. Currently the algae scrubbers are top on my list to get nitrates and phosphates down.
The algae scrubbers and biopellets won't even compare take a look at the data in the build thread Dave and I put up ......that's a 120gal a day water change its capable of on my system.......imagine the size of your system ....no3 and capable of po4
Matt,
Without being able to compare apples to apples, you can't really say one is better than another.
It would be nice if someone could conduct a study comparing the different methods. However, like many things in our hobby, there is little scientific backing or testing as how they function in the aquarium.
I believe each system has its pros and cons. I've seen successful tanks using all different methods.
