Replacing the Stock Light

I recently decided to upgrade the lighting in my Topfin 5-gallon shrimp tank. The original light wasn't cutting it for my plants, so I purchased a new, higher-output light from Amazon for around $17.

The new light features a handy timer function with 3, 6, and 12-hour settings, a valuable addition for consistent plant growth.

To install the new light, I first needed to remove the existing Topfin hood. This involved carefully breaking off the plastic clips securing the lid, which was surprisingly easy to do by twisting them off individually.

Securing the New Light

I used 3M Command Strips to mount the new light. I applied six strips for extra security, covering some areas with waterproof tape for added measure.

The Command Strips were previously unused, and I found them incredibly useful for this project. I went a little overboard with the tape, but it ensured a strong and secure attachment.

While this isn't a high-end light (it cost under $20), it's perfect for low-light plants like water wisteria, mini salvinia, java fern, and anubias. The improved lighting provides a noticeable enhancement to the overall aesthetic of the aquarium.
