Great for smaller tanks!

The Aquablue 50:50 is a versatile and deeply penetrating light source which is great as a standalone for smaller tanks or used in larger setups in conjunction with the iQuatics Blue Plus or the Actinic range.

With the Aquablue 50:50 you can increase stocks safe in the knowledge that the mixed spectrum will provide maximum PAR for the ideal coral growth. Your aquarium will be bathed in an attractive blue-tinted light and any yellow tints will be reduced…improving the overall look of your setup.

Useful facts!

High output T5’s are a better choice than the regular T8 because increased water penetration means greater efficiency. You gain illumination and your tank benefits from improved growth and enhanced beauty.

Because the iQuatics Blue 50:50 is one of our most popular fluorescents to date, you know that you’re making a sound choice. Combining the phosphors of a Blue Plus tube with a 10000K full spectrum daylight bulb, the iQuatics Aqua Blue also works well as a supplement to metal halides or when used together with the iQuatics Marine White 14000K.

Fantastic and stress free ordering. Bulbs had arrived VERY well packaged within a matter of days. Coral's had "popped" within a matter of hours and loved the new lightening.

Would definitely order again in future.

50:50 100% for me – Review by Catflaps (Posted on 28/10/2011)
I have a 110 litre planted tank, which came from ebay with a single T8 attachment. as it was 18in tall the lighting really wasn't cutting it. I upgraded to T5 and as the Aqua Blue 50:50 were cheaper on the website than the shop bought ones I was looking at, I took the plunge. WHAT A DIFFERENCE, I now have to look at CO2 solutions as the plants are outdoing themselves and my fish look stunning! Great value and amazing quality. I have already set my bulb service reminder for next year!

Posted by Keith on Tuesday, 27 September 2011


Does your buy 2 get one free offer on bulbs only work with the same bulbs? eg if I buy 1 blue + and one 14k can I get another bulb free or do I have to buy 2 of the same bulbs for the third?

    You can mix and match the t5 tubes and still take advantage of the Buy 2 get 1 free offer. The cheapest tube will be the free one.
