200g starfire in-wall w/ fish room - gyre style flow

consumed reef

In Memoriam
greetings! new here, but not new to reefkeeping.

i am in the process of setting up a new ~200g display, sized 80x24x25. the tank was purchased new and was built with a starfire front and center overflow (optimal for wavebox). the overflow is 5" off the back wall so that i can fire a wavebox down the full length of the tank - at the back of the tank. the flow that i am aiming for is based loosely on the "gyre" flow design. there will be two vortech pumps at opposite corners to force the flow in a circular direction around the rockwork. one vortech will be at the back left of the tank directly under the wavebox and the other will be at the front right. eventually i intend to add two more vortechs in the remaining corners so that i can switch the flow direction of the entire tank every 20 minutes or so. combined with the wavebox, this should provide adequate flow for the sps corals i intend to keep - at least that is the plan!

here is a link to the gyre flow information: http://www.advancedaquarist.com/2007/1/aafeature

this is my overhead tank design plan showing the aquascaping and flow points. the two small circles are tunze nano streams to provide some additional flow - the return is behind the overflow.

the tank was delivered on friday evening - i accepted delivery after careful inspection. it looks fantastic!

saturday we moved the aquarium to my basement where it is going in-wall with a fish room behind the aquarium. in preparation for the new tank, i thoroughly cleansed about 300 lbs of old liverock by soaking it in muriatic acid and ro/di water to break down the surface of the rock releasing any bound organics. the rock was next soaked in bleach water and then rinsed thoroughly and left out to dry. after the tank was on the stand we began the process of aquascaping. we used a quick-setting hydraulic cement (replacement for thorite) to build the rock column around the overflow. this wednesday we plan to finish up the aquascaping, but for now, here is a teaser!

more pictures to come as the project progresses.

cheers!

Is that what you'd recommend for ALL baserock to make sure it has nothing bad left in it? I have some sitting outside drying out (was planning on leaving it there for a few months), but didn't realize that there might be issues with it.
 
thanks for the compliments.

wardworld - over time liverock absorbs nitrates and phosphates in an aquarium. since this rock is all recycled rock i've used in tanks before i wanted to be sure to cleanse it as much as possible. the low ph from the acid breaks down the surface of the rock - it literally "boils" in the stew and produces a froth of tea-brown foam at the surface of the water. there is a video on youtube here:

whitetip - i have 420 lbs of sand of various brand and grade for this project:

finished the aquascaping tonight. have to say that i love it! behind the rockwork there is a full 5" or more of open space...actually behind the rocks is a whole separate tank - i think i'm going to experiment with a new idea for a background which will allow full viewing of the back side of the tank. i will have to take another picture of the back side...it is very neat in itself. the rock structures on the left and right are almost "false walls" - one layer only of rock...will be good for me to get behind them with a powerhead to blow off weekly. no spots for ditritus to really collect.

edandsandy - different grade sands so that hopefully it won't blow around too much. different brands just because it was available.
 
rinsed the sand and put it in the tank - it is slowly filling with ro/di for a final rinse of the sand.

i put one of the vortechs in the tank where it will be and am getting good flow throughout the tank - albeit just a little over 1/2 full. with two i will definitely have good circular flow. with one in each corner rotating the flow direction every 60 seconds (realized this is the longest you can set the slow pulse), i don't think there will be any possible dead spots even before the wavebox starts rocking the tank.

thank you! :)

today a friend brought over his low-range po4 hanna meter. it looks like all the effort i've gone through to cleanse the rock and sand has paid off! this is still the initial "test fill" and final rinse with ro/di.

po4 = 0.02

rock looks very good...have a shot that shows the depth of the tank? just to get a better spacial idea of the rock?

i like how you have hidden the wave box etc...i would be tempted to put the two tunze nanos on the back glass aimed forward, and have them oscillating back and forth between one and other, every once and a while you will have the wave box blowing the same time the closest nano...i think that would give you really random chaotic flow patterns...as the nano would deflect the water a bit into the pillars..

very nice looking forward to following your build..
 
i really like the flow setup that you are using! I can't wait to see it in action. Where did you get the cement used in your aquascaping?
