Would an aluminum coil system with icewater running through it to cool a rez cause any problems in a DWC. Corrosion, or any specific problems anyone can think of. Peace

At pH in the 5-6 range you're going to get tons of corrosion and Al in the water... welcome to the fun world of nutrient lockout...
Plastic tubing only!
