I will keep this thread 'alive' for others who want info on this filter and how it performs over the long run. I did purchase it & set it up the other night, very simple. Filled the media baskets with SeaChem Matrix (12L). This pump is silent! The reviews I read said it was quiet but even I was impressed. Since the tanks sits as a divider in the living room with the couch against one side it was important to have a system with the least noise as possible. It is very BIG though, luckily I was able to fit it under the custom wall/stand with about 1/2" of clearance on the sides. They say it comes with 14'9" of hose, mine came with 16'3" which made my day as I needed a few more inches than what was said to be supplied. I will be curious to see how the Matrix performs, some people have seen great drops in nitrate levels, other have not see any reduction. However none of the reviews have ever seen an increase in nitrates by switching to Matrix. I have also purchases the Instant Ocean Natural Nitrate Remover as well, but I am not going to use that unless the Matrix can not handle the job, which I will not be able to tell until the filter/system cycles and everything stabilizes. I will post back with updates if something comes up or at longer intervals to let you know if things are still fine with it or not.
