To do a fishless cycle.
- Set up your tank, filter, heater, lighting etc. I would probably fill the tank, get everything running for 24 hours to make sure it all works before going any further. Drain it down, aquascape in a dry tank, refill, add water conditioner. If you have access to established filter media then add it into your filter or if its an old sponge squeeze the sponge into the water. Raise your water temperature to around 29c/85f.
- Dose ammonia up to 4ppm. Check with your test kit, dont just rely on any instructions on the bottle. If you are dosing bleach you will need to calculate the dosage based on the amount of water in the tank and concentration of bleach. If doing fish food as much as you would feed in 1 day is typical. You might need to do this daily to get your ammonia up.
- Add any biological booster products as per the instructions on the bottle. This may be some additional doses over the next few days as well.
- Start testing daily for ammonia. Once you start to see ammonia dropping start to test for nitrite and nitrate also. You should start to see nitrite when the ammonia drops and you might also start to see nitrate as well.
- Once ammonia has dropped below 1ppm redose it back to 2ppm. Timeline for this might be 1 to 2 weeks.
- Keep testing daily, every time ammonia drops below 1ppm redose back to 2ppm. After another couple of weeks this should be daily. You will probably be seeing nitrite rising steadily here also.
- After some while your nitrite will also start to drop as this is processed into nitrate. This will likely take another 2 or 3 weeks.
- Eventually you will be able to dose 2ppm ammonia and after 24 hours see 0ppm ammonia and nitrite and nitrate will be rising. You are cycled. Maybe keep it for another couple of days to make sure, do a big water change (don't forget water conditioner whenever you do a water change) to bring nitrate down to around 10ppm. Lower your water temperature to whatever your fish require.
- Go get your fish. Acclimate before adding.
Good luck. Keep us informed on progress.
