I have had the lamp attached to the RK2 and it is still flickering on and off when at the cutoff temp. I am going to email Digital Aquatics to see what can be done. I haven't dealt with it in a little while now because life is rather busy.
I did make some new RHF 2 part last night. I was running out. Being a teacher I have the next two weeks off so will be doing some tank maintainence.
I have a ton of plans for the tank. Dosing pump for Alk and Calcium, frag tank, new skimmer, possible kalk reactor to help with pH at night, and bigger chiller (possibly DIY). But all of that is going to wait until after I get a fishroom. The city has the corrected plans for the new garage so hopefully permits next week. Construction probably won't start until after the 1st of the year, but should be done by May. Which means that during the summer all the above will at least be started.
