I just used 5 gallon buckets and moved the Rick out with the crabs and snails. Then another for the fish. With the tank water obviously. Then scooped the sand into bags. Siphoned the rest of the water from the 36 into the 50. Then I put the bags of sand on the bottom under water and cut them open to minimize the clouding of the water. Added the lr
. Waited about an hour for the water to clear. Then ran the filter system for about twent minutes. The fish spent two hours in a 5 gal
bucket with a hob
filter and an air stone. Once the tank water was clear I added the fish.
