Hi I Recently Upgraded My Tank To A 120l From A Previous 70l Tank

Hi Amlaikin 

Using some of your existing tank contents, particularly the filter (as long as it wasn't left out of water for any length of time) should help - I used a similar method when I set my tank up last year and found that it cycled very quickly. However I was doing daily tests using the API Master test kit to check the state of play.

You would need to test yours to be sure - do you have a test kit? If not, I think most people on here would strongly recommend that you invest in one (liquid tests, not strips) - buying off the internet is probably your best bet as they can be around half the price of the ones in the shops. They can seem a bit expensive but they're not just useful during the cycling process - it's good to carry out routine testing and they can sometimes help find the cause any problems you may have with your tank water at a later date and therby enable you to take corrective action quickly.

Hi. Thanks for the quick replies!
Yes I have the API test kit but haven't been testing every day do will change that! The old filter didn't dry out and I intend to leave it in there for a good while. Also planning weekly 30l changes. Good to know I'm on the right track. Thanks 

Well the tank (Fishpod 120) came with a filter but it's quite noisy. My old filter - a fluval U2 - is not big enough for the new tank i think so for the time being I'm using both until I can maybe afford a U3 which I think would be ok on its own (and hopefully as quiet as the U2!)

Great advice, thanks Sue.  I had not thought of that but will do it
