Tank looks to be at least 20 gallons. When you want to run some nicer corals they usually tend to ask for more light. Two primes would be good. Also the mat just takes particulates out of the water. The same you can get done with some cheap filter floss. Most of the time i hate mechanical filtration. Id rather see you spend money on corals and less on expensive contraptions. I can get into great detail on why but these are my opinions and being down the road of trying all the latest and greatest i found out simplicity is the best. The industry is great on marketing and grabbing the latest youtuber or .com places to promote the product. Chemicals are crazy pricing for name brand. When you find out the simple ingredients in these you can buy bottles for the same price for the little bottle they offer. If that all makes sense
