I have been trying to clean out all of the algae I can find in my tank, an almost impossible job. One problem is that algae is growing inside the viewtainer part of my venturi reactor, and it's construction is so flimsy that I can't do an effective job cleaning it out. So, I made another one, with some changes. First, I discovered the secret to finding viewtainers in the stores. Orchard Supply Hardware keeps them in the tools section, where it is very easy to overlook them, but after searching the entire store I found them. Only $2 for a 2" diameter by 6" long version.

So, here is what I ended up with:




This one is made from my Maxijet 600 powerhead. I have the outlet going into the side of the top of the viewtainer instead of down thru the top to an elbow. It is a bit off center on purpose. The purpose is so I can use the existing suction cups on the powerhead to mount it making it much more securely mounted. Next, I have the CO2 inlet coming in thru the side of the viewtainer instead of thru a long tube down from the top. This makes it easier to brush out the inside. Finally, I have a coarse sponge on the inlet to the powerhead to keep baby shrimp, etc out. Tomorrow I will see how well it works.

Edit: It works just fine. Smaller CO2 bubbles coming in, since they go thru a little airline connector, and it starts producing a little CO2 mist almost as soon as it starts up. It quickly builds up the CO2 to around 40 ppm with no problems at all.
