I would like to congratulate you on your product (Ion Director ), I hope it will continue be so accurate in the long term, send my best wishes to everyone.
I would like to thank you once again for the great Mitras Lightbar 3 lamps. They provide a very beautiful and uniform light. A check with a light meter has shown that the lamps perform significantly better with the same power consumption as the previous ones.
That’s why I’ve dropped the original plan to use combination lighting for the new tank and only want to work with the MLB 3 lamps.
Everything is excellent.
I really must say that I am very satisfied with these superb lights.
Thank you for your fast and reliable help – I am always pleased to have chosen the right product and will recommend your products to others.
Again I am incredibly impressed by GHL’s levels of support 🙂
I will make sure to mention your super good support to all my saltwater friends and on the forums I’m using every day.
Thanks a lot, now I know where to put my savings…..

I would like to thank you and GHL for the super-fast repair.
This once again confirms my trust in GHL as a good partner for my aquariums.
First of all I’m very happy with the ProfiLux, it’s doing its job perfectly.
It is very pleasant to deal with you. Excellent products, superb service, brilliant responds!
