Non quartz uv sterilizer operating at 68 degrees?

[scragman]

I have a 25IL non quartz uv sterilizer that says not to use at temps less than 72 degrees. If I use it at 68 degrees, how much will it decrease the effectiveness?

I have no idea, but is it possible to replace the sleeve to quartz so it can be used at lower temps?

If it is non=quartz, what is it? Regular glass cut down the UV so much it is useless.

As for the temperature, I have no idea why it is 72 F and not 71.49F or 68F. Do you have a link for the item? Who made it?

Here is a link to instructions regarding not operating non quartz sleeve uv sterilizer in less than 72 degrees: www.aqualogicinc.com/products/sterilize ... ctions.pdf

The best thing to do is to call the AquaLogic and ask them directly.

It seems like it is not really "non-quartz" but one that does not have the quartz sleeve. If you read the documention (your link above), it says it is one that is not "quartz-sleeved," and not "non-quartz." The bulb is still the same, just that the UV bulb is in direct contact with the water it processes, instead of indirectly thru a quartz sleeve. See the difference here, and how your tem mislead us?

Basically, my guess is that when the bulb is in direct contact with the water, the low temperature can cause the bulb to crack or to malfunction. Florescent bulbs, such as the UV bulb in these gadget, has a temperature sensitivity due to the use of mercury in there. When the temperature is too low, it often flashes on and off due to the low vapor pressure of mercury, damaging the electrodes. and cause premature failure of the bulb.
