Aquascaping LR, to PVC or not to PVC that is the question.

Tinpusher,

Just thought of how I cure new LR. Instead of curing it in my display tank, I cure it in a separate container with heater, lots of water flow and some light. That way, I don't get all the crud that comes off the rock in the display tank which results in algae/cyano problems sooner or later. Also, I change some of the water every so often and swish each rock in the outgoing changewater to remove even more crud. You'd be surprised at how much dead stuff comes off the rock during curing. Not stuff I want in my display tank, especially if I had sandbeds to catch it all.
