A clip-on fan that cools tank water by 1-3 C via evaporation - cheapest solution for warm-climate temperature control.

For: Both $15-$100
📖 Overview
Small clip-on fans mounted on tank rim blow across water surface. Evaporation cools the water 1-3 C. Best for tanks fighting mid-summer heat when a full chiller is overkill.
🛒 Buying Guide
For temperatures above 30 C, a full chiller is required. Fans also increase evaporation requiring frequent top-off.
