View Full Version : Different Constraints From Previous CO2 Threads

Folks:

I have postponed generating this thread hoping that my question would be addressed in the many CO2 threads on the Forum but no joy.

My main aquarium is one of the primary aesthetics of my den and an external CO2 tank and/or regulators will not work.


From another CO2 thread:
What's your filtration setup? What lighting do you have ... ?

110G, 30" deep bowfront tank
wet/dry with tons of biological filtration media (two chambers only)
8" of filter floss in the hidden area which contains the weir overflow
260W of PC with two fixtures each of which has one 10000K bulb and one 7100K bulb
300W of HQI-MH 140000K (two bulbs) The MH has been installed for approximately 3 months and I have the feeding, fertilizing, and lighting period protocols down as well as floating plant density such that no algae is present on the tank walls.


Please note that when I ordered the 300W of MH I also set up my sump as what I term a FW refugium.

The flow process through the sump is in the first chamber coarse mechanical media, fine mechanical media, bio balls, and, in parallel under the bio balls, ceramic toroids and ceramic cylinders and in the second chamber at the underflow from the first chamber sintered glass.

The first and second chambers of the sump are aerated.

The second chamber is illuminated with 75W of HQI-MH and has floating or other non rooted plants.


The question here is that I have approximately a 1'x1' footprint area and 1.5' height next to my sump in which to place a CO2 generation facility so what should I install?
(Please note that I have researched Fizz and do not believe that it will work.)

Thanks
Ron Jones

you can surely try co2 but it will prob be gassed out by the wet dry. i would try and seal it up as much as you can then add the co2 to the intake of the pump putting the water back into the main tank.

Ron,
What are your pump specs (gpm or gph?)

Why the wet/dry filter and refug. idea? Just curious?

wet dry get bio filter. very under rated in fw tanks. refug for lack of a better word helps with water quality. though for the most part i see them on tanks where they cant have plants in the main tank. it sucks up nitrates and other things out of the water.

I believe based on my current configuration and the head loss curve for the pump approximately 15 GPM.

mp: just one of my experiments which, so far, has not resulted in one of my adventures in fish keeping.
[1] I hoped that algae on the wood and rocks (limited patches) would go away and that the algae would grow in the sump.
This is occurring.
[2] Nitrate reduction.
Just had to check it out and the reduction of nitrates is occurring.

Yes but I was attempting to get the nitrates below 5 without RO water, am still experimenting but believe that I will get there.

Thanks

Can I just ask why you are running 14k lamps in your MH fixtures?

WD:

Just one of my experiments.

It seems like the gurus' knee jerk reaction is that anything above 10000K is for SW and I am going to check it out.

As I am certain you know the K value is based upon black body radiation.

Please refer to the 2nd chart at
http://en.wikipedia.org/wiki/Black_body

In 6 to 9 months I anticipate purchasing 20000K bulbs and trying them.

Hmm, it will be interesting to see the results. I'm sure 14ks are still better than pure actinics or anything like that anyhow.

Yes but qualified.

It seems to me like every time a question is raised concerning 7100K bulbs and FW the response is "oh no: those bulbs are only good for SW".

Some of the literature suggests differently* and I experimented.

Hence 2 - 10000K bulbs and 2 - 7100K bulbs in my PC's.

*The 7100K spectrum assists in chlorophyll production.
