J-Dog Posted March 16, 2012 Share Posted March 16, 2012 What do u guys think is the best way to elevate your live rock, so that it's not buried by sand? Would eggcrate underneath it work, or would it contaminate the water over time? I need some ideas, please help Link to comment Share on other sites More sharing options...
Burningbaal Posted March 16, 2012 Share Posted March 16, 2012 I've seen people make pvc structures that basically sit in the sand and lift the rocks ~1/2-1" off the sb. also, look at oxx's build thread, he used big box structures in the back to give height...

MVPaquatics Posted March 16, 2012 Share Posted March 16, 2012 "big box structures" a.k.a. milk crates. Yes eggcrate will work but will inhibit sandstars, snails, gobys, etc from sifitng. It can also cause dead spots. I like pvc towers more. Just try to keep the part IN the sand to a minimum Link to comment Share on other sites More sharing options...
J-Dog Posted March 16, 2012 Author Share Posted March 16, 2012 I don't want to build any towers or have PVC showing anywhere. I just want to lift the rock so that it is close to my sand line. How would one construct a PVC structure that sits in the sandbed and lifts the base rock? I've never seen that before, so I have no idea what it would look like.

MVPaquatics Posted March 16, 2012 Share Posted March 16, 2012 Use like a few inches of 1.5-2 inch pvc pieces. Like a soda can without a top or bottom. Bury them into the sand. Then cradle the rock on top of them. Spacers basically. If you want to bury something, use the plastic cutting board material (forgot the technical name). I would avoid things with little holes like eggcate. They fill with nastiness Link to comment Share on other sites More sharing options...
Burningbaal Posted March 16, 2012 Share Posted March 16, 2012 use elbows, T's and 1-2" pipe to create a network that will fit under the sand, then upturns wherever a support is actually needed and have a pipe that goes up to right at the sand surface. I'd fill the open end with epoxy or something so you don't gather detritus in the pvc system. Link to comment Share on other sites More sharing options...
Smann Posted March 17, 2012 Share Posted March 17, 2012 How about drill the rock and insert some acrylic rods, cut and level. Not sure why you need to elevate, I cut my rock bottoms flat on a tile saw then puttied them in place building the structures as I went then filled in the sand around them. Some pieces only had small points of attachment to the bottom where they were cut Link to comment Share on other sites More sharing options...

I was thinking that if I had a deep sand bed, I didn't want half of my base rock buried underneath. Cutting some pieces flat might be a good way to have something underneath Link to comment Share on other sites More sharing options...
Smann Posted March 17, 2012 Share Posted March 17, 2012 I did a shallow sand around the outside perimeter of the rock work then deeper in the rock areas. I have a few Tigertails that move a lot of sand around from the outside area to the inside and back Link to comment Share on other sites More sharing options...
