I'll look at the Cadlights as well.

This one would work for my system... anyone know if I can remove the pump and feed it with the manifold from my return pump?
The pump on the those are supposed to be for the flow in the chamber. If I remember correctly, the last time I talked with them about these is that no feed pump is required. It pulls the water from the sump into the reactor. It's an all in one with no extra pumps needed.

I have this reactor. No feed pump needed. The pump included is to recirculate the pellets and draws in a small amount of tank water. Upgraded from the cadlights reactor. The reef dynamics is a lot easier to add pellets, maintain/clean, and adjust.

Now Broc is saying he wants to keep it. Lmk if/when you are interested and I'll find out more. ..

I don't think that there is a proven benefit of a recirculating reactor. It's nice to have the extra control but how do you know what to control and the affects of the control. If you want to increase your effluent, what does that do? If you want to increase the tumble, what does that do?
What he said!

Bacteria is too simple of an organism for such a complex solution. I guess the only benefit is that you could theoretically prevent the bacteria from consuming all nitrate and phosphate. I prefer to relax and let the little bacs eat!

From my understanding that's the main reason. Slow down output, and bacteria won't consume nitrates/phosphates as fast.

When doing research before I started BPs, I would say 90% of people's complaints were that over time pellets would end up clumping. I've been running BPs for almost a year and have not had one issue with clumping. It seems to me the recirculating reactors tend to be a bit more consistent with the tumbling.

biopellets IME are the most complicated, equipment heavy way to does carbon. IMO the recirculating feature lets you partially take it offline without physically removing it from the system & restarting the culture. vodka & vinegar for me.

recirculating is the only way to go really. I dont use biopellets because they were too difficult to manage. It either stripped the nitrates and not the phosphates, or it stripped both too fast and made the coral look horrible. It was really difficult for me to find the right amount to use on my tank, and I honestly didnt really need it, I was just trying it out. The reason I say recirculating is the only way to go is because you actually have control! see, the classic biopellet reactors (the one I used) had a constant and very fast flow that kept the biopellets moving. This also cause my water to come into contact with the biopellets at a really fast rate. Once you have an established bacterial population, it becomes very effective at stripping the nutrients out of the system. The really fast water rate and the extremelly efficient bacterial population causes your nutrients to be depleted waaay too fast. The recirculating reactor provides high flow within the reactor, which is needed for the bacteria colonies to grow and thrive, while also allowing you to control the rate of water comming in and out of the reactor. This allows you to control the rate at which your water comes in contact with the bacteria within the reactor. If I had the money, id give it another try using the recirculating reactor. I'll probably incorporate it in a different system because I have mostly lps and they need a slightly more nutrient rich environment. That's just my two cents though

I have 4 aquamax reactors running on 4 different systems. We have about 4 more customers who's tanks we maintain that are also using this reactor for biopellets. Not one of them have a problem with clumping. All spin perfectly. Replacement takes literally 5 minutes. Max.
I also don't "soak" my pellets for a day either. It's not necessary. Add new pellets and watch for an hour to make sure they mix well and your done. That's it.

This is likely a dumb question... Can't you just use Y fittings and tubing to make a non-recirculating reactor a recirculating reactor? It just seems all they're doing is redirecting water back through the reactor. I would think a Y fitting on both the incoming and outgoing with some ball valves and you're done.

Yes sir i moded a tlf 150 as a bio pellet reactor and it works pretty good one is a mod inside the reactor so it has good tumble and the other is the recirc mod

Heres the tumble mod i did

this was my little diagram i drew up before building it ill see if theres anythin on youtube building one so its not too confusing
Heres another less complicated little drawing




Sorry for the rookie drawings hope it helps lol
