Sizing Aquaripure, Nitrate Testing, and Indications of a Problem
1. When sizing an aquaripure should you take into account existing sump and other filtration into the tank size?
2. Is there any reliable digital nitrate tests on the market recommended or just stick with API? I may be color blind as I can't tell the difference between lower counts.
3. These are the trouble shooting issues I have found on various forums, is there any other issues and remedial action to be taken?
a. Smell of Death
-Resolution: drain tank by flipping upside down. Dry it for several weeks, then reseed with new bacteria and start again.
b. No flow
-Check for clogs in pipe, use coat hanger to jam out gunk and clear line
-Check that pump is functioning.
c.Cloudy water (bacteria bloom)
-Possibly added too much vodka, change water or heavily aerate water to ensure fish have oxygen
I just hooked one up the other day. (dec 1) I now have a bacterial bloom going on. I think I saw/read somewhere that this is common and should pass in a few days. I have had blooms in the past (w/o the aquaripure) and they passed as well; I expect this to do likewise. According to the instructions, on an aquaripure just hooked up, do not feed nutrient until about day 4 or so. I think, mind you, think, that these units are seeded just before shipment so they should be ok.
It smelled to high heaven when it first flowed, but it faded away. \
There are instructions to mothball the unit in instructions if it ever becomes necessary.
I am still in experimental stage.
bloom has passed and water has cleared.
when I first started the aquaripure up, I was beset with hydrogen sulfide (phate?), or your classic rotten eggs. was pretty strong for a few minutes, but it passed.
I increased the air flow to the foam block filter.. think this is good to offset the oxygen deprived effluent from the aquaripure, once it really gets cycled.
also, use the liquid test kits: I have an API one. The liquids are much better, give better results.
5 ppm on nitrates? that is actually a fairly low reading,.
you using strips? liquid? Or is your scale different from mine? I use the API liquid nitrate tests and it comes out as 10 ppm. (I do weekly water changes of @ 1/4 - 1/3).
The 20 gallon with the aquaripure is an experiment on my part. It is further away from my dumping window (yes folk, the water change goes out the window..) and if I do not have to change the water as much, this will suit me just fine.
Will give the results of the test @ the 1 week mark.
5PPM nitrite is not low
The effluent of the Aquaripure often measures nitrites in the effluent while it is cycling. There is actually a specific reason why this occurs.
There are actually multiple species of anerobic bacteria. One reduces nitrates to nitrites and then a separate species of bacteria reduces nitrite to nitrogen gas. It is like the reverse of the original aerobic nitrate cycle. Do you remember how first there is a spike in ammonia and then there is a nitrite spike and then the nitrates develop? It's because it is handled by different species of bacteria.
In the case the the Aquaripure there is normally no danger to the tank as it cycles because your tank has bacteria in it that will convert nitrites back to nitrates much more quickly than the slow flowing Aquaripure will produce nitrites. Something must have happened in this case to inhibit the denitrifying bacteria in the tank?
Soon there will be enough anaerobic bacteria that reduces nitrite to nitrogen gas to begin reducing the nitrates 100% and then you will get the results you expect.
2) I have seen them but I have never used them. I do sell the digital pH and ORP meters but I personally do not use digital meters.
3) You do not want the flow through the filter to be completely cut off for more than 4 days. This will cause the bacteria inside to start to die and for toxins to start to build up. After about 2 weeks is when that death smell will kick in. The bacteria in it have literally died.
If there has been no flow through the filter for 4-11 days then I recommend letting several gallons of effluent drip into a bucket to be discarded. Then you let it drip back into the tank. Wait a few more days after this before injecting nutrient again.
If there has been no flow through the filter for more than 11 days or so then I recommend emptying and drying out the filter before using it again. That will then make it completely safe for reuse.
guess I need new eyes.. glasses don't help much anymore
