First you need to know if the lr was enough to start the cycle.(which i assume it was). hows nitrites. nitrates and ammonia????
If it wasn't, you'll need to ghost feed or do the "raw" shrimp thing..
To test the Koralias before u take them back, place them in a bucket of water and then put hand in. Now, reassemble ph's and re-test again..
The results will take u to the next step..
