Question About Rocks

[Lleongko]

Hi All,

I'm starting a tank and managed to find a few aquarium rocks. Are they safe for opae ula? I heard that some may raise ph and leach elements into the water.

Thanks in advance.

Hi Guys,

I looked around and it think there are Seiryu Stones. Below is a description of them.

The famous Seiryu Stone is blueish grey in color with sharp jagged edges. Most of them consist of deep cuts and crevices within the stone itself. Seiryu Stones frequently have calcite veins within their layers, creating a great contrast from its brilliant blueish grey hue to its stripes of white veins.

Seiryu stones will definitely raise your pH and gH depending on how many pounds per gallon you have added into your tank. They are completely shrimp safe for Red Cherry Shrimp, Ghost/Glass Shrimp, and Amano Shimp. When getting into Crystal Red shrimp, it becomes a bit risky and you have to be cautious or counteract your rocks if they are affecting the water parameters too much.

Any thoughts on if its safe for Opae ula? Raising PH seems ok, I only have coral sand in my tank now, what about GH?

Thanks!!!

From what I know as long as they’re not live rocks you’ll be fine. Just make sure you clean them. I usually boil mine first and then let them cool down and rinse off before adding them to the tank.

Hi Lloengko,
I have a .8 gallon jar that I started in March. I have 3 Seiryu rocks in there ( each is about ~4-6”). So far I have had no issues. Since I decided to take a simplistic approach, I never tested the parameters of the water (expect for the salt level when I first set up the tank), so I can’t tell if the ph level is changing. My shimps seem happy and so far no casualties, so I am happy with my rocks.
Good luck and please post pictures when your tank is set up

Hi,

I have already boiled them. But one of them still shows a green colour after cleaning. Not too sure what that is.

Thanks!

Hi,

Good to hear! I will prob be adding the 2 pieces of Seiryu in later. Hope for the best!

Thanks
