Ppm=x=per Gallon

how much ammonia do I need to raise a 29g tank 1 ppm?

It depends on the concentration. The best way to figure it is to add ammonia to a 5 gallon (or what ever size you have for water changes) and then do the math. If it takes 10 drops to raise it to 2 ppm then triple it to get to 6 ppm.

This is a partial copy and paste from a reply of mine on a different thread.

Do you know what the concentration of your ammonia solution is? If you do, you can work out roughly how much you need to add.

My bottle is 9.5% ammonia ( but yours may not be, so I wouldn't assume it is ).

9.5% ammonia means there is 95mg of ammonia in 1ml of the solution, which for the sake of ease of calculations, I rounded up in my head to 100mg/ml
So
100mg in 1ml
50mg in 0.5ml
5mg in 0.05ml

As luck ( or rather maths ) would have it ppm of ammonia is the same as mg per litre - eg 5ppm of ammonia in the tank (which is what we want, more or less) is the same as 5mg per 1000ml, or 5mg/litre.

So back to our calculation

For every litre of water in my tank I added 0.05ml of my ammonia solution.

I tested the theory by adding 10x 0.05ml = 0.5ml of my ammonia to a 10litre bucket of water and tested it, and sure enough got near enough 5 ppm of ammonia. The API test chart jumps from 4ppm to 8ppm. The colour I got was slightly darker than 4 but nowhere near as dark as 8, so as far as i can tell it was roughly 5 )
