<p align="left">Nitrifying bacteria will die at 120<font face="Symbol">°</font> F (49<font face="Symbol">°</font> C)</p>
<p align="left">Nitrobacter is less tolerant of low temperatures than Nitrosomonas. In cold water systems, care must be taken to monitor the accumulation of nitrites.</p>
<p align="left"><font face="Arial" size="3">S<font size="3">o Gregory you can see that the optimal conditions for building bacteria(cycling) is 70F-90F. However bacteria will <font size="3">survive</font> above 40F. <font size="3">This means you can cycle fairly quickly in the warmer months<font size="3">, build the bacterial population and keep them as a slightly declining population over the colder months. The fish themselves feed less in c<font size="3">older temps, so you'll require less bacteria for converting Nitrogen, and as it warms and the bacteria expand again the fish can feed more. This way you can work with the AP over the seasons successfully<font size="3">.</font></font></font></font></font></font><a style="cursor: pointer;"><img src="http://www.bkserv.net/images/Smile.gif"/></a></p> Thank you for the encouraging…tag:aquaponicgardening.ning.com,2013-05-23:4778851:Comment:4783412013-05-23T00:39:08.659ZGregory J.

Thank you for the encouraging news Harold! The last 3 days the water temps were 70,72 & 73F. How do people raise cooler water fish ( trout, perch) if one needs temps in the 70's to have your bio-filter healthy?

<p>Hi Gregory,</p>
<p>If your temps are high it won't be long before you see the system cycled. With ideal temps it can take as little as one day.</p>
