Rock before sand. Why?

[GotSalt?]

i know a lot of people say add rock then sand later and i was just wondering y you did this . when i add the dasd i would assume that i would turn my filters and PH's off am i right

The main reason, is because of rock slides. If the rock goes in first, then the sand won't shift under it, causing rock slides.

 

In my opinion it really isn't a big deal to put in sand first. That is what I did. I filled the tank with water. Then poured my sand in. Then after a couple days I put my rocks in.

 

I have yet to have and rock slides. And if you think about it, your probbably going to rescape at some period anyways.

am i right about turning filters/ skimmers and power heads off whe the sand goes in

[dyceskynes]

Its a good idea, you would not really need them running. With the power heads off the water will clear faster. I kept my ac500 running and put a filter in to help clear the water.

First sand, then rock, because otherwise the sand won't creep under the rock.

I usually add the tank first. lol

 

I added my sand then my rock But I pushed the rock into the sand so as to avoid any rock slides

i add the sand and wait one week for the sand to setle in

and then i put the rock in but thats just what i do [aB]
