If you want to get into saltwater reefs you really have to do your research. I thoroughly researched the hobby and read some of the top selling books for 3 years before I decided to actually do it. Then I spent another 2 years designing the system which was a dynamic process since the technology was still evolving while I was designing so I had to make changes as I went along. I followed the efforts of several hobbyists who were building large systems and were documenting everything they ran into online. I incorporated certain features that they used that I liked into my system and made sure to avoid any pitfalls they had run into. Also during all this time I was slowly acquiring the tanks and materials I would need, always looking out for good deals. Once i had the design down, I spent the next 18 months slowly building the system. Back then I was commuting 3 hours a day to and from work and we had 2 baby boys to take care of so I was only able to spend maybe one weekend a month on the project.
Anyway, even after all that research and designing, I still had to make adjustments to the system after it was finally up and running. My original method of water filtration was by means of an Algal Turf Scrubber which I designed and built myself (the manufactured ones were between $1000 and $2000). In theory it was a great idea but in practice it could not keep up with the nutrient load and required too much maintenance. So I finally took that offline after a couple of years and caved in and bought a high capacity protein skimmer.
Now after running for 9 years the system pretty much takes care of itself. Except for cleaning the glass which is a real pain because the main display tank is actually acrylic and scratches easily. Also there is a type of coraline algae thats calcium based that grows on reefs and is very pretty. But it also grows on the tank and is very difficult to scrape off, so that's my only bi-weekly chore. I usually let it go a month but then I pay for it because the longer I go between cleanings, the harder it is.
I'll try to take some pics of the plumbing and some of the different components of the system. My friends always used to tell me I should open a museum and charge admission just to see the technology involved.

It's not high tech pretty because it's all home made but I tried to utilize "natural technology" as much as possible in a not-so-natural environment. The things that exist in nature are infinitely greater in efficiency than anything man can come up with as far ecosystems are concerned. The reef hobby used to be full of high tech expensive gadgets trying to keep captive reefs healthy and alive. Nowadays the more successful reefs try to reproduce a natural environment as closely as possible.
