So its safe to say I can break it up into small pieces and leave it in my tank indefinately.

Dont break into small pcs. Just cut into half ir 1/3 if too big.
In small pcs much faster disintegrate and may pollute the tank.

Use Diamond water with mineral rock and mineral balls

i tested my tank ph = 8.2
help??

I was thinking of small pieces to stuff into crevices around the driftwood since the shrimplets like to hide there. No go I suppose.

use full RO water or use aquarium soil to buffer and bring down the ph.

I found out that someone is selling the Hawaiian Red Shrimp (Opae Ula) at Singapore. Below is the website. I email the owner. He told me that he doesn't deliver to Malaysia. It looks like I'll be going to Singapore to buy them when I go to Johor to attend some events in the future.

he won't post cos both sender and receiver need a permit to send livestock across country.
Don't let kastam saw your live shrimp , they will confiscate and issue you a summon on Malaysia side.
