I like the idea of pumping the CO2 directly into the return of the filter. I have too much stuff hanging in the tank already.

Does anyone know of a diffuser that will that will fit in the return tubing of a Fluval 407?

One more question.
Does anyone have experience placing the CO2 probe into a HOB filter. Again, want to limit the stuff hinging in the aquarium.

Thanks,

Fluval offers fittings to incorporate a co2 reactor in the return hose.

I've been reading a lot about CO2 injecting, and the risk to plants and even fish if done incorrectly.

I travel and my wife is in charge of the fish while I'm gone. She does a good job, but if something is going to go south it will happen on her watch. So, I don't want to load her up with stuff to do and monitor.

It seems that a simple way to do this that might the plants just a little kick would be to use half (quarter) of the recommended Flourish dose every day.

Can anybody comment on the pros and cons of that approach? Aside that the plants will not grow as fast.

Did you mean Flourish Excel? Flourish is the micronutrient mix product that Seachem offers, so it won't be a substitute for CO2.

If you did happen to mean Excel, then it's not as effective as CO2, and is relatively expensive in the long run (there's also the hassle of needing to dose it everyday).

Excel, yes.

I'm in the middle of trying the upside down bottle method in a 180 gallon aquarium. Got a mason jar and wedged it in the corner between the acrylic and an overflow pipe. see first photo.

Half bottle lasts about 9 hours. The pH went from 7.4 to about 6.8. After two days (now into 3) the fish look good, the plants show noticeable growth. I have some green algae on the driftwood. Going to buy some Oto catfish today. I already had algae on the gravel.

I angled the Fluval outflow towards the jar to create more water flow.

There is a little residual CO2 in the jar at the end of the day, which is still there in the morning. I'm guessing there is not enough flow in the bottle at that level to absorb CO2 from the jar. First night I sucked it out. I left it alone last night and the fish look good this AM.

My new FZONE Pro Series Aquarium Dual Stage CO2 Regulator comes tomorrow. The plan is to place the regulator on a timer and fill the jar before the lights come on in the AM.

If I want to get more aggressive I can easily make the switch to inline CO2. My plan for that is to get an Eheim Classic filter and run the CO2 through the return line. You can see that I have lots of filters: Fluval 407, 2 Aquatec 30-60s, and a sponge. There is already a Fluval UV filter hooked ups to the return line from the Fluval. I really don't want to try to add another line there. That's the logic for getting the Eheim.

The second photo shows that the jar sits in the shadows and it hardly visible.
