ADA Green Brighty Neutral K (Recommended for use in areas where tap water has higher pH and KH)

ADA fertilizers

Quality product in elegant packaging. But not cost effective for large aquariums.

Used with myriad of other ADA supplements

It's hard to tell what is doing what, but the dispenser is really nice. If you have a nano tank, I just put a finger next to the pump slide so that it only dispenses half of what it's capable of dispensing.

Thank you , I will be back .
