Test kit brand comparison

Browsing on ebay. Found these brands that have some good master kits. With my students, the more different tests - the better to keep them occupied. I also want kits that require mixing in test tubes/well trays - not simple test strips. I need the kit with the MOST tests as well.

Of course, price is always a consideration since this is out of pocket - but hopefully reimbursed.

Instant Ocean - Reef Master test kit - has 5 parameters. seems to average around $65

Nutrafin Master test kit - has 10 parameters. Seems to average around $85

Hagen - Aquarium master test kit - 10 parameters. Around $100

API Master freshwater kit - 7 parameters. Around $30

The students will be comparing two different freshwater habitats - African rift lake vs Barb stream.

The API is good, I use the tetra laborette.

i would go with API. i just got one and they are super easy to use.

o yeah and a FYI i paid $18 for mine at a online whole seller like www.bigalsonline.com

I've used the API chemical master test kit for a while. Works for me...

Is the API Master Kit just simple strips you dip in the tank - or do you use a dropper with indicator and then check against a color card?
