Recovered the cpvc frame from the old tank and modified it a bit. It will be stacked agaist the back foam wall for supporting the big rock. I zip tied the rock to the frame which adds more support then leaning the rock against the wall.
I started off with the frame in front of the rear left CLC LocLine, but after seeing the big rock stick too far out, I moved it back to the other side of the Locline.
Side View
LocLine return line coming out of foamed overflow. This is 6ââ"šÂ¬Ã‚ below the overflow teeth. It will not drain down this far, because the loop built insode the overflow. See previous pics earlier in the thread for those details. This works very well, and prevented me from inserting the LocLine one-way check valves, which I thought would likely reduce the output flow too.
Everyone has there own strategy for aquascaping and assembly of the tank. I have done it both ways in the past, and prefer the dry method in lieu of the wet method. The wet method means you put the water in first, then the rock and sand.
I will describe the dry method with the next series of shots. The major advantages to this method is ease of placing sand and rock without constantly getting your hands wet. It is also easier to use cement and zip ties during the dry method. The last major advantage is that the water will be less cloudy since you are not dumping sand into a filled tank. This can take days to clear.
STEP ONE: Add 1ââ"šÂ¬Ã‚ to 1.5ââ"šÂ¬Ã‚ base layer of sand ( Iused Pacific sand here to extend the expensive white sand). Notice its yellow color vs the white color of Bahama sand.
STEP TWO: You should have a general plan for your aquascape design. Next, Place base rock into the bottom layer of sand and press it until it meets firmly with the glass. The base rock will be completely covered (in most cases) by sand. So, this is the place to use dry rock. I used a bit of live rock and some dry rock too. The dry rock is not cheap rock, but the good calcium carbonate reef rock. In other words, it too will add to the buffering capacity of the tank.
STEP THREE: Add all of the sand. It should be rinsed with fresh water first. This is the time to create any wavy areas if you desire. I have a 7ââ"šÂ¬Ã‚ layer on the left which dips to 4ââ"šÂ¬Ã‚ at center and back up to 6ââ"šÂ¬Ã‚ at the right. The sand layer also varies from 7ââ"šÂ¬Ã‚ in back to 4ââ"šÂ¬Ã‚ in the front. Add live sand to the top at this time to seed the bed.
STEP FOUR: Add a small amount of saltwater to the sand bed to keep it wet. Then begin adding Live Rock to create your aquascape design. Many materials can be used at this phase for securing rock. I chose to use zip ties to anchor the big rock to the cpvc frame. I then used Thorite Rapid Vertical Cement to cover the zip ties and to attach rocks to each other. This cement must be kept wet to cure, but working time is over an hour and it is totally awesome!!! This cement is exclusively used at the Wikiki aquarium in Hawaii, and I got the idea of using it from ââ"šÂ¬Ã…"œThe Reef Aquarium Vol 3.ââ"šÂ¬Ã‚Â
STEP FIVE: Once I place rocks in a position I liked, I used the Thorite to fix them in place. Next, I pressed a spoonful of medium sized aragonite sand into the sand to breakup the grey color and to make it look a bit more reef like. In either case, coralline algae will cover this stuff in time.
A picture of Thorite cement and in the red cup is some aragonite sand. I mixed 3tbs water to 1 cup Thorite cement. This project only used about 2.5 pounds of Thorite. I was generous with the stuff too. After the cement cured, no rocks wiggled at all! The stucture is solid.
