Hello. i have a simple question.

I have about 100LBS of rock in my back yard, these rocks have been there for over 6 month and are dry and white no algae or anything on them, I took them out when I redecorated my tank with fake coral and sculptures.
Now I want to put them back into the tank.

If I use these rocks again, can something bad happen to my tank and damage the water levels?

Thanks for your help...

As long as nobody put insecticide on them, they should be ok. They will probably grow algae for a few months, as the phosphate leaks out of them.

yeah I just saw your article the other day on MOFIB. The problem with those big systems is you need a lot of light, I reckon natural light is the way to go for those peeps with larger scale breeding set ups.
