Water conditioner use during fishless nitrogen cycle

I used seachem prime when I added water first time in my new tank. Do I need to keep adding it every 48 hrs(2 days) or only during partial water change after nitrate formation?

Hi umangkej, welcome to the forum!

As a water conditioner, SeaChem Prime only needs to be added during partial water change. If there is an ammonia spike when you already have fish in the aquarium, then partial water change with Prime every other day is a solution to minimize the ammonia damage to the fish.

By the way, do you have fish in your aquarium? Or are you trying to do fishless cycling?
If it is the latter, you need a source of ammonia to get the aquarium nitrogen cycle started. In this case, you do not even need partial water change at all until the nitrate concentration is too high.

Thanks thor.

The ammonia solution I saw in a local laboratory chemical shop has a label with following data only

Pure Ammonia
Specific Gravity - 0.91.
Assay 25% min.
Maximum limits of impurities: 
non volatile mater - 0.01%
Chloride - 0.001%
Sulphate - 0.002%
Arsenic - 0.00002%
Iron - 0.0001%
Lead - 0.0001%


Can I use it for fishless cycling?

I have already started nitrogen cycling with fish food but haven't got any traces of ammonia when I tested with API freshwater master test kit.

Please suggest if I can use the above mentioned ammonia solution for cycling.

Thankd

Probably not.
I am not a chemist though. Is it the full list of ingredient?

Ace Hardware carries a product made of 10% ammonium hydroxide plus 90% water with nothing else in it. I used their product for my fishless cycling.

There is one ammonia product made specifically for fishless cycling. It is called Dr. Tim's Ammonia Chloride if I remembered it right.
