Hello all,
This will, I hope, be a journal for a successful tank cycle by a newbie. You can expect to see some really stupid mistakes (already made a few clangers) and maybe some unique insights into the process (I doubt that
). It will be something of a brain dump, hopefully this will help other newbies learn from the mistakes I have already made and those I am yet to make.
So, here we go...
Initial Kit
Day 1 - Friday - 19th October 2012
Bought the tank today, first setup carried out in the evening:
Day 2 - Saturday - 20th October 2012
This day will forever be known as don't trust your LFS day.
Day 3 - Sunday - 21st October 2012
This morning we woke to milky water (it had been crystal clear until now) - Looks like a bacterial bloom
Day 4 - Monday - 22nd October 2012
Things I need to do
Lesson Learned so Far

So, here we go...
Initial Kit
- Tank Dimensions : W60cm x D32cm x H37cm
- Tank Capacity : 64 litre / 14 impG
- Interpret Delta Therm Heater : 150 watt
- Interpret PF 1 Filter (This was replaced on day 3 - Replaced with a Fluval U2)
Day 1 - Friday - 19th October 2012
Bought the tank today, first setup carried out in the evening:
- Added 1 inch of black gravel substrate sloped down from back to front (so particles roll to the front of the tank)
- Added 62 litres of Interpret Tapsafe treated water
- Set the filter running
- Heater set to 24°C / 75°F
- Added, per instructions, 2ml of Filter Start to the water
Day 2 - Saturday - 20th October 2012
This day will forever be known as don't trust your LFS day.
- On advice from LFS added 6 bunches of live plants. I am still to determine what they are.
- On advice from the LFS 2 goldfish were added to the tank as "this will help you cycle the tank" - Fed the fish
- As there are live plants in the tank now the white light will be on for 10 hours per day (need to keep an eye on Algea now)
Day 3 - Sunday - 21st October 2012
This morning we woke to milky water (it had been crystal clear until now) - Looks like a bacterial bloom
- Fed the fish
- Replaced the filter as the Venturi was faulty - I wanted to run the Venturi to increase water oxygenation and therefore help bacteria growth. Venturi is now running
- In the evening the Goldfish were removed from the tank - adding these was really bad advice and I have learnt the hard way to get a 3rd opinion on these matters. Fortunately I found a good home for them.
- To help with bacteria growth tank temperature increased to 28°C / 82°F
Day 4 - Monday - 22nd October 2012
- Did the first water change, replaced 20 litres (33%) of the tank
- Bought a Tetra 6 in 1 test, results (after the water change) are:
- Chlorine (CL2) - 0
- NO3 (Nitrate) - 10mg/l
- NO2 (Nitrite) - 0mg/l
- GH - 16°D
- KH - 3°D
- pH - 7.2
- Chlorine (CL2) - < 0.8
- NO3 (Nitrate) - 10mg/l
- NO2 (Nitrite) - 0mg/l
- GH - 16°D
- KH - 6°D
- pH - 7.2
- Added fish food to tank to rot out to Ammonia
- Redosed the filter with 4ml of FilterStart
Things I need to do
- Replace the Tetra 6 in 1 test with an API Master Test Kit - it is what everybody recommends and is far far far more cost effective.
- Buy some Ammonia so I can dose the tank to check the NH4 => NO2 => NO3 conversion rates.
- Identify the plants in the tank
Lesson Learned so Far
- Adding filter start into the water is pointless (as I did on day 1), this is better squirted directly into the filters it is where you need the filter start bacteria to be.
- Should really have done more research first - with heinsight I would have bought a larger tank. Smaller tanks are harder to work with as the chemical / temperature fluctuations are rapid and dramatic.
- When making water changes especially big ones make sure the new water is a similar temperature to the tank - My first change saw a dropped from 28°C to 18°C - Fortunately no fish in the tank at this point.
- The Tetra 6 in 1 test doesn't test for Ammonia so you don't get the full picture - its is also a strip test which I don't have an issue with but most recommend the API Master Test Kit
- The tank can only be considered good to go when it can convert 5PPM of NH4 (Ammonia) into NO3 in 12 hours

You might want to post this question as a new topic. I'm sure one of the really knowledgeable people on this site will come along and help you. Good luck! This whole fish keeping business is more complicated than it looks, isn't it?
That said one of the LFSs did a free water test (with an API kit) and the ammonia level was at 5ppm. This was added on day 5 and it would seem that none of it has been processed, which leads me to the conclusion that there is no/little bacteria in the filter.
