I found this video to be pretty helpful and like this approach. He kind of rambles but it's worth hearing him out.
I don't think you're implying it but I definitely dont feel you overpaid. Everyone has different things that work for them. On my last tank I was able to sell a lot of what was left when I lost my equipment to the hurricane. I plan on fragging more to pay for my equipment this time. Investing in equipment that will aid in growth and keep the PH high IMO is worthwhile.
I'm fortunate enough to live near World Wide Corals and see how they do things. In their main displays they have GEO's fed by the Sicce pump. I plan on copying their method of success.
Nice video Roggio! Thanks for the line on that. I think you know exactly what you're doing and am sure you'll be successful. Thats a very reliable option plus having wwc near by is priceless. Good luck with the build and happy reefing!
