I have a 1.5 months old tank with 10 frags - 30% SPS and 70% LPS. So, it's too early to tell. Overall trying to avoid aggressive corals like softies and euphyllias, entirely.
My tank is designed in three sections (longitudinally) -
- High Light, High Flow: roughly 6 ft × by 1 ft (width) x 2 ft (height) where I have high lighting ( 3x 6 ft ReefBrite XHOs - 2x Blue, 1x 50-50) and high flow (1 Wav)
- Low Light, Low Flow: roughly 6 ft x 0.75 ft (width) x 2 ft (height) where I have lower lighting (2x 6ft ReefBrite XHOs - 1x Blue, 1x 50-50), and low flow ( in-tank Tunze Filter)
- Frag area: roughly 5 ft x 0.25 ft (width) x 2 ft (height) that receives sunlight for 10 hours in a day ( during summer), 8 hours in a day (during winter).
Because of my tank's newness, the light penetration is really high, and the frags can't handle the ReefBrites even at 15%-20% intensity. Sunlight is the only thing that they like.
