General reminder: if your test kit is almost expired...

[disaster999]

dont cheap out and go get a new one.

 

i have a salifer mg test kit that is going to expire at the end of the month. i thought it was still good...and because its almost finished so i kept using it. my local reef forum has a special on mg test kits so i bought one today. tested my water with the new test kit and there is 200ppm difference.

 

needless to say im not going to use the old kit anymore.

 

so remember, if your test kits is almost expired, or its reading a lot lower than expected, dont cheap out and get a new one. you rather spend $20-30 on a test kit than losing few hundred dollars worth in coral

Thank you for the tip! I'll certainly keep it in mind.

 

I just purchased the API Saltwater Master Test Kit. I assume it is a decent kit. Am I wrong in assuming?

No. Besides, soon you won't need to test for ammonia or nitrites once the cycle is over.

How long are these good for? I don't see the expiration on my API. It is over a year old.

[disaster999]

theres usually an expiry date on them. just have to look closer. usually its on the bottle itself

Each reagent bottle has a Lot # printedon the bottle.

 

The last four digits are the month and year of manufacture.

Example: Lot # 28A0102. This is a pH reagent manufactured in January of 2002.

 

Pond Care Wide Range pH, ammonia, High Range pH,

Nitrate, phosphate, Copper, calcium and GH all last for three years.

nitrite and KH will last for four years. Freshwater pH(low range) and

Pond Care Salt Level will last for five years. I would not trust these

kits after they have expired.
