Hi Jaden, nitrification is happening within 6 weeks typically, but for systems to hit full stride with nutrient availability, and a balanced overall ecology (not just nitrifying bacteria), it's usually at least 6 mo.s. These systems are like wine, they get better with age, typically due to diversifying ecology and nutrient accumulation. Regarding water changes- that's news to me. I've been running the same water for 8 years now. :)

Hey Rich, we run our system 24/7, but you don't have to! You can run it on a timed cycle if you want. Filling and draining every 6 minutes is not too fast, but you could slow it down if you want to save a little more money by using a timer (again, not required!).

We recommend that everyone monitor ammonia, nitrite, nitrate, pH and temperature daily in their systems (at least until the system is mature). Once it's mature it becomes very stable and predictable. These days we check these system variables only once or twice a week, if that (with the exception of temperature).

Hey Ryan. Thanks for your nice feedback! Yes, circulation is always a little limited with square tanks with rounded corners. However, the space efficiency with square tanks far outweigh the decreased circulation. It's a slight trade off, but one we would definitely make. Geothermal works well! We use it sparingly, but if there is an emergency, it's super nice to have on hand!

Hey Tom, there is a ratio to fish to biological surface area. There is basically a maximum number of plants that a certain amount of protein introduced to the system can support. Your fish ratios should be around 1# per 8-10 gallons. Your biofiltration (for most medias) should be around 1-to-1 tank volume to grow bed volume. The Number of plants you can fit into the grow bed will really depend on how much feed you feed to the fish. Thanks for the question - It can get a little complicated!

Hi, You can usually run the nitrates up to around 160 ppm before your fish start to notice. I would recommend shooting for a range between 20 and 80 ppm. Much higher and your aphids will get out of control. Nitrate is relatively non-toxic. Nitrite is deadly.

Hi Robert, The reality is much more complicated than that. The reality is that there are tons of different nitrifiers that operate optimally at different pH ranges, and bacterial biomass can offset reductions in efficiency. At the end of the day, each system has it's own nitrifier composition that is adapted to the variables in that system. The biggest thing is to keep the system stable. I'll do a Vertical food blog post on low pH nitrification soon.

The best way to lower pH is to increase nitrification and feeding rates. But, if your water is coming out at pH 8-8.2 and only working down to mid 7's over time, then you might look at installing an RO filter. They can be fairly inexpensive (typically costing a couple hundred dollars for a small to midsize system) and they're definitely a good investment on the front end rather than struggling and fighting pH over the long run.

It usually takes around a year to get the microbial communities established to the point where they're stable and efficient- once they reach this point and nitrification is stable (assuming there isn't carbonates built up in the system) your pH will start to drop in response to efficient nitrification, giving you complete control over what pH range you run your system at. Check out our stocking density video to see how many fish to stock/gal.

Hi Tad, Cycle your system first by adding ammonia and building up your microbial colonies, then add plants after 3-4 weeks and fish after 6, when your ammonia drops down to less than 0.5 ppm, your nitrites are less than 0.25 ppm and your nitrates are showing up consistently. Check out our video on cycling for more info!

To increase your nitrates, you're just going to have to feed more or increase your stocking density. If there is 0 nitrites and 0 ammonia, your system is cycled and you need to start planting [we assume you've already started since your nitrates are at 0]. It sounds like your system is in really good shape, you'll just have to up the feeding. Good luck!

While there are ideal conditions for lots of nitrifiers, they're also relatively adaptable, and there are hundreds, if not thousands of nitrifiers besides nitrobacter and nitrosomonas, so, you need to manage your water for your plants and let your microbes adapt to conditions. Separating the nitrifiers would require a huge level of control and not really do too much for your system- as would culturing them in tanks. Don't worry about them too much. They'll adapt to your needs.

Hi Ken, If you have a lot of aluminum in your system, and your run your pH really low (by aquaponic standards) then you should worry. By and large though, we don't have much if any aluminum in the system, and our pH doesn't usually drop beyond 6.0, which is still above the range where most Al toxicities occur (most Al toxicities occur below pH 5.0 or so. . .).

If your system is fully cycled, and you haven't done anything to wipe out your nitrifyers, then you basically need to feed more. Tomatoes are real nutrient hogs- they'll suck the nutrients right out of your system, so don't overfeed, but make sure you're feeding several times a day to satiation. If you still can't get nitrate up there, you'll have to add a couple more fish. Right now you're probably a little understocked to be growing tomatoes.

What's shakin' Bacon?? The biofilter should consume very little nitrate. The primary job of biofilters is to oxidize ammonia. So if you have an ammonia problem, that will help. However, a properly designed and properly stocked system shouldn't have those issue to begin with. In our system, of course, we use our ZipGrow Towers as a plant integrated biofilter and it works really well for us. The easiest solution is just to stop feeding your fish as much.

Do the 'best' of these nitrifiers operate at those conditions? Is there such thing as the best nitrifiers? My goal is to up the efficiency of filtering waste water if Nitrosomonas and Nitrospria had tanks dedicated to what they do 'best'.

This may invovlve growing the bacteria in vats first to ensure that all retail space is occupied by the the appropriate bacteria.

It's not entirely true with heavy plant growth and lower carbonate levels your nitrification does go down, but it doesn't really matter because the plants are sucking in the majority of the ammonium. This is only a concern at the beginning of the nitrogen cycle if you are doing a fishless and plantless cycle. It will still work, but a biological bed at 8.6pH and 300+ppm is going to work a lot better, as in being millions of time larger, than a bed at 6.8pH 80ppm. As well it isn't really about pH levels anyhow it is about the temporary hardness levels, (carbonate hardness) That is what determines the outcome and is what you should be monitoring. pH will swing throughout the day it doesn't mean your buffer is degrading.
