Question About Starting Aquarium

[Ali]

how many gallons is the pond going to be?? im not so sure i would invest 40,000 in a skimmer either lol. thats a ton of cash for that. you could get 50 top line skimmers for a fraction of the cost, maybe less effective and time consuming, but that leaves more money for other things. be sure to post some pics of the pond, cuz i dont know bout you but im lookin forward to it!

I know,

I'll be sure to take pics.

If you are housing a bull shark, you'll need a pool size that will require at LEAST one of the large RK units - if not two. Higher numbers of small skimmer aren't worth the time. I won't get into the science of why they won't work.
You'll also need a set up of large sandfilters. Keeping a tank that size will take up about 20 hours of your week - not to mention a TON of physical labor. If you don't have the money or time, then you'll never be able to afford the rest. Massive amounts of food, water changes, keeping up large scale filters and the like are all part of keeping large bodied sharks.

None of the skimmers on the reefcreations link are going to be even close to large enough for you.
