Today was the first day I had the reactor running for a full photoperiod without messing with it - it is definitely working! When I was using the ceramic in-tank diffuser, I was able to get the drop checker to a nice pale green -- I left the CO2 flow rate the same when I hooked it up to the Cerges' reactor.

Came home today to gasping fish and a pale yellow drop checker! Needless to say, the flow rate is now cut back significantly (and added an air line/pump for the night!).

1) to reduce the splashing noise, and 2) to make sure there were no ways for the bubbles to escape.

on the 10" it was about 4-5" covered at bottom with sponge and bubbles still escaped. on the 20" i have no sponge in it, some of the previous posters don't have it either and they have good results so far.

I'm running about 4 bps into my 20" and I'm not getting any bubbles in the tank. Watching your video I see you have some large bubbles at the top of the reactor jumping around. Those bubbles look like air, not CO2, so I wonder if because you just installed it that the housing hasn't completely purged atmospheric air out of it yet.

I run mine with a Mag-5 pump full out, which is supposed to be 250 gph, and it looks close to that. I have fine bubbles in the housing but they're tiny, almost invisible. Some do actually make it into the uptake pipe, but by the time they reach the spray bar, they've completely dissolved.

I'll try and get you a video as soon as I can get to it. Probably tomorrow night.

i did installed it today and after running it i did let all the air go out by turning it upside down while it was running and i waited for all the remaining air to get dissolved before i turned on the co2.

maybe am running it at higher bps. if the mist doesnt stop i will try adding some sponge in there.

I wanted to thank everyone on this thread for this, I also got tired of the 7-Up looking water so I decided to make one last night. Got it hooked up this morning and didn't adjust my co2 and I noticed my drop checker change really quick, it used to take about a couple of hours before it changed to a light green color using my diffuser. I continued to monitor for the next couple of hours and started to notice the drop checker changing to a yellow color and I quickly dialed back the c02. This works really well my plants were pearling like crazy, no more 7-Up looking water, very efficient I went from 5bps to 1bps and quiet.

I just built one of these reactors, I don't have it up yet as I still have to get my co2 tank re-filled. My question is, if I use bio media in the housing, will this add to the biological filtration capacity? It seems to me like it would help, but I haven't been able to find much info on this..

I am using this filter housing:http://www.lowes.com/pd_89378-59019-WHKF-DWHBB_4294822071_4294937087_?productId=1201345&Ns= p_product_qty_sales_dollar|1&pl=1¤tURL=%2Fpl_Water %2BFiltration%2BSystems%2BFilters_4294822071_42949 37087_%3FNs%3Dp_product_qty_sales_dollar|1&facetIn fo=

Thanks!

I don't see any reason, given appropriate bacterial growth surfaces (bioballs/ceramic rings/etc), that the reactor wouldn't add to biological filtration.

Essentially, it's just a canister filter (driven by an external pump instead of internal impeller) so bacterial should colonize if they can find the real estate to make it their home.

The only reason you might want to reconsider aiming for this, is it can end up impeding the flow once it gets gunked up - but if it's placed after the main filter then it should take a while. And if you're using a clear housing like the one you linked to, you'll be able to see when it needs cleaning.

That's the large housing isn't it? You might be able to use ceramic media in it and get some bio action that way. I've never seen actual proof that CO2 impedes bacterial growth in the reactor systems. Maybe someone with a bio background can chime in here with some empirical data.

One thing I *do* know is that I bought that exact same filter, and returned it. It's the length of the can that allows gravity to work in your favor when dissolving the gas, not the width. I made the same mistake. Now, if you added media to the can, it *might* help dissolve the gas more efficiently due to eddy currents.

Good luck

Thanks! It will be placed after the filter and it's clear so I'll try it out.

m00se, thanks for the info, I'm going to go with it for now as I've already got everything glued up. I'll post back once I get it running as to how efficient it is at dissolving co2.
