are they copper free?

yes. no copper. api has a phone number you can call for more info. i have found them very helpful when i had questions.

My tank is 30 gl I need use how many tablets?

The instructions say you should use 1 tablet for every 30 square inches of gravel surface area. Most 29 gallons are 30" x 12", which is a total of 360 square inches. Divide that by the recommended 30 square inches per tablet and you will need to use 12 tablets for the aquarium, once per month. Of course, that's providing your aquarium is 30" x 12".

i have a 20 gallon tank, can i use theese with the liquid c02 booster and leaf zone or flourish excel?? or will i be adding to much.

I use them with leaf zone and flourish Excel... no problem so far...I do not treat the whole tank with this tabs... I only add them to specific plants that need more nutrients such as my aponogetons ( bulbs)

I need use how many tablets for 30 gl?

I put all 10 inside a 60 gal. I guess just put 5 for the 30 gal.
