The Arcadia Marine Blue Actinic promotes welfare of invertebrates.

For a marine aquarium to realistically represent reef life, it is essential to provide the best conditions for corals and invertebrates to thrive. Most important in this is the survival of zooxanthellae, a specific form of algae, which symbiotically assists the invertebrates to feed and remove waste matter. In nature, the sun provides over 100,000 luxlux (lumen per sq. metre). At depths of typically 5 to 10 metres, where many of the corals and invertebrates are found, the visible light to be seen, is basically only in the blue wavebands, thus the familiar blue appearance. All the other wavelengths, particularly reds have been absorbed and filtered out by the salt water. This remaining blue light is the light which invertebrates have evolved to utilise for zooxanthellae symbiosis.

The Arcadia Marine Blue Actinic lamp range has been created to provide the specific spectrum (400 - 480nm) necessary to achieve the blue chlorophyll absorption for zooxanthellae symbiosis to develop. This concentration of light energy in the so called 'actinic' range peaking at 420nm, is essential for the survival and good health of fish, corals and invertebrates in marine aquariums.

Another important element of the Arcadia Marine Blue Actinic lamp is the UV output present, which creates a very pleasant fluorescent effect on corals, invertebrates and exotic marine fish.

When used at night with no other lamps, the effect is of a dark moonlit night with the vivid colours of the corals and invertebrates fluorescing brilliantly.

When used in conjunction with the Arcadia Marine White lamp range, the high levels of light output create a most realistic marine reef environment. This combination gives the most natural and pleasant appearance and highlights the fluorescence and bright colours of the fish, corals and invertebrates, along with the correct spectrum output at the required wavelengths to achieve the reproduction of the symbiotic algae, zooxanthellae.

The Arcadia T8 Marine Blue Actinic is available in 7 sizes and is also produced in T5 sizes. T8 bulbs are the traditional choice for aquarium lighting

A must for good coral growth Review by keith
This size of t8s are becoming increasingly more difficult to get and so was pleased to see them on here. I have tried running my system with out them (halides only) which resulted in poor coral growth and recession on some. Warehouse post these quickly and safely. I received one broken from transit and I was immediately sent a replacement the next working day. (Posted on 12/05/2013)

Orders over £30 are Delivered FREE!

Providing none of the items in your order require pallet delivery or are excluded from delivery promotions, we will give you free standard delivery. You can still upgrade this service if you wish, and will only pay the difference.


Pallet Deliveries are different.

For items that have to be sent by insured pallet or other special delivery, these are excluded from the standard delivery offer and instead follow a different system. Pallet deliveries are split into 2 tiers: tier 1 and tier 2. Pallet deliveries take 2-4 working days and cannot be tracked.


For pallet deliveries we will contact you to confirm the delivery address and delivery day before releasing the order.


Please note that the pallet delivery service is a drop at kerb only service, the drivers are not insured to handle goods into homes and you are required to dispose of the pallet.


Pallet Tier 1

This tier is for solo tanks and cabinets, or other solo high weight products that we can't send by a normal courier. We subsidies the majority of the true delivery cost for these items to offer the best value we can. The shipping cost for these is calculated at checkout.


Pallet Tier 2

New for 2020! We are proud to announce we now offer FREE mainland UK pallet deliveries for Pallet Tier 2. Pallet Tier 2 is for the larger full tank and cabinet sets, such as the beautiful Juwel Rio, Lido, Trigon and Vision ranges.
