Questions about Biopellet reactors

I watched a few videos on YouTube about the subject and I am getting more interested in this new concept.

It seems like these little pellets are made from the sludge on the top of beer vats... lots of sugars and compounds mixed with different plastic polymers. The concept is definitely interesting... the bacteria colonize the pellets and start breaking down nitrate and phosphate naturally, by being provided a specialized growth medium. Kind of like how fluidized bed filters use sand to reduce the amount of ammonia and nitrite in the system.

It is making more and more sense why a lot of the time people are not having good results with these reactors... it's because many people don't fully understand the biology behind it. People say to not put one on an established system - but these people didn't know exactly how it worked, and bought the cheapest units available to start testing these biopellet reactors.

Fluidization of the pellets is important to keep it oxygenated, but more important is the outflow of the water coming from the unit. The cheaper systems that people have running don't have any regulation on the outflow of the water - and therefore reduce their nitrate and phosphate too rapidly in established systems.

Another thing that I have run across is that these biopellets produce a lot of biofilm. This biofilm can be good for some corals to eat, but too much of it can cause algae problems - so there is a balance. Some people have gotten away with this, however, by putting the outflow of the biopellet reactor to a T onto the protein skimmers inlet. The protein skimmer then becomes highly activated and removed the biofilm from the system but leaves enough in the water to be beneficial.


Ok, so that's the extent of my research on the subject.

1. Is there anyone on the forums currently running a biopellet reactor, and what has been your experience with it?
2. Is it essential that a good protein skimmer be employed in the system for tank health
3. Is it worth the money to invest in a system like this, or is it just another "fad" that the aquatic industry has come up with?
4. Has anyone seen any tanks with long term success?
5. Does anyone know if a system like this has been used on tanks with SPS corals?



I'm getting the courage to pay for my RO/DI unit to be fixed and maintained properly and if that is the case, I might set my 75g tank back up. I just was gathering some information.

So, anyone?

A system that has a biopellet reactor and a skimmer and other basic equipment can be just as successful as one with a fuge, algae scrubber and water changes, right?

Just looking for a different direction, I guess, not just a fad.

I did a lot of research on BP's a couple of months ago. I think most folks running them are trying to maintain nice SPS systems. They are looking to get nutrients out of the system fast/well. They use BP's to get close to an ULNS. I have seen some folks use BP's on mixed reefs, but mostly SPS systems.

The recirc reactors seem to be the preferred setups. And having a great skimmer is a must with BP's. The research I did says to put the reactors output hose either directly into the skimmer intake or as close as you can direct it.

I have read that lots of folks will eventually get a cyano outbreak with the BP's... Not sure why, but lot of folks said it will happen. Aggressive vacuuming and additional flow help. That was the big issue with some folks, but it seemed manageable to most.

I will follow this thread, as I am also considering adding a BP reactor to my system and taking my fuge offline.

This BP reactor is different then the Aquaripure, sound like the same concept. Flower has been running this unit for years.

Mr. Limpid,

The aquapure filter is completely different from a biopellet reactor. Aquapure filters use vodka where these do not. It is though a form of carbon dosing because the biopellets are made out of a mixture of polymers and carbohydrates.

SV,

Thanks for your input. I have yet to find people remarking that BP made their tank have some cyano. I'm thinking that they put the reactor online and immediately started overfeeding and that created a problem that was taken care of over time. There is a system at the museum of natural history on my college campus and it is running biopellets and a large skimmer only. I have the privilege of knowing the professor that takes care of it and the honor of feeding the tank one time. He feeds A LOT in his tank and doesn't have issues with nitrates or phosphates until recently when his reactor got something plugged up in it.

I'm seriously considering one of these units after I set my 75g tank back up. I'm going to have to do some more research, of course, to see what exactly I need, but it will be fun to see how this new little system of doing things works. On paper, I think I believe in it. In practice, it might be a different story.

I'm half way through saving up to permanently fixing my RO/DI Unit and then going to save up some for a few filter changes. I swear, I am going to have an awesome tank!!!!!! AHHHH!!!!

I agree the recirc bio pellet reactors are a better choice.....better flow control. Seth a good place to check out is whoever euro reef became, but they make some of the best reactors out there, and they actually have a pretty detailed video on the subject and how they function.......

You're talking about Reef Dynamics... and yes, I have seen all of their videos on the subject. :D

If I was going to get a BP reactor (and I still might!!) it would be the reef dynamics one. I like the recirc design and the ease of flow control. I like their videos as well. They are a bit spendy, but it seems like a quality product.

I am encourgaged that you did not find many folks say that they did not have cyano issues. I would make sense that they start feeding heaver and that would lead to the cyano issues.

I personally like the way the Reef Dynamics is made... Other BP reactors don't have the same design and control as the RD one has.

RD has it to where you can keep the exact same tumble rate, but have more or less coming out of the reactor to control the speed at which the nitrate and phosphate decreases. That's a very smart design that other reactors are lacking.
