Replacement Fluval Ballast – Review by Steve (Posted on 29/03/2016)
I bought this Ballast to replace the broken one in my Fluval Profile light unit. It's a fairly simple job, straight swap. Works perfect. Saved buying a new light unit from Hagen.

Great – Review by t5 ballast (Posted on 23/09/2014)
Product was delivered quickly. I needed help with the wiring and iquatics helped me with this. Product works well and i would definitely use iquatics again.
Great item – Review by Snazzy (Posted on 12/05/2014)
This item is not the cheapest on eBay, but not the most expensive. My decision to purchase from this seller proved to be the best as the ballast bought was not quite the same as what I already had. So emailed seller for advise which proved to be invaluable. Such a nice man (shawn). So my rating for this item is 10/10. Item came quickly even through the bank holiday. Extremely well packaged. I would not hesitate to recommend this seller and will most certainly use again without hesitation. Thank you so much iquatics.
