AC150 Causing Too Much Co2 Loss?

I have the Hagen Co2 system and an AC150 on a 10g tank. Would the water agitation caused by the AC150 cause too much Co2? If it does, how do you guys minimize the agitation?

Thanks,
Sly

Yeah you are going to loose co2 with that setup, but I've been using this setup on my ten gallon for 4-5months now with 2 20W "energy savers" bulbs and plant growth is good. Not as fast and as my 55 gallon and growth is smaller, but it's kind of nice actually not having to trim plants weekly.

The key is to get the water level as high as possible and to turn down the flow. I have mine turned down halfway and the water up to the bottom of the overflow of the filter. I've never really been inspired to try (kinda leaving well enough alone), but I think others have attached filter floss on the outflow as well to help minimize the splashing.

Also do yourself a favor and ditch that little bottle that comes with the hagen co2 and replace it with a 2L pop bottle or equivalent. You will be glad you did!

Sponges! Others have attached sponges to the outflow to minimize splashing.

I don't think you need to ditch the gray plastic chamber that comes with the Hagen unit. it should be fine on a 10G.

I use a 150 on my 10gal too. I put a piece of plastic over the outflow to direct the water downward instead of across the top of the water. I dont think i lose too much Co2, i still keep 20+ppm with DIY. U will need a powerhead for water movement tho, 150's wont move the water around enough.

How necessary is having a powerhead in a 10g tank?

Any recommendations for a small/discrete powerhead that does the job for 10g?

Thanks

I don't think you need to add a powerhead. The AC should provide enough water movement on its own.

Well u might be lucky, and get away without a powerhead. All my tall stem plants covers the outlet of my 150, so the flow doesnt reach more than 1/4 of the tank, hence why i have an additional powerhead (actually a small internal filter) to move more water around.

I"m probably going to use foam or a suggestion mentioned above since my water evaporates pretty fast.

Im getting about about a bubble per 2mins. This seems low, whats teh normal bubble per minute for the Hagen?

Being a newb, should the bubble go up to the surface and pop? I have no idea what should happen so I got to ask.

Thanks for the help!

the bubble rate seems very slow. I get more than 1 bubble per second from my 2L DIY bottle.

Really? It is only for a 10g so I don't want to have too much bubbles. It actually has risen to about ~20secs per bubble now.

For anyone with the Hagen co2, whats your bubble rate?

I get about a bubble every 5-8 seconds...i usually have at least 5 bubbles on the ladder at all times. I am also using a DIY mix and not those packs that come with the hagen unit if that helps any.

Are you using the same canister? Perhaps it takes time for the bubble rate to increase.

Yes im using the same canister...I had bubbles instantly once i put the lid on the canister. it took about 30 minutes to get my first bubble and they have been constant ever since. although it took a day or so for the bubbles to go through the whole ladder at first thay would get 1 or 2 steps up and then stick and build up untill the bubble overflowed into the tank..now they make the complete journey through the ladder.
Also ive only had this running for a little over a week now..so I would look into your recipe. Are you using the little packets for the canister or the DIY method?

I am using this recipe for the hagen canister at the moment....

Fill it to the bottom line inside with sugar and then to the top line with water, then add 1/4 teaspoon fleishmans yeast, and 1 teaspoon baking soda. I dont shake or mix it either...so I dont know if that makes a difference?

Might want to try that out if you havent already.
