Venturing into aero cloning I’ve had the slow water temp rise from the pump no matter how long intervals are. I started using cooler sticks, but it didn’t last long enough. I needed a bunch of ice packs to cycle through, so I found this product and I wanted to pass it along since these are long lasting dry ice packs that you can custom cut or soak the entire sheet
Find it at Amazon
Sheet pack
Cut slowly and carefully down the center
Simple 5 min soak
It’s now ready for the freezer. They can be used the next day, but to be block firm give it 36 hrs
Now this pack is ready. And here is the water thermometer, ready ? WATCH
About 45 mins later you now have this
6-9 hrs later
and will be slow to rise back up but you can have chilled water for about 25 bucks. Now I’m only using one strip for 2 gall bucket. So larger reservoirs will need several or larger packs per cycle, but the package has 10 sheets (40 strips), so I believe it has enough to keep frozen while others are used per day, so there’s always a frozen pack ready to drop in. As I said this is better than fill up water ice packs and the blue coolant type, rapid plunge and long lasting chilled water. DO NOT use these packs in their natural packaging. The polymer will keep absorbing after thawed out in water, so make sure it sealed in another bag or remove it before it’s completely soft.
Update : BEST and SAFEST way to use these is vac and seal the pack in Foodsaver bags. I’ve learned the polymer keeps absorbing water after its thawed, causing it to leak out. Being vac and sealed prevents this.
I hope this useful for OGer’s having trouble w higher res temps to avoid dreaded Pythium
