Welcome to R2R! Looking good!I just want to say hello and thank you for the adding. I´m fron Argentina, aquarist since 30 years, use to breed discus fish and have freswater planted tanks. Yeas ago, I had marine fishes when I was a kid (I´m 49 years old). Now starting a reef proyect. My tank dimesions are 90 x 90 cm (35 inchs) base x 50 cm (20 inch) tall, around 400 liters (110 gallons) without the sump. The aquarium has 2 Hicrew of 100w, 1 pump Aqua Medic DC Runner 5.3, 1 wave maker Aqua Medic Eco Drift 8.3, 1 Skimmer Bubble Magus Curve 5. I thinking in put a Lifeguard UV filter. What´s do you think? Is it positive? I want to have only a few fishes but a lot of corals (long term). Here are a few pics. Best regards for all !
