NpX-Bio Beads! New O.C. Product launch!

[Bzar]

@DiverDude: I've run mine both up and down stream from the skimmer, and no real difference for me. I did find an increase in polyp extention with the reactor outlet downstream from the skimmer inlet...pehaps the corals like using some of the mulm (nutrient rich bacteria) for food.

There are others on various forums that don't run the reactor outlet upstream from the skimmer....no deadly results that I've read.

The reason for that suggestion towards putting the reactor outlet near the skimmer inlet (or upstream) is so the skimmer has a greater chance to skim any of the nutrient rich bacteria out asap, and to ensure re-oxygenation (is that even a word? it's late of the water in a probiotic system....again doesn't seem to really matter IME and from what I read. Perhaps if you have a very inefficient skimmer and/or very low through sump GPH...in that case a probiotic system of any kind could cause some harm to the system in terms of bacteria build up, ph problems, and low O2 levels. If you compare it to some of the liquid carbon dosing systems (like vodka carbon dosing) the reality is that there's no way to contain that systems nutrient rich bacteria into an "upsteam" situation...what's important is your GPH through the sump/skimmer area, because it's processing of the water column through the cleaning system (skimmer) that counts. General rule is about 10x an hour through the sump, and a skimmer that`s got good reviews....and imo rated 2x more than your tank :P

If you try with the reactor outlet downstream from the skimmer, and are worried about how it'll work out, then just keep an eye out for bacteria strings (white hair looking strings floating from the rocks, glass, substrate, powerheads, etc.) low PH, and/or fish heavy breathing. If you notice that stuff happening you may want to try with the reactor outlet "upstream" from the skimmer or think about getting a new skimmer or more GPH through the sump.

There can also be initial challenges with biopellets in systems that have heavy amounts of unchecked nutrients....if your tank is some what mature and may have high amounts of nutrients, then it's adviced to add the pellets slowly. That way you wont shock the system with a fast and furious outbreak of nutrient eating/rich bacteria. Say you need 1000ml...best to add 100 to 200ml each week to let the system develop safely.

It's late, I'm tired, hope that makes sense and helps .... is it wrong that I love nutrient exporting so much?

Bzar: Thanks for all the info. Makes a lot of sense. I'll have very nearly 10x the system volume going through the sump each hour and it's a new skimmer that while not hugely over-rated for my system, is certainly adequate. I haven't run it yet (sump isn't quite done) so I'll have to reserve further comment on it until I've had a chance to run it for a week or 2.

I'm planning on running ~250ml of pellets in the system but was going to start with more like 100 ml to start and then add a little each week for a few weeks since the tank is not mature and I'm having issues right now with Ich, medication, and some minor algae blooms that come from running with no skimmer (due to the meds). Once things settle, I'll bring the pellets online and see how it goes.

I could not have explained this better myself, one of the reasons to aim the effluent into the skimmer is for re-oxygenation and nutrient export. This is not as big of a deal once the Beads have been running for a few weeks; however, upon initial implementation of the beads bacterial clouding events can occur when there is high nutrient levels in the tank. Clouding events happen when there is a major bacterial bloom that over spills from the Bead reactor and clouds the tank, the cloud of bacteria alive and dead can cause issues with PH and low dissolved oxygen.

Once the Beads have been running for a few weeks you can easily run them downstream from the skimmer, the excess bacteria are taken up by all of the Corals and fauna in the tank....

Hope this also helps!!

i have the pellets for few months now and everything was running great. My only question is can i rinse the pellets? Because i am using Phosban reactor and it has turned a little bit dirty now, since i stop using filter socks..

thanks,
