Alright I think I finally understand how the sump is put together just one more question about it which section would the macroalgae go in?

And is there anything special I should know about the lieutenant tang or snowflake eel?
snow flake eels can ether be a great fish that leavs every one alone or a fish that will kill all your fish. just feed A LOT at least one big mel a day and eels like snakes you should see a big lump in ther belly after they are done feeding. i would feed untill the eel is not interested anymore.

oh and the tang is a peacefull fish except with other tangs. i would feed it a varity of meaty foods and also feed with a veggie clip to give it the veggies that will make its color pop and suport its immune system.

Alright good to know and is there anything you use to attach live rock to each other so the fish don't knock them over?

Hi,

if you take your time, turn and twist the rocks that need to stack...you will feel them "lock" into place, give it a good wiggle to be sure it won't move. You can create some awesome columns and such using black pond foam, but the rock has to be dry before you can do that, meaning you can only do it with base rock
, you will kill live rock if you do that.

Alright and what section of the sump does this macro algae go in?

It all depends on your sump design, which I believe you are working on. My sump had three chambers...the skimmer and hose from the top display to the far left chamber , the return was in the middle chamber, and the far right chamber was my refugium section that fed into the middle return section...the refugium section is where the macro algae would go.

Since you plan on a FOWLR...There are also decorative macros that can go right into the display, giving color and contrast to the rocks, but tangs have a habit of eating it up, so you would have to get something they wouldn't find yummy. You would have to do a little homework to see which macros those would be, and if you like the look of them. Check out Golf Coast Ecosystems

That's where I thought it would go just wanted to make sure and yeah I'll check it out. And also what can you tell me about the reverse osmosis and overflow box?

Reverse osmosis is a water treatment procedure that removes dissolved contaminants in the water. Most typically, reverse osmosis is combined with deionizing cartridges to produce reverse osmosis-deionized water, abbreviated as RODI. It is important to use this kind of water because as tank water evaporates it leaves salt behind, so the salinity increases. To prevent this it is necessary to add water to make-up for evaporation. However, tap water, while having contaminant levels below toxic, if used to make-up for evaporation, will also evaporate, leaving the contaminants behind. Gradually, the contamination level increases until it becomes a problem. Tap water also has silicates and phosphates in it, which will support undesirable algae growth and diatom infestation. You can make you own RODI with apurchased unit, or buy at at some lfs as well as at WalMart. If you system is onb the large size I would spring for the RODI-genrating unit since the per gallon cost will turn out to be lower in the long run.

The overflow box is one of the ways to move tank water into an external sump. There are many types, each with its advantages and disadvantages. My large tank has bypassed the overflow box completely by having drains drilled out on the bottom of the tank (so called "reef ready"). My 40 gallon unit was not reef-ready, but I drilled a hole and fitted an internal drain that I got from glass-holes.com (they sell kits, drill bit, drain, builkhead fitting and all in kits). You can find overflow systems on almost any aquarium supply web site, including this one.

Are overflow boxs necessary or can I just put an intake valve in the tank and run it start to the sump? How often do I need to add the reverse osmosis water?

I'm not clear how a valve would work, never seen one. The rate of evaporation depends on a variety of factors, including tank size and surface area, open or closed top, water temperature, etc. To give you an idea, in the winter, with the room temp at 69 and water at 80, with an open top I replace about 2-3 gallons/day in my 220 gallon tank.

Like a hose basically with a pump that just sucks in the water from the tank down to the sump. Mines a 135 it will have an open top and I'll probably keep thewater at like 80 degrees I don't know if any of thathelps but should I just check the water every few days and add it if needed

You never want a pump to remove water from the tank - sooner or later it will either fail, and the return pump will cause your dt to overflow, or the return pump will fail, and your sump will flood. Divorce lies in that plan. To maintain your salinity fill the tank and sump, get everything going, then put a piece of colored tape on the outside of the sump at the water line. Whenever the level falls just add RODI to the sump until the water level comes up to the mark. Take a look at sump designs online. They all are designed to prevent flooding and make life a little bit easier.

You'll cause a flood trying to do it that way. You'll never be able to match the flow equally between two pumps well enough to trust it.

The overflow box works by siphonage, and you set the siphon break just below the surface - it's then automatic. If the power goes out the siphon breaks and flow stops...no flood.
