I have found the least expensive ammonia is usually pure/no additives.

Quote>>It doesn't list ingredients, but it's the cheap stuff so I'm assuming they haven't added anything to it...I haven't shaken it yet, but I'll do that when I get home<<

Good thinking.

Addatives added / will be listed.

Just like cholrine/bleach... the purest is the cheapest. no addatives.

Keep us updated. ok.

Well it turns out I don't have generic ammonia I have Goldex. I did a google search & found out it's 5% ammonia, 95% water.

My next question is this: all the fishless cycle articles talk about ammonia readings in ppm, but my test kit only gives mg/L. Does anyone know how to covert this? or what readings I am looking for in mg/L?

mg/l = milligrams per liter is the same as ppm = parts per million.

The nice thing about metrics.

\eg: cc = cubic centimeters = 1 gram

1 liter water = 1 kilogram / 2.2 ponds.

The ammonia _ Goldex - the good stuff. 5% ammonia is as good as it gets for the general public use.

You want to add the ammonia to the tank water until you get a reading of 5ppm, on the test kit.. This will kick start the cycle. Ammonia is food for the bacteria[1st].

A nitite test kit will start to register in a couple of days.

Nitrites - food for the 2nd bacteria.

Same measurement.

EX: the difference between 36 inches and one yard :smokey:

One Liter = 1000 grams or [cc].

1 Mili = 1000th of a gram or [cm]

1000 x 1000 = 1,000,000. = part per million

METRIC = everything is based on units of 10.

Hope my math is correct.

Taken from the pinned article on the fishless cycle:

"then add that amount daily until the nitrite spikes. Once the nitrite is visible, cut back the daily dose of ammonia to ½ the original volume"

So, do I cut back as soon as I notice nitrate, or when it spikes? What is considered a spike?

Also,

what I'm not getting about the ppm = mg/L is that some "parts" would weigh more that others, wouldn't they? I.e. does a part of ammonia weigh the same as a part of nitrite? Does this have to do with the difference b/w weight and mass?

John: Yes, as soon as your NO2 test kit starts to regIster - cut back on the amount of NH3.... you have been adding to the tank -- to 1/2.

The Nitrites: are a sign that the first bacteria are becoming established. ThIS bacteria will continue to grow and multiply, excellant!! :wub:

This bacteria "EAT" ammonia. This is their food! ... Nitrites are their waste. ( can you say ""poop")

Nitrites; the waste product of the first bacteria ... will continue to increase; as long as there is a food souce. [a.k.a NH3's].

BTW -- NITRITES ARE VERY TOXIC! More so than NH3's.!! :tongue:

After a point in time you / your test kit will register a decline in the NO2's.

This is because the second bacteria have started to "develop"..

Their "FOOD" is NO2's; the waste product of the first bacteris:wub: :wub: [A.K.A. NITRITES ]

A NITRATRE test kit wil tell you this..... NO3's...... will start to register. :o

This is a sign that both bacteria have colonized, established themself, and started to reproduce.[multipy]. :o

The "second bacteria" are the ones that consume NITRITES... YUM YUM :smokey: :smokey: > like a child in a candy store...

Here is a post from a thread on the aquatic plants digest on units.

http://fins.actwin.com/aquatic-plants/mont...5/msg00042.html

The Amazing Metric System

<http://ts.nist.gov/ts/htdocs/200/202/mpo_home.htm>

CGS = centimeter-gram-second system

Volume

“L” is the abbreviation for “Liter” which is also 1000 cubic centimeters

which is written as cm^3 (never use cc!)

“mL” = milli-Liter = 1/1000 of a liter = 1 cm^3

Length

“m” = meter

“cm” = centi-meter = 1/100 m

Mass

“g” = gram

“mg” = milli-gram = 1/1000 of a gram

1000 g = 1 kg = 1 kilo-gram

Time

”s” = second

Density of water is 1 g/cm^3

1 Liter of water = 1,000 cm^3 of water = 1,000 g of water = 1 kg of water

1 m^3 of water = 100 x 100 x 100 cm^3 = 1,000,000 cm^3

= 1,000 kg = 1 tonne (metric ton)

1 mg of substance dissolved in 1 Liter of water =

= 1 mg/L =

= 1 mg substance in 1,000 g water =

= 1/1,000 g substance in 1,000 g water =

= 1 part substance in 1,000 x 1,000 parts water

= 1 part per million (ppm)

Quiz:

1) 1 g of Potassium in 200 L of water gives you how many mg/L of Potassium?

A: 1000 mg/200 L = 5 mg/L = 5 ppm

2) 1/4 tsp. of Potassium in 55 gallons of water gives you how many ppm of

Potassium?

A: I have no idea.

3) How much Potassium Sulfate does your 55 Gallon plant tank need?

A: A big pinch every couple of days. Try more or less and see what

happens.

(and let’s not get into how much K is in 1 g of K2SO4!)
