1 I rinsed the new Flourite gravel 4 X's and filled the new tank to 1” with new (rinsed) Flourite Substrate.
2 Placed a 25 gallon plastic tub near the new tank and siphoned 15 gallons of water from main tank into buckets to fill the plastic tub, when just under half the water from the main tank is reached I stopped and place the submersible heater in the tub.
3 I carefully removed all the plants and floated them in the tub
Filled the bucket 1/3 full of old tank water and begin catching the fish. I covered the driftwood with a medium plastic kitchen trash bag
4 I then removed 2/3 of the flourite grave from the 37 and placed it in the 65 and then topped it with 1" of new flouite gravel.
5. I filled the new tank half full of water (33% distilled to 67% tap water) brought to the same ph, temperature and hardness, then added the remaining established tank water. I then place the new submersible Heater in new tank and placed the two filters and ran them for half an hour.
6 Began to landscape with plants and driftwood, terrain going no deeper than 3” and no shallower than 2” in the front, then the rocks, I then allowed the tank settle and clear with the filters running another hour.
7 I Transferred 1/4 of the tub water to the new tank . Compare the temperature and PH of the new tank to that of the tub water. The I began taking a gallon of the new tank water and poured into the tub with the fish then took a gallon from the tub and poured it into the new tank. I continued until the parameters were exactly the same.
8 I then netted all the fish one at a time and placed them into the new tank and transferred the remaining water from the tub to the tank and filled to the top with new water. Placed the light fixtures and turned on one light so I could observe the fish for the next couple hours.
