If I have a fish or turtle tank I'm feeding them food and their excreta is filling the water with nitrogen heavy nutrients. Those bacteria in the filter media are consuming the nutrients that would otherwise feed the algae that turn my water into green pea soup. In a reservoir would these same bacteria remove nutrients intended for the plants? What am I missing here?
The bacteria don't remove the nutrients, they convert (oxidize) them. It's funny, but the same genera are at work as in the water, Nitrobacter
, and they are referred to as the nitrifiers. There is now good science showing Archaea
are also at work oxidizing. The sequence goes like this: NH4 (sometimes NH3+/-, I think
) ---> NO2 (still toxic form) ---> NO3. It is important to remember, however, that high nitrates are not necessarily a good goal with plants, but nitrogen conversion and utilization is.
Also, another 'of note' for me is that it is typically high phosphorous or phosphate levels that tend to lead to algal blooms.
In all these cases, the nutrient in question does not disappear, it becomes 'fixed' into the bodies of the plants or animals in question. When they die or shit, then it is no longer fixed.

Even if it's chilled, there are microbes that can live. What you're missing is that the biological filtration media is providing TONS more space and homes for the microbes. The surface agitation is necessary whether or not you're culturing the microbes.
Has this helped at all? Hoping so.

I'm now entering the 6th week of flowering. Deep, dark color...super bud development. Strength of plants is obvious, EC is stable and easy to manage. Other than the overall health, I have noticed nothing else...certainly nothing negative as a result of using these filters. I now have them in all 3 of my res, plus my EZ cloner...never seen better results in there either, nubs in 2 days! bursting roots in 4!!!. And that was in water I was not getting results in...just put the filter in rather than changing it out (lazy) didn't really "need" the cuts just put em in...blowing up. It's crazy!!
I will try to see about eliminating the carbon...trying some other items ie: bio balls, lava rocks, etc. But honestly I don't notice anything negative about just using the filter as it came in the box.
SeaMaiden I searched those canister filters and Eihem products in particular. Look interesting, but what what what...$129 or more...um no! These are $20 for the 10-30 gal version $11 for the 2-10 gal version (which I put in my cloner) They even have a 1-5 gal version which I'm planning on putting in a 5 gal stand alone DWC bubbler bucket.
I think I'm in love....give em a try!! Cheap, easy, readily available...go go go.
Good Luck All
Sorry, I totally fish-geeked out on you. Yes, the Eheim products are expensive, but they last a lifetime, quite literally. I so wish I hadn't gotten rid of all my aquariums and gear right at this moment. Storage headaches aside, of course. A big canister filter could be hooked up in-line with all your reservoirs and cloner, but I don't think that would be very configurable for you.
There are, I think, cheaper versions of what you're using, too. Most fish shops use them, they're called Supreme Super King aquarium filters, and the turnover these things produce is just fucking ridiculous. I've seen them mostly used for feeder tanks, which are typically very overstocked/crowded and so often have disease problems. These things, oh my God the flow through these things is just unreal!
Whoa.... I just had a moment remembering the sound of a large fishroom, no one else in it, nothing but the sound of water falling and splashing. Nothing but thousands and thousands of fish... That was pretty wild.
I love fishrooms. Truly, I do.
