Energy-booster — Calcium-enriched, this source of nourishment balls by SunGrow help in activating the muscles and developing strong bones. The balls for freshwater fish like neon tetra, guppy, dwarf gourami, and others can make them energetic. An agile and active breed also multiplies in higher numbers.
For Happy Fish — These SunGrow water conditioner balls for fish living in tropics help vitalize metabolism. The popular harlequin rasbora and tiger barb start nibbling on them as soon as you drop them.
Essential For Optimal Balance — Our gray pellets are an assurance to maintain balance in their freshwater habitat. In just a short span of time, you will notice a considerable difference in your fish. They will become more active, and their fins will become brighter in color.
Not Just For Fish — If you have live plants in your tank, you may notice a significant increase in them as well. Our balls consist of several essential items including iron, and manganese. So, add these balls and see the difference for yourself.
Aquarium Decor That Goes Well With Live Decor — These energy balls are discrete and look great in your tank. Its round shape and color fit perfectly to any theme you want to convey by giving a distinctly rustic look and feel. If you place these balls in a substrate near plants, plants will also soak up the elements.

Didn’t kill my fish and snails…
Didn’t kill my fish and snails. I don’t know the reason to soak for 2 hours before putting into tank? Placed in tank, anything to have my fishy friends to look and feel their best, look great and fish haven;t died. Fish look great and they don’t talk to me so I don’t know how they feel. My fishies are very active.

Ignored by fish etc
Good price and fast shipping but my fish and my snails have not touched it. It’s been over a week and they won’t touch it. I put 2 in different areas of the tank but they don’t want it.

Super small
Smaller than actual photo it looks on the site. They work great after soaking them in water for up to two hours in a bowl before you put them in the water of the aquarium.

A good thing
Value for money seems to be decent enough. The snails and shrimp flocked to it right away. My two mystery snails are often on these balls at least twice a day I guess for the calcium in their shells.. same reason for the shrimp. it doesn’t seem to be messing up the filter or making the water too hard. I think this is a pretty good calcium supplement for the shrimp and the snails. Good item. Honestly not sure what else to say other than it arrived safely.

Just get crushed coral
After a week of slowly dosing my tank with more and more of these over a week to the point where I had 19 in there. The kh finally seemed to go up about half a degree for 1 day. Then dropped back down to where I started and my shrimp were lathargic and a few died, I removed the balls and they all became active again. Idk if there’s copper in here or what, but whatever this actually is it’s not enough calcium to effect kh and seems to have some harmful minerals to shrimp. 0/10 would not recommend to a friend.

Have them on my fish tank for over a month. No issue so far. Desolves too slow as expected. However, the packaging was poor!
