Cycle Tank ?

[snowflake311]

It took my tank 7 weeks. It would have been sooner if I did not mess it up. But it's done now. I'm adding fish slowly. First 2 go in tomarow.

One thing to bear in mind when doing the fishless cycle - you are using either a product from the LFS to seed your tank/filter with bacteria or MUCH BETTER STILL you are using a squeeze from an already cycled filter and adding ammonia to 50ppm in a controlled way.
Once complete - and if done properly your cycle will be completed in as little as 10 days - and your ammonia / Nitrite levels are down to zero after each dosing with 50ppm ammonia in 24h - You are ready to add a FULL bio-load of fish in one go - if however you introduce fish slowly, the bacteria that have already built up and colonised your filter sponges/ceramics etc will actually die back to a level where it will support the waste from only the few fish you have put in - you have spent all this time building up hugh colonies of bacteria for a full tank of fish then just adding a couple ..... erm..!!! Ok there is nothing wrong with this especially if your pocket wont permit you going out and buying 20 or so fish at once but it is worth noting that you can add a full tank of fish. Once you add small quantities of fish, im afraid you will only be able to add similar quantities at any one time going forward because you will not have the bacteria built up to support larger numbers of fish.

Hope this helps.
