Anaerobic Bacteria

As of this morning it looked to hit the red zone (40 or 80)



Tested the water shortly after the water change. Getting 0 is odd i usually hit 5ppm, im thinking that if indeed this thing is working the remaining water in the sump was filtered while i went through with the wc. I drain the sump half way and go finlevel on the display so there wasnt allot to filter.Today i didnt use the pump to drain the tank so it probably took over 2.5 hrs to drain and fill.



Just tested when i got home tonight and it looks to be about 5 or 10ppm

J J. H. I don't think hydrogen gas would be a problem in a well ventilated space

The long strand turf has grown in very well on the Texas holey rock. It gets mowed about twice a month. This tank has a 8" x 16" single sided water fall algea scrubber.
The nitrates are around 15ppm. With a 45 % WC once per week. It never gets vacuumed, relies on a full length return water bar, a 2" air lift , and bi weekly filter floss change.
My wife over feed the fish. Flow is 500 gph in 75 gallon display.
I wash and reuse my filter floss, and collect the brown water waste. Which gets pumped to the garden.
Been busy on other projects, as winter arrives. I will be more involved in to aquariums, mostly aquaculture.

This is my top tank. Nitrates are at 35 ppm. The 660nm scrubber lights are still working so, it will be getting upgraded. The leafy green is native violet. The other stuff is full amphibious native moss, and long strand turf algea.

Feels like the band is getting back together.
Nice update mark. At.this point would you say the water fall scrubbers are more reliable than uplfow ?

The upflow is covered with turf algea, simply to pull and low maintenance. I got an easy inexpensive light solution.

The waterfall, grows mostly soft algea. It would be great if I could get some turf algea growing.

The first posting has less nitrates, only because it has the refugium effect, of all the turf algea growing. It grows very rapidly in the high flow, well aerated return water, of a wet/dry trickle filter sump.

It gets hand pulled weekly. The down flow from the return . Keeps it laying flat.

Main concerns for sulfur systems that he mentioned is that when flow rate is too high and it isn't fully cycled it can leach sulfur and there is nothing to consume it which can be harmful to fish. Also without good discharge or aeration hydrogen can also poison your fish which is a big concern.

no worries about hydrogen in the air? I'm thinking of the Hindenburg, hydrogen is not your friend.

The type of hydrogen the person at Hendre 's lfs was talking about was probably hydrogen sulfide. It has a strong rotten egg smell and can't be missed. It can be produced in denitrifiers, deep sand beds, or wherever there are conditions void of oxygen and nitrate. This is why I try to never let the output of my denitrator fall all the way to 0 ppm nitrate.

This harmful ? kno4te notice any odor ?

I remember the lights gicing you some trouble what was the fix ? I still plan on re-tackling this method at some point

Can be. Apparently good aeration post-reactor gasses it out
