Are there any types of rocks one should avoid using in a FW setup due to them affecting water parameters?
My parents are coming to town and they have a ranch loaded with lava rock. My parent's place is about 20 miles as the crow flies to the peak of Mt. Shasta. I spent my younger years stacking lava rocks in piles along the fence lines. I thought the rocks might look cool and give plenty of nooks and crannies for Oto's to keep clean.
Thanks.
