The pellets don't actually need to be changed out, they get consumed by the bacteria as they run so they just need to be topped off as they get consumed. It will vary but 4-6 months would be pretty typical.
The pellets don't get changed out you just top them off as they get consumed. Typically this is every few months (3-6).
My tank is currently lightly stocked, with 330 gal of total system volume
250mL per 50g would be a pretty typical load. In your tank that would be about 1750mL, which is about 7 cups.
I have included a link to the instructions for Bio-pellets below. We do recommend the half dosage to start with to not shock the system. Feel free to let us know if you have any further questions!
Biopellets need to tumble to be effective, and in a canister filter the bacterial film that they can produce may quickly clog the canister making it become constant maintenance. Biopellets are best used in a standalone reactor due to the flow requirements and the specialized screens that are normally used. We really like the Reef Octopus BR series as well as their Space Saver series.
We certainly recommend Carbon and GFO to help with phosphate removal and clarity. For bio-pellets we do not recommend them in the standard BRS reactor as they will clog. Ideally a dedicated bio-pellet reactor will need to be used. Feel free to let us know if you have any further questions!
They are basically food and surface area for bacteria so you actually don't ever remove and replace them. You just add more as they get consumed. Once up and running thats usually once every couple of months.
We recommend 1 cup (236 ml) of BRS biopellets per 50 gallons of system volume. See Instructions.
Maintaining low nitrates is key to maintaining the best coral coloration, healthy fish and avoiding algae outbreaks. Fish foods and resulting waste eventually break down into nitrates. Aquarists’ primary method of dealing with nitrate removal is water changes but over the years we have developed a few ways to remove nitrates with equipment like refugiums, sulfur reactors and deep sandbeds. All of these methods work to various degrees but are often less efficient than we would like or the level of complexity, expense and maintenance is beyond what the average reefer would desire
Solid carbon dosing (biopellets) has recently become an extremely popular method of removing nitrates from the aquarium. The exact method of denitration can be different for each tank but it mainly consists of a few things:
- Nitrate laden Bacteria is removed via the protein skimmer
- Bacteria directly converts nitrite into nitrous oxide so nitrate is never produced
- Bacteria consumes nitrates and processes them down into nitrogen gas
- Nitrate laden Bacteria is consumed by tank inhabitants like corals and sponges
Depending on the system it should take 4-8 weeks for the bacteria population to multiply and begin its work on your nitrates. Once you have the reactor going we suggest not making any adjustments for 8 weeks. Give the media and bacteria time to adjust to the parameters found in your tank and begin working. The absolute best advice we can give with this system is to set it up and forget about it for two months. Unless something is obviously not right resist all temptation to make any changes until the two months are up.
Great Pellet By Golden Pond on 1/14/2017Golden Pond would recommend this product to a friendThese are just as or better than other Brands. I've found use a 1/4 as much as prescribed. They work better and faster this way. Dissolves very slow. I've had mine in 8 months and not much has dissolved but kicks nitrates and Phosphates butt 24/7. I don't even run GFO anymore after a month with this on my system. No need.
Best pellets By brianOH on 4/8/2016brianOH would recommend this product to a friendPellets where smaller than i'm used to but aside from that they tumble great as long as you soak them for 48 hours. stripped my water clean in no time.
So far So Good By RudyEnt on 3/30/2016RudyEnt would recommend this product to a friendI started to use bio-pellets about a month ago. So far so good. I decided to start with much less than suggested and test my water parameters. It is a good thing I did that. I am using about half of what is recommended for my size tank and my numbers are doing great. So I am not going any higher. My skimmer has been putting out a very dark gump. I assume that it is working as everywhere I read from, that is what it is supposed to look like. I am using the pellets with the BRS reactor so I was able to adjust the flow to where they tumble nicely.
AWESOME! By carmelgu on 12/30/2015carmelgu would recommend this product to a friendHave the Reef Octopus BioChurn 120INT on a 120 gal reef tank using BRS biopellets and the ZeoBac, ZeoSnow, Zeo 7 system....within one week my water is SOOO clear and coral is SOOO happy! Awesome product!
Great product By Sgt Harold on 12/26/2015Sgt Harold would recommend this product to a friendBeen using these since the I started my bio pellets reactor ! They don't grind down fast! A nice and very much will be reordering !
Very Nice! By Robert on 10/2/2015Robert would recommend this product to a friendThis product is so easy to use and works great, just make sure you give it time to work.
Would only use on Fish Only tanks By Jonathan on 8/28/2015Jonathan would recommend this product to a friendThese pellets work fairly well in reactors but only with lots of maintenance. A larger than normal % of them will float and clog your reactor.
Bulk Biopellets By chcuk on 8/15/2015chcuk would recommend this product to a friendThe BioPellets worked great. My son and I have used these several times.
BE CAREFUL!! By James on 4/17/2015James would recommend this product to a friendDosed the recommended amount: 1 cup per 50 gallons. I dosed 2 cups for my 100gal tank. Day 5 I came home from work in the morning and saw my tank was extremely cloudy (normally crystal clear water column). I noticed a bad odor coming from the sump area. I discovered my Green Bird Wrasse had jumped from the tank, and a few hours later my Rusty Angel was dead on it's side.
Bio Pellets will cause I major drop in available O2 levels in your tank. BE VERY CAREFUL with these pellets. DO NOT start off with the recommended dosage. I would start with 1/4th of the dose. Also, make sure you have a VERY GOOD skimmer to remove the increased skimmate from these pellets. I have stopped running my reactor and hope that when I get home in the morning I don't have anymore dead fish.
Not sure By Brandon on 4/9/2015Brandon wouldn't recommend this product to a friendI've used TLF pellets with good results. These BRS pellets are larger and seem to be less dense. I'm having a floating issue with a small % of them. The rest of them won't settle down to my satisfaction. The tend to hover in the middle of my reactor. Time will tell!
good product By subie on 2/22/2015subie would recommend this product to a friendWorks good for nitrate so far..
Good so far By David L on 12/22/2014David L would recommend this product to a friendI was sent the BRS brand of bio pellets after having issues with TLF brand floating and clumping. I had no issues with the BRS brand from day one. Now lets see if the bio pellets help reduce my nitrates.
