What I do to cure LR.
(a)Firstly, I soak all LR in fresh water for at least half an hour.
(b)Then I clean all the LR by using a brush to it clean.
(To clear unwanted stuff e.g. Sponge and worms etc.)
©After that, I place all the LR in a blue tub and use a skimmer and DIY filter
and run for at least two to three weeks with sea water. In between, I change
water and add calcium and other stuff.
To be very frank, this take alot effort. But the cure LR look goods and smell
fresh.
