I used the whole bottle after putting my betta in a newly setup 1 1/2 gallon tank after I put the fish in.He was in the tank for 1 day,is that alright?
Answer by ChewyJul 06, 2020
To start new aquariums, add entire bottle for up to 20 gallons. Aquarium is then ready for fish.

How much should be used during a water change?
Answer by ChewyMay 17, 2020
For healthy maintenance, add one teaspoon for every 10 gallons when adding fish, after water changes or after replacing filter media.

Would this be ok to use with my red side necked pond turtle? I have a 20 gallon tank for him

The Best Out There

I was having trouble with my tank. I used this stuff. All I have to say is this…. You would be a fool not to use this product. I used it at setup, water changes, Pump cleaning, and if my tank gets a little off. This is a all around best on the market! I love it!! I can’t brag anymore with the product. It’s my go to and always under my fish cabinet for emergencies. I love this stuff so much!!

SafeStart Plus Concentrated Works

Cycled my 135g aquarium with this product and Dr Tim’s ammonia. Very good source of bacteria. Gave 4 stars because it only comes in small bottles had to buy 4.

Great Stuff!!!

This is great stuff. I use it when I start a fish tank. I was excited to see Chewy stocking it. BUT when I went back to buy more they were sold out. I hope they get some more!!
