Sorry I do not have any pictures to send. But really it is fairly simple. You can get the
PVC from
HD or any other HW store. Just look for a short section of 2" gray Sch. 80
PVC. This is very common and used by electricians running mains and feeder circuits. If you are going to use a 4" base, just use a hacksaw and cut 4" lengths of the
PVC. Based on your aquascaping, use enough legs to fully and stably support your rocks. Use a marine epoxy to glue these onto the base rock when you are happy with your dry run setups (sort of like setting up a model
Now, as far as setting up the
LR, this is where your personal taste comes into play, you may want a reef wall setup or an atoll set up with a lagoon in the middle. Get some reference books and you should see some ideas there, or look at some of the set ups from the members here for ideas too. Build the structure so that it is sound but not compact, leave lots of little holes and spaces for water circulation. Again, use marine epoxy to cement together once you are satisfied. Remember do not place it all the way against the back glass, leave room for circulation. The idea here is to avoid any "dead" areas in the tank. Once you have built the Base Rock, build it in mind of placing the additional
LR on top. The beauty of using the Base Rock is that you can work dry and even outside the tank using a template of your tank shape, before you ever put it into the tank
Once the design is complete then you will need to add the sand base (nothing live yet until you have conditioned
SW). Then its adding the water, bringing it to temp and adjusting the salinity. Note that you should not fill the tank all the way to the top as you will have displacement of water when you add the
LR. Final step is to add the
LR and if you feel comfortable with the stability, leaving it to sit on the Base Rock, or whip out that old marine epoxy which will work underwater. Maker sure you are keeping the
LR in the water to prevent any die-offs (though unlikely in a short time). Again, if you want a good reference book see the recommended list in this forum. Hope this all makes sense and helps. 8)
