i was wondering if anybody knows weather cement (dried and hardened) is toxic in salt water, or could over time release toxins into the water?
i was wanting to try to make artificial caves and things the octo would enjoy checking out, i was going to use cement but then thought of the chemicals involved, although once hardened the chemicals might not release into the water.
