Best ATI Bulb Combinations for Your 8 Bulb Fixture

It’s easy to spend hours deciding which T5 bulbs to use over your tank. It’s challenging to visualize how your combination of bulbs will look in your fixture. While a lot of aquarium lighting is based on personal preference, here’s a general guide to help you select bulbs for your 8 bulb fixture:

16K – 20K – Bluish white with a noticeable blue and red under-tone
5 ATI Blue Plus
2 ATI Coral Plus
1 ATI Purple Plus

12K – 16K – Cool white with a noticeable blue and red under-tone
