So this was my first DWC and in three short weeks I'm on my third version. Reservoir holding 17gal 2 large air stones and one small...Most versions I saw during my research utilized a submersible pump for the top feed and added ice bottles to control temps
So in v1.0 I decided I would use an airlift pump to run my top feed worked like a charm... No added heat to my reservoir and the bonus of only one pump for the system and Girls being fed from the top.
Then I ran into the issue of high water temps just from the ambient temps in my room.
So along came v2.0 for which I built a 12v closed loop res cooler using a Peltier cooler and a digital temp controller... In testing I found that closed loop didn't cool fast enough. So along came v3.0
In v3.0 I am running the Peltier cooler feed directly from the res and return into the res... I am currently maintaining 68 with hopes to reach 63...
I will post some pics and plans soon!
