Has anyone tried notching thier egg crates?

[sikpupy]

I want ot put my rock on egg crates but I am a little apprehensive about it. I dont want to have an area of stagnated sand, but, then again, if I put my flat bottomed homemade rock right on the glass, am I not just doing the same thing?

This got me to thinking (imagine that) again..... If I got some egg crate, pulled my circuler saw blade up to about 1/4 depth and channelled the heck out of the egg crate squares, placed the chanelled part on the bottom glass, I would have some flow under there!

Has anyone tried that and lived to tell about it with all apendeges intact?

Egg crate is very brittle and will get even more so in water. I use some as a guard on my aquafuge. After a while in SW it gets very brittle.

So one day I imagine you would have a rock collapse.

Most people make rock stands out of PVC pipe. Why not try that?

Also, I've read that some eggcrates are made of styrene and release chemicals in the water which fuel unwanted algae. People look for the eggcrate that is made out of acrylic. Don't know if this is true, but I did noticed that the eggcrate I used as a frag rack had a lot of hair algae on it. Also, I had a bryopsis outbreak soon after the eggcrate addition.

You serious about that ????
I have some egg crate on top of some plastic plastic pipe so that I can get my rock work higher to my T5 lights .... so you are saying that eventually this egg grate will just break in the water ? over what time period ? months, years ??

Hmm, never thought about the brittleness of it, but, I would assume if sand was filled into the little squares, the rock should not go anywhere. It will be homemade rock and pretty flat too on its bottom.

As far as the chemicles go...............

Two things: acrylic egg crate is better than PS egg crate AND egg crate will become brittle

How brittle would brittle be-come? there is brittle to a point if you dont move it, it will be fine and then there is disintigrating brittle. Along with some sand in the litle squares, should still be a sturdy brittle floor support system, I would think.

Still, has anyone tried notching?

Brittle to the point of smashing every joint along the cut line.

"I dont want to have an area of stagnated sand".

I used eggcrate on the bottom of my tank mostly to protect the glass.I good many reefers do,not sure why you're concerned about stagnated sand.

Hummm..its been used for years and years, by thousands and never heard of a single problem. Starting another reefers fable?
