I have a deep aquarium (36") and have been looking at some long reach tongs. The ones I see for aquarium use don't have the best reviews. I was looking at the grabber tongs on Amazon that have pretty good reviews and can handle a little weight but are made from aluminum, I know aluminum has some negative effects in a reef tank but for moving corals or small rocks I figure the contact time with water negligible. Wanted to get others thoughts and feedback before I make a purchase. TIA
