dKH from LFS

[miketeo3]

I been purchased coral from different LFS and measure their dKH, It is not at reefer recommended value that it is above 8. My reading for LFS is at 6.5 to 7.5 dKH. Is anybody our there try this before and can explain the reason behind?

I'm using Tetra dKH measurement kit.

Thanks.

reason ? they all just use seawater.

hahaha...the LFS here sell fishes and corals by batch. each batch are not supposed to stay long in their tank. It is differ from our tank which we will maintain for years..

So they just use seawater and whatsoever content is not of their prob. U think they will go and measure nitrite, nitrate, ammonia, strontium, Hardness and watsoever like us ?

Nope. as long as there is a rough guide there and the pH is alright then everything is fine.

Maybe only farm is more particular on that. Shops wun really care much. This is the advantage of batch selling.
