When to add LR??!! HELP

Okay sounds good but 5 coctail shrimps sounds a bit overkill, one is good. Just leave it in there untill it's completly gone. All the shrimp is for is to rot which inturn causes ammonia, the first stage in the nitrogen cycle. The rock and sand has bacteria and bugs in in that will decompose the shrimp into ammonia into nitrite, and finally nitrite into nitrate.

Now you play the waiting game untill your tank is cycled and gone through the complete "nitrogen cycle".

If you heard of a DSB (deep sand bed) this is an area which there is special bacteria converting nitrate into nitrogen gas and is removed from the system.

Once your system is full with salt water top-off evaporation with freshwater, preferably RO/DI.

But why am I telling you all this, you should know already, right?
