Ammonia Dosage Question.

Hi, am I right in thinking that 3ppm of ammonia in a 190l tank will be about 9ml?

I worked it out using the following method, 0.016060=1ppm so 190 x 0.010606 =3.0514, I need 3ppm so 3 x 3.0514= 9.15ml

Does that sound about right, I got the 0.01606 figure on this forum somewhere I think and took a note of it but forgot exactly where I found it.

Edit - I think the figure was originally worked out with 9.5% ammonia

40ppm is a little on the high side no? I thought it was 3ppm

From Sue's method,

1. Calculate your dose of ammonia. This would typically be 0.3ml for every 10 litres of tank water; but because bottles of ammonia vary in concentration, it is better to dose at 0.2ml ammonia per 10 litres, then test after 30 minutes (to allow the ammonia to mix in). If the result is lower than 3.0ppm, add more to get to that reading. Make a note of the total amount of ammonia you add - See more at: http://www.thinkfish.co.uk/forum/index.php/topic,483.0.html#sthash.jKZgNHjC.dpuf

I'm now confused 

Thanks Sue, that's cleared it up.

Just awaiting a heater and I can get going 

There has been a lot of new knowledge published in the last few years.
The ammonia eating bacteria that we want to grow are inhibited by high levels of ammonia, and a different species grows. The critical value is 8ppm. So the ammonia level must not exceed this level if we want the correct species.
Nitrite eaters are inhibited by levels above 15ppm, but our test kits can't measure that high. Since 1ppm ammonia is converted to approx 2.5ppm nitrite, it only takes the addition of 6ppm ammonia before the nitrite eaters start to grow for them to be inhibited.

A new method of fishless cycling was devised last year, and I have written this method up on here. It aims to keep ammonia below 8ppm, and the resulting nitrite below 15ppm until both bacteria species grow enough to deal with more.
This method also relies on the discovery that the filter bacteria don't starve to death in 24 hours as used to be thought. it is now known that they can go a lot longer without food, so ammonia doesn't need to be dosed every day.
