I'm starting to get the parts for my Cerges reactor. I see that the water filter housings are 2 1/2 inches or 4 inches? Does it matter?

Also, does it matter what housing to get? Prices seem to be all over the map, all seem to have a small percentage of one star reviews talking about cracked housings and floods, even top brands like GE and Culligan have reports of cracked housings.

You almost definitely want the 4" housing. As far as brand, I would think any reputable one will be fine. You're going to find negative reviews on anything you're trying to buy, so I wouldnt let that dissuade you.

Do you mean a housing 4" in diameter or one that takes the 4" internal filter?

I've looked at a lot of photos and since I know the filter housing is 10" tall, man, they all look like they are about 4" in diameter, which means they take the 2 1/2 filter. (And of course we never use the filters!)

For example, the Culligan WH-S200-C uses a 2 1/2" filter Culligan WH-HD200-C can take a 4" filter.

I'm sorry, I didn't realize it was measured by the filter diameter. In that cae, you want the one that takes the 2.5" filter.

I went with is the 4.5" x 20" housing. The more contact time the CO2 has with the water the better. I went with the filter in the link. It's really a well built housing and I am happy with it so far.

Oddly enough, when I bought mine only a couple months ago, both the 10" and 20" models were $10 less expensive.

Good to know!

I thought clear was better so you could see it working or not working. Then again, I guess if you are getting bubbles in the tank you know it isn't working.

I would have preferred clear too but the price was almost double and, even though I'm great at justifying unneeded money spent, I couldn't justify this one! :)
