Is this product safe to use with shrimp and snails in the aquarium?
Answer by ChewyDec 14, 2020
API CO2 BOOSTER is safe for use with shrimp and snails. Dosing directions should be followed. There is not enough chemical change in the water to affect water parameters.

Bottles half full

I received my package today. The box was wet. I thought it might’ve rained on it. Which was ok it wouldn’t have hurt anything. I open the box and the filling paper of the box is soaking wet and both of my bottles of CO2 had soaked through the box. 2 bottles were missing their lids and now I’m stuck with 2 bottles that only has half the product of what I paid for. As for how well it works this was my first time ordering it. How the lids managed to come off in the box I have no clue. Unless they were thrown in the box without lids. The box itself was pretty beat up and smashed also which still shouldn’t have made the lids twist off.

It’s ok but time will tell

I have a new setup about 3 or 4 weeks old so I really can’t say but I do think it helps with algae on the glass.

Love this stuff

I have a 20 gallon, planted betta tank and I did not want to have to mess with an entire CO2 system. My plants weren’t doing so well and then I found this stuff. So much easier than a CO2 system if you have a low maintenance setup and my plants look beautiful now. They’re thriving!

Great for plants

This product works great!, I could tell the difference in my plants. They're looking more lush and vibrant.

so far so good

After a horrible experience with Co2 injection drastically lowering my PH and killing most of my fish, I though I'd give this a whirl. We'll see how it goes.

I think it works.

I'm using this product along with grow lights and various fertilizer brands for my planted aquarium and have seen a significant difference in several of my plants. I think they like the new supplement routine.
