Nitrogen cycle #1
Hello :)

After some years away, I have acquired a Fluval Roma 125 to keep a few fish.

I’m pretty sure I can get a filter media squeeze form the person I got the tank from as they were upgrading to a larger tank.

I’m not sure however, that once I start the fishless cycle, using Dr Tims Ammonium Chloride, what is the best time during the cycle to introduce the bacteria from a mature filter squeeze?

Also, the last time I did a fishless cycle, I used prawns inside a pair of tights suspended in the water. But it seems that bottled ammonia is used now to better control the cycle. And also adding fish food partway through the beginning of the cycle.
Is there any alternative to Dr Tims in the UK? Or is that the best bet?

Many thanks
Louise :)

Re: Nitrogen cycle #2
Put the filter squeeze in just before the first dose of ammonia; squeeze it over your filter media.

You can use Dr Tim's, or ordinary household ammonia (with no perfumes or additives). There's an ammonia calculator on this page: https://www.fishkeeping.co.uk/articles ... hless-cycling-article.htm
