    • No white lines on mine

This thing is awesome. It matches the other one perfectly. I would have been fine if it had the white lines as Seiryu stone does but this one has none. They must have changed the design due to all the feedback is my guess. I’m very very happy, I love it.

    • Stagnant water becomes toxic
Style: Type 2
Review Image by Amazon Customer
Toxic to shrimp and caused 15 of my shrimp to die. I took it out of my tank after only a week of it being in there and when I smelled the hole where water gets trapped and is stagnant, it smelled like toxic paint fumes and I knew this is what was causing my shrimp to climb to the top of the tank and try to escape and caused about 15 in total to die. ... show more

Item is fine and I'm going to keep it. However, I'm frustrated that UNS charges so much for a simple mass produced rock mold. It's not "hand crafted" by any means. It's a lightweight, simple molded resin that probably costs pennies on the dollar to produce. The listed dimensions are not entirely accurate so here is what they actually are - 14.75" L x 6.2" H x 7.25" D All in all, it's cool looking if you have the money to spend. Otherwise I'd recommend real rock where you could get at least 10-20lbs for the same price or less than a 2.5lbs mold. I got it for an ADA Paludarium which this rock is suited perfectly for. NOTE: The inside of this is hallow. If you are using it in an aquarium, make sure there are no openings at the bottom that would allow a creature to swim or crawl into the hallow underside or they could become trapped and die. ... show more

    • Really realistic Seiryu Stone for your panted tank.

This is very realistic! The white lines are supposed to be there as can be seen in real Seiryu Stone. Do not believe that 1 star rating!
