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
4 ATI Blue Plus
3 ATI Coral Plus
1 ATI Purple Plus
10K – 14K – Crisp white with just a hint of blue
4 ATI Blue Plus
2 ATI Aquablue Special
2 ATI Purple Plus
For aquariums with a lot of LPS corals, a True Actinic bulb can be used in place of Purple Plus to provide enhanced pop in coral color.
