I'm in that camp. Had the Marine 3.0 for almost 3 months and now switched to 2 bars eith 3w LEDs and a better distribution of wavelengths: 8/36 LEDs in white and the rest in blue/cool blue/UV.Both the stock lighting and the Marine 3.0 are likely underpowered for BTAs. While the Marine 3.0 is definitely better than the stock light, they are both really just adequate for low light soft corals and LPS. I’m assuming you have the 32w version (unless they make a smaller one?), which on paper seems decent, but you’re not going to be running all channels at 100%. I n top of that, it’s using very low wattage LEDs (likely less than 0.25watts) which comparatively produce far less PAR per watt than larger 3 or 5 watt LEDs. 32 watts of even 0.5 watt LEDs is going to produce much less light than 30watts of high quality 3 watt LEDs (likely much less light than even 15watts of 3watt LEDs). Plus the light is spread out across the tank instead of concentrated into a single point. There are plenty of people here that have used these lights only to replace them because they were inadequate for more light demanding corals/anemones.
The light spread in the Marine 3.0 is amazing and the colors are visually appealing--might be a top choice for fish-only tanks.
