ATM Ask The Shark “Nitrifying Bacteria” by ATM Shark | Mar 2, 2013 | Front | 26 comments Share this:FacebookTwitterGoogleEmail Related 26 Comments jerry coble on February 4, 2013 at 8:42 pm I am looking to see what bacteria is in your Colony product. I live in Hawaii and work at Petco. Microorganisms are highly regulated here and the list of what is acceptable to import is small. Is the scientific name of the beneficial bacteria listed somewhere? Reply ATM Shark on February 4, 2013 at 10:07 pm Hello Jerry, Yes the names of the bacteria are listed on the bottles. You can read more in-depth and watch our tutorial video on Colony here http://acrylictankmanufacturing.com/products/water-treatment/biologicals/colony/ Thanks! Reply firstname.lastname@example.org on March 6, 2013 at 5:43 pm Yes cycling a 40 gallon breeder. Used Colony to start two weekend ago. Two weeks later Ammonia 1.0 ppm, ph 8.2, nitrites 0, nitrates 5 ppm. Seems slow. Can I shoot another 8 oz in the. Tank? I have two juvenile Malawi peacocks in the tank. Reply ATM Shark on March 6, 2013 at 11:50 pm Hello kent, Freshwater nitrifying bacteria function at their optimum conversion between 7.2-8.0. So at 8.2 they have been inhibited a bit. That explains why with Colony you’re getting full conversion to nitrate but its a little sluggish. Another 8oz of Colony will pick up the slack for the inhibited batch currently in there and if you drop the pH to around 7.9-8.0 you’ll be really rockin’. Keep us posted. kent on March 10, 2013 at 4:33 pm 72 hours after another 16 oz ( doubled it because of the ph difficulty to lower just .2) colony we got 1.0 pp ammonia, 0.0 nitrite 5- 10 nitrate. We had a nitrite spike yesterday . 5 ppm. We want to add our full fish load in sooner than later but do not want to put the fish at risk. Any suggestions. Also, our base tap water test shows 1 ppm ammonia so could something be giving me false readings? We did condition the water before we put in. we have done any water changes. We are still using API master test kit. Ps. My 10 year asked me to write y’all since Brett says we can cycle the tank instantly. ATM Shark on March 10, 2013 at 4:49 pm Hey Kent, It looks like you’re pretty much cycled. When you’re getting the kind of nitrate readings you’re getting you have already the conversion that hobbyists have waited weeks and weeks for, historically. It is possible you could be getting readings of ammonia off the chloramine in the tap water. Typically tap water doesn’t come out with that much ammonia, or if any, because there are strict regulations on ammonia levels in municipal water. Many hobbyists will have spikes they can never get rid of, yet the fish always remain healthy pointing to a false positive of some sort. How do the fish look? Are they swimming around and happy? Are they eating right? Stop feeding for three days and do no water changes and at the end lets look at two things: 1.) If nitrate has risen, and 2.) If so see if the ammonia went down relatively. Keep us posted! It looks like you have done this very well. kent on March 10, 2013 at 5:00 pm Fish look great. We fed them by hand ( yes they eat out of hand pretty cool.) we will get two More and see how they do. If it works out we will fully stock next weekend. Since we were so conservative at the beginning, should we hit anther 8 onzes when we fully load? We are just trying to get the fish in the tank fast to control aggression. I promise I will not bother you again. ATM Shark on March 10, 2013 at 5:20 pm Hey kent no worries that’s what we’re here for! Let me kind of shed some light on what you’ve got with Colony. Each bottle is fit for a full, appropriately stocked system. I know it seems scary and backwards, but to keep the full population that Colony provides there needs to be an adequate amount of food and fish to provide it. Let me explain this dynamic. You have about two weeks to keep that full population that Colony offers. What I mean by that is that un-fed nitrifying bacteria will start dying at that point, so if you have only two fish you will only have a size colony of bacteria for two fish. I would like to see a few more fish go in immediately so we’re feeding all that bacteria so it doesn’t die back to a smaller, two-fish colony. After a couple of days add more. Keep your feeding extremely light over this time. This will keep low spikes while still feeding the bacteria. Like I said, its okay to go slower if you like but don’t go too slow with Colony or you shrink the bio-filter and it kind of defeats the purpose. Let me know if you have any questions on this. Colin on November 7, 2013 at 6:20 am Hi, was wondering if you could help?? Recently set up my first saltwater aquarium. It’s a 65 gallon fish only tank, which I filled and began to cycle with fish (on the advice I my local fish store) 2 weeks on fish are fine and feeding well and seem healthy enough but cycle is still not complete. So I purchased some of your colony product and it should arrive tomorrow. I was just wondering if its still safe to use this two weeks in to the cycle, and if so how should I go about it, I.e water change first or not? An does this product get added directly to the tank or the filter area? Thanks for any advice Reply ATM Shark on November 7, 2013 at 4:18 pm Hello Colin, Thanks for the question. Yes, Colony will jump start your cycle whether you start it from scratch or weeks in. I would recommend doing a water change prior to adding Colony if you have any dangerous levels or ammonia and nitrite. Colony is going to work pretty fast, so I would recommend stop feeding for now. Make sure you shake the bottle well, turn off UV and protein skimmer and no water changes for 4 days. Slowly resume feeding to normal levels again when you see nitrate and nitrite levels have gone to at or near zero. That’s how you cycle quickly and keep the fish safe. Please refer to our field guide if you have any other questions. https://docs.google.com/document/d/1Fza4_ZtPFt20OzsZH5GdKwIKKQc8kBUPq9haEph0s_0/edit Keep me posted on this please! Gary on October 28, 2015 at 2:55 pm When first using colony should I have my skimmer on?.. What is the process involved?.. Should I wait a certain amount of time before I turn my skimmer on? Reply ATM Shark on October 29, 2015 at 9:29 am Hey Gary, Thanks for getting in touch. You will need to shut the protein skimmer off for four days while Colony attaches to filtration media. After this point it will be out of the water column and the skimmer can go back on. Neil on November 30, 2015 at 1:06 pm Hi put colony in a new salt water tank filled with pre mixed salt water added 4 fish today after adding colony and have got readings of Ph 8 Ammonia 0.25 Nitrite 0 Nitrates 5.0 Big concerned about the ammonia and nitrates please can you advise Reply ATM Shark on November 30, 2015 at 1:54 pm Hello Neil, Thanks for getting in touch with us. It looks like Colony is doing what it is supposed to do. Can you tell me what day you introduced Colony and what day you introduced the fish? Thanks! Stacey Josh on June 25, 2016 at 11:48 am Hi i need some help i have salt water tank 55gal and i used your colony along with a pair of clown fishes ive been water testing every single day and all the readings i had was 0.25 ammonia 0 nitrite 0 nitrate , and im on my 3rd day now, ive applied colony on a wednesday night along with the fishes and its already saturday any help and advises? Shall i buy a small bottle of colony to help it out? And ive been topping off the water too with RO water to correct salinity, help please? Reply ATM Shark on June 25, 2016 at 12:20 pm Hey Josh, Thanks for reaching out. Please reach me at stacey @ acrylictankmanufacturing . com (take out the spaces). Rebecca on July 13, 2016 at 12:34 pm I’ve bin putting trust the shark in my tank I’ve bin going for my water tested regular it is still really high on ammonia nitrite and nitrate does anyone no how long it takes to clear the tank I’ve started doing a water change every week Reply ATM Shark on July 13, 2016 at 12:41 pm Hello Rebecca, Can you tell me a bit about your tank? I it freshwater, saltwater, how long has it been up? Thanks! Darren Pattinson on August 6, 2016 at 10:20 am Hi I added some of your marine colony to my tank last Sunday afternoon and added a few fish I fed on first day then haven’t fed since it’s now Saturday been a week since adding colony and my readings are ammonia 0 nitrite is still at 2 and nitrate is 50 . Skimmer is still switched off and I haven’t done a water change . Is there any reason why my nitrite hasn’t gone down yet Reply ATM Shark on August 6, 2016 at 1:15 pm Hey thanks for reaching out. Do you have live rock in this tank? Darren Pattinson on August 7, 2016 at 9:57 am No I use dry macro rock and dry crushed coral sand ATM Shark on August 7, 2016 at 1:18 pm Okay, I see. 50 nitrate after just six days is a ton of conversion. I’m suspicious that the nitrite reading is a bit exaggerated due to nitrogen interference. Based on the enormous amount of nitrite that has already been converted, the rate vs. reading doesn’t add up. It isn’t unusual for this to happen with consumer grade test kits. If this isn’t the case then the most likely cause would be fluctuating or dropping pH recently. What has the pH been? Mark on August 16, 2016 at 2:22 am Hi our tanks has been running for around 12 weeks and was cycled old school with a prawn everything went fine and cycled OK then we made our first mistake put to much in in a short time wich in turn kicked off another cycle so we added your marine colony with after 2 days brought ammonia nitrite back down 0 we turned off the skimmer etc and just run with the return pump it’s been 6 days now I have just turned on the skimmer and fitted the filter sock when is it best to do a water change because it’s not had one now for 12 days Reply ATM Shark on August 16, 2016 at 8:27 am Hello Mark, you are clear to do a water change whenever you like. The only it is recommended to not perform a water change is within the first 4 days of dosing Colony as it might still be free floating in the water column. I hope that helps and let me know if you have any other questions. Jamie on October 23, 2016 at 11:40 am Hi I have a 50gall tank with dry rock and dry sand I have 2 189l bottles of marine colony have many fish am I going to need to get a good cycle Reply ATM Shark on October 24, 2016 at 10:58 am Yes, indeed.
