Lava rock contains trace metals (correct???), it being volcanic or metal making byproduct. Anyone know if it would be safe in a shark filtration system?f

The trace elements would be varied, but I wouldn't be overly concerned, since the concentrations are not likely more than your standard live rock. My greater concern would be that lava rock is typically sharper than rock/coral - but you say filtration, so I imagine your putting it in your waste basket? BTW - check out oceanproaquatics.com - they have 200# of Hawaiian base live rock for $325 SHIPPED! I just bought 400#.
I use lava rocks in my 300 gallon shark tank fillter and it work's great just make sure you rinse them well before you use them or your water will got to crap.
i have used Lava rock with no problems and I also read an article explaining that they absorb nitrates and I can atest to that as my tanks never went over 10-15 ppm (nitrates)
