Hey Micky looking to make a trade if you would like. i have this black china box led https://www.amazon.com/Galaxyhydro-55x3w-Dimmable-Spectrum-Aquarium/dp/B00INM0J1M Used it for 2 years. I also have a refractometer. it's about 5 years old, shows wear but still works! I was thinking the Hydor Professional, and 24" nat Geo light?
