I think it was Jim Perry who had mentioned that it wasn't good to use abs. But hey! It's worked in John's tanks for years. Mabe it was that whole not suitable for drinking water thing that I had heard.]]> Mon, 21 Apr 2003 21:53:19 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2702&title=raising-rock#2702 <![CDATA[raising rock : ABS pipe is absolutely safe in...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2690&title=raising-rock#2690 Author: Mark Peterson

ABS pipe is absolutely safe in an aquarium. Yes, absolutely.

A question is whether one wants black or white pipe showing in their tank. Black is less noticable and coralline algae grows on it just as well as white PVC.

But do they manufacture 3/4" diameter ABS?

It really doesnt cost anymore to use the pvc so I think I will stick with that. However I wouldnt think that there would be a problem with the abs. Just better safe then sorry.]]> Mon, 21 Apr 2003 10:45:56 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2688&title=raising-rock#2688 <![CDATA[raising rock : Quote: Originally posted by sjlopez39...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2684&title=raising-rock#2684 Author: jfinch

I don't think that's true. I've used abs on almost all my tanks without any problem. I think some people get spooked by it because it's not nsf-pw (drinking water grade).]]> Mon, 21 Apr 2003 09:28:01 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2684&title=raising-rock#2684 <![CDATA[raising rock : I think raising the rock is beneficial...]]> http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2681&title=raising-rock#2681 Author: sjlopez39

I think raising the rock is beneficial in a few ways. It allows less rock having to be placed directly on the sand bed, therefore helping to maximize the filtration going on there. As earlier stated it allows fish to feel like they are hiding while they still are more easily seen. It can also allow water to be circulated in areas that may not normally get circulation if the rock is blocking the flow.

The material I used for my shelf is 1/2 inch pvc with holes drilled in it. I basically copied the one that was at Bird World about a year ago.

My reef structure is built on two PVC steps. The bottom level of rock is on the base of the tank in the sand. The rock then stacks up from here on up the steps, completely hiding the PVC structure. This creates a full looking tank but provides a lot of room for fish to swim and hide.

I agrea with what Suzy said part of the reason I want to do this is to provide extra hiding places for fish and inverts. Also I plan on having some rocks sit on the sand bed in front of the pvc legs to hide them. I dont think it would hurt to have a few on the sand bed.]]> Sun, 20 Apr 2003 10:17:57 +0000 http://www.utahreefs.com/forum/forum_posts.asp?TID=427&PID=2673&title=raising-rock#2673 <![CDATA[raising rock : Hi, Mark.

Hi, Mark. We used an eggcrate/pvc table just because I didn't want to buy a ton of rock! Our structure is hollow, with plenty of room for fish to hide and sleep at night. I think if fish have places to feel "secure" ,they are less skiddish and actually hide less...BTW, who is our fish psycologist?

If you place your rock the way Jon Finch described in a post about a week ago, you will be fine and will avoid having the artificial grid visible in your tank.

Place bottom rock on edge rather than flat. Push it down through the sand until it contacts bottom, so that burrowing fish, shrimp or crabs cannot cause it to topple.

After hearing the warnings and seeing this method in use for many years in many tanks, it seems to me that the worry about keeping all rock off the bottom is overkill.

I would like to hear differing opinions.
