SunGrow Betta Balls, Water Conditioner with Over 30 Beneficial Elements for Tropical Fish, Freshwater Fish Tank pH Balance Decor, 0.3” Betta Fish Tank Accessories, 10 Pcs per Pack

They work I geuss hard to tell. My fish seems Healthy. I didn't clean My fish tank thoroughly though, that kinda pissed me off when i read the instructions.

First of all I definitely got more than 10 balls in my pack and yes they are quite tiny but totally worth it.... depending on the price. I bought these for just under $10 and was shocked to see they're now $18 as that seems quite high to me. Honestly though they really work. I won't lie I love my betta, Walker, truly I do but I HATE tank cleaning and can be quite lazy with it.I did a home upgrade for Walker about 4 months ago and after soaking as directed (I soaked mine overnight though just to be extra careful) put about 4-5 of these in my 3 gallon filtered tank. I also have 1 full grown blue ramshorn and a couple baby blues (yes avid aquarists I am aware of snail parameter requirements and do snail control but leave them be when they're small and can't add that much to the bio load) that have popped up since, obviously snails really help with algae control so they have been doing the work there but these balls aren't supposed to clean that anyways. However I have not done a manual clean or even partial water change since the tank upgrade although I have added betta treated water about 3 times due to evaporation. BUT I do test my water more often and even checked it this morning and it was PERFECT.. in fact has been every single time. My water is crystal clear, gravel isn't dirty, bioload obviously hasn't been a problem and algae production is incredibly low like almost nonexsistent (and I know this because I have to supplement my snails with algae wafers on an almost twice a week basis).These perfect parameters which have my betta & ramshorns in amazing health and tank immaculate are most definitely due in part to these tourmaline balls (snails also love to suck on these btw). But it should be noted that I also use Catappa (betta) leaves and calcium wonder shells as well as having two large marimo balls and an amazon sword plant in my tank, each of these items has it's own benefits and plays a role that together creates this essentially perfectly balanced underwater eco system.

Didn"t seem as the fish liked these

I got these with a bunch of other items for my 5 gallon my 10 is still a new set up. But from what I can see my male betta in my 5 gallon is loving it. I have had it in there for a while and he’s super active and loving his life how he pleases but it hasn’t hurt him at all.

If you keep your Bettaas in one gallon tanks, this is way too much.One ball is for 10 gallons, can't split it hard as a rock.

I bought these because I was told they are beneficial for bettas. Followed the instructions of letting them soak in a cup of his tank water overnight, then dropped them into the tank. I only put 4 of them in, he's in a 25g with about 12 ghost shrimp.Legit not even a few hours later, I found Elvis laying at the bottom on his side. HE NEVER DOES THIS. My betta is a super healthy, happy, hangry, active boy. I monitored him for several hours, tested his water parameters, everything. The ONLY difference / change in the tank in the past week was adding those four tourmaline balls. So, I hastily removed them.Within a few hours, Elvis was back 'up and running', wanting food, at the top of the tank, swimming around, being social. I do not know if it was these magical balls or what, all I know his, bruh did NOT like them. And I thought my beautiful Elvis was going to leave the building. =(I'm sure they would work fine for some fish or maybe adding them BEFORE you add fish is a 'thing'??? Betta are very hardy so it just creeped me out to see how these balls made him act like a zombie. And no, he wasn't sleeping. He sleeps at the top of his tank in the multiple hammocks I created for him.Anyhoo. Betta parents beware, this one made my dude seriously screwed up. He's back to good now but man was I scared!!!

I bought these back in December for a natural filtration Beta tank. These are really impressive! When I upgraded my tank size I didn't add any additional and noticed the water just didn't look as clear as it had before, no matter how regularly I cleaned and did water changes. Last night I came across the rest of my bag of these and added the recommended number per package instructions. Overnight my bowl went from looking clean but a little cloudy to crystal clear. The Beta doesn't mind them at all and they're pretty small and not particularly noticeable in the tank-scape. I will be buying again.

So I did get these along with some sungrow betta leaves, and I put them both in at the same time so I don't know which thing made the most difference (it was probably both though). The leaves are also under $10, so I spent like less than $20 and my betta is back to his hold self. I went on vacation and left him with a family member, and he got a really bad case of fin rot and I think something else (he was swelling up). He was on the brink of death and I managed to bring him back, but he's never quite been his usual active self after that. He would always eat, but he was very lethargic and would pick a spot in the tank and stay there for hours, when he used to greet me and swim around all the time. I've had both these in the tank for 3 days, and every time I see him he's in a new spot! He no longer lingers around the top just sleeping, he's actually exploring again. I was skeptical that these things could make any type of difference, but they definitely did. I'm sure it will only get better as he continues to heal (which both these products claim to promote a healing environment, cool!)
