SunGrow Snail and Crayfish Energy Balls, Enhance Color, Calcium-Rich Gray Pearls for Invertebrates, Functional and Beneficial Aquarium Decor, 10-Pieces per Pack

Drop and go! I put one each in my tanks with my triops, they will occasionally go nibble on them while skimming the floor is the tanks. So far so good, happy with my purchase

Value for money

It works! I soaked in old tank water for 8 hours before putting in my 10 gallon, and tested the water.. raised the PH a lot but not the hardness, which I was looking for. Since putting them in the tank I haven't seen much difference, as the tank is bigger than the small cup I tested them in. Hopefully will raise PH and give my cherry shrimps some minerals to help their colors and molts. They sort of ignore them, similar to my other decor, just climbing on them. I do like that not much algae has grown on them since putting them in. I will update in the future if I see better results.

I'm a newbie to the aquarist hobby, so my experience and frames of reference are still limited. My passion for all things scientific makes the learning curve quite enjoyable as well as challenging. This is definitely in the biological chemistry realm, as well as water chemistry in general. I've had 2 uncommon snails that are particularly vulnerable to incompatible water, 1 wasn't in the best of shape when it arrived, and didn't survive for long. Looking into all of that, led me to these. And while the damage to his shell hasn't rebounded or improved, it certainly has ceased to increase, or so it seems. I have 4 tanks going and needed these for all. I've definitely noticed some changes after a month or so; the dwarf shrimp are really popping out some unusual, speckled color morphs that may not have been so obvious before. My Brazos and orange Mexican and crayfish are showing better color, the Brazos had looked simply translucent beforehand and now has some blue color popping. It took some time to see if anything happened before I could effectively review these, and best I can tell - it's helping.

These are a farce. Been in the tank for MONTHS and they dont dissolve, dont help with snail shells. Who knows about water quality because I keep my tank clean, but doubtful they help with that either. These are round stones, nothing else. Don’t buy.

Guessing it’s ok I had no problems

Got it

My only complaint is that this is sold as a 20 pack, well, I received 17 mineral balls.
