So far so good. Has been in my tank for about a week and everyone is still happy. Thank you!
These last quite some time in my tanks, they do not break down and dissolve quickly like all other calcium chips I have bought else where. The price is fantastic too, cheaper than amazon too! Thanks!
It's a great product I think they will help the water quality of my tanks how ever they only lasted like a week it said they would last a month hopefully once I build up the minerals in the water from wonder shells I'll get a longer life span out of them
