Testimonials

Mt. Prospect, IL

Thank you for the great service and quick shipping on my RO/DI filter order. Everything arrived safe and sound, and was much better than I was hoping for. Nice quality and very complete. Thank you! I couldn't be more satisfied. You can certainly expect an order in the future, and high recommendations from me across the net. - Kevin M.

A few nice words

I wanted to thank you for sharing your knowledge and expertise. I purchased a 55 gallon saltwater aquarium and used your pages as the reference. My fish which came with the tank are doing well. The setup went brilliantly following the steps of washing the sand, cleaning the tank, placing the sand in first, using the trash bag with the platter and bowl gave us instant gratification. Cleaned the rock in newer water and placed them. The numbers are all great since we used most of the old water. As long as we followed your plan everything worked out great.

My wife and I have never owned a saltwater tank and you could imagine the surprise on the face of our kids when they saw the tank, they are 6 and 4. I can honestly say we couldn't have done it if it were not for you sharing your knowledge. Thanks a million. You're the best! - Mike R.

Thanks Marc...and my tank made it just fine through my 8 day vacation btw...my clowns really enjoyed the regular feeding, they were so fat they could hardly swim. I am sure that added to the cyano issue...loving the Eheim feeder chimney you made for me...as well as the RO/DI system...fantastic !!!

One of the reasons I (and I'm sure many others in the reef aquarist community who pour over your articles and plans) admire and respect you, beyond your clear technical expertise and unselfish willingness to offer help and advice to others, is your willingness to share your build mistakes, to show examples of where your execution didn't match your vision, and what you would do differently - that's rare. You're a tremendous resource to us, and much appreciated. - John D.

I ordered a photo box from Marc. Really just played with it about five minutes inbetween things I have going on and snapped a few shots. I need to practice a bit more, but this is what I got in those 5 minutes! :-) Thank you Marc! I'm going to love this! - Dewana R.

Barrington, IL

I absolutely have to applaud you. The [RO/DI] system you put together, coupled with your online instructions, really is outstanding. Many thanks for providing the system. It's going to make a huge difference. Everything worked out beautifully and the filter is now mounted and in a convenient place for easy service. This major upgrade has absolutely eliminated the hassle of making DI water. - Gary P.
