I just got this tank from another owner, and I cant tell what these organisms are. They are green on the outside polyps, with a purple inner circle. They are about 1/4 inch or 1/2 centimeter in diameter.
Here's one that's 4000k, or I think 240 watts. https://www.homedepot.com/p/Metalux-SHP-46-5-in-Black-Integrated-LED-Shop-Light-4000K-in-Cool-White-4SHP4040PB/306536396?MERCH=REC-_-pip_mobile-_-311264314-_-306536396-_-N
I am looking for a new light for my 55, but I'm pretty restricted on budget. Which light should I get? I was looking at the Finnex Stingray 2 48" or the Koval 45"-50". Are there any other lights I should look at or which of the two above should I choose? Thanks!!
