- Take a small piece of window screen and a rubber band and cover the exposed end of the airline tubing that is outside... keeps dirt and bugs out of the airline.

 

 - As Mark pointed out earlier, the higher CO2 that builds up in your home is not good for people, either... we are lucky here in UT that even if it is super hot (90+ degrees) out during the day. it cools off quite a bit at night. Be sure to open a few windows before you go to bed (say around 10 PM) every couple of days to allow fresh air into your home. You can keep even the A/C on, since the outside air at 10 PM is probably the same temp (or even lower) than your inside temp - so you won't make your A/C work any harder than if the windows were kept closed.

 

 

 

 

This option use a plastic "tee" to  put everything together -

 

 

 

This one just drill a hole into the outside air tubing for the ozone air output and then slip the outside tubing right over the existing skimmer intake airline (this is how I did it) -

 

Just make sure your connections are fairly tight so no ozone escapes into the ambient room air (ozone is bad for you)

 

 

 

When I did mine, I drilled a small hole into the outside air line (just be careful not to drill through to the other side of the tubing, you only want to drill a single hole) that was the same diameter as the output tubing from my ozone generator.

Then I just stuck the ozone tubing into the hole and used a little superglue to hold it in place.

Yes Kurt, you should worry. Low Alk levels are extremely hard on SPS. Chronic low Alk levels can also led to your sand bed breaking down or dissolving. Think of a Calcium reactor. Target PH inside the chamber is 6.0-6.2. This allows the media to be broken down and in turn add Ca and Alk to the display. Raise your Alk up to 8.0 asap.
