DrTim's Aquatics Re-Fresh for Reef Aquariums – 100% Natural Fish Tank Sanitizer & Revitalizer Conditioner Solution Fresh, Crystal-Clear, Sparkling Water - Size 8 oz Treats 480 gal

This stuff is the best in conjunction with the Dr Tim's ammonia. Cycled a 88 gallon red sea in record time. Trust me and just buy it

Great stuff

Great for starting up a salt water tank!

Always use this when starting a new tank

This stuff is absolutely amazing. I use it when I set up a new tank, or even sometimes after a water change just to beef up the beneficial bacteria. You can add fish immediately, no more waiting weeks for a tank to cycle. If you worried about over stocking, and about to add another fish, just add another bottle. My tank has never looked so clean and it totally skipped the "ugly stage" that most tanks go through. I always keep an extra bottle on hand just for incase moments. Once I needed to set up a hospital tank for a sick fish, and I didnt have time to wait for the tank to cycle, i just added this and then was good to go. Everyone who has a tank should keep this on hand at all times. It's amazing.

Me agrado qué purifica el agua, lo que no me gusto es que para lo que lo necesitaba que era quitar las algas no sirvió.

good。Very good product

Claims to start the tank cycle but this never occurred with our tank. Paired this purchase with their ammonia chloride to feed the bacteria.Readings never budged from 2ppm ammonia. 0 nitrite. 0 nitrate.We were doing a fishless cycle so expected it to take awhile, however the cycle never even began.Buyer beware if you're looking for a decently paced fishless cycle. Product doesn't do as it claims.
