First Tank - Ideas On Size For The Location

IN another post you mentioned avoiding Eheim Thermo filters - I just wondered why when they seem to reduce the kit count a little?

This was a problem I personally discovered. I'm in the USA and Eheim really only widely distributes the Pro II and bigger models here. I wanted one of the smaller "Pro" models and was doing a nationwide search to find one. I found a dealer in California who had some and had a distributor that she knew. When I indicated I was interested in one of the Thermo models, the distributor tipped me off to a problem they were having: The temperature sensors used for the heater could be thrown off if there was salt in the water. Now I do not recommend that people ever use salt on a normal basis in a freshwater tank, but there may come a day when there is some salt in there by accident or when one wants to use salt for medicinal purposes. So I ended up agreeing with this distributor person that the Thermo version of Eheim's filter line was not for me. The salt sensitivity thing did not sound to be a temporary problem.

So I had to go back to the books on how to not have a heater in my tank and the Hydor Inline was what I came up with and its been great, although of course not as neatly packaged as the Thermo Filter would have been if it had worked right under all conditions.

I wonder which way the salt influenced the temperature - did it cause it to rise or fall? I also wonder at the mechanisum is whereby the salt is causing the temperature sensor to mis-read - conductivity, density,... and if this sensor technology would also be used by the Hydor?

No, the Hydor heater is totally behind glass, just like a traditional test tube heater, just in a tube shape inside the Hydor plastic case. The Eheim Thermo device is a metal sensor unit sitting directly in the water below the filter trays I believe. WD
