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

I started using this when the algae situation in my reef tank got bad, it definitely helped and I've been adding it to my tank every time I do a water change since then and have seen great results.

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.

Honestly I have heard good things about this solution, but my experience was not congruent with others' experiences. I bought this bottle to treat my 65 gallon reef setup (full of live rock, over 70 pounds), and enacted the fish-less cycling procedure with Dr. Tim's own ammonia bottle. Now I do have a 20 gallon sump as well, so when ammonia would not read down the first three days (and no nitrite reading), I thought maybe I didn't have enough Dr. Tim's for my system. So I went to my local LFS and bought a bottle for 30 gallons and added this. Still, no help. But, I did put Seachem Prime into my tank originally since I had rinsed my dry rock with tap water outside and wanted to get rid of the metals (All the rest of my water was RO/DI). I believe the prime converted the ammonia that I had originally inserted into ammonium, thus giving me incorrect readings on my API Ammonia tests since those tests measure a combined Ammonia and Ammonium (Ammonium is not toxic to fish, at least in low levels). So after contacted Dr. Tim's support, I kept going and trying to see what would happen. I didn't put much trust in my ammonia readings, but my nitrite readings were very low (either 0 or .25-.5 PPM) for more than a week, and trace nitrate. Well, I decided to try to add a damsel at this point because according to Dr. Tim's, I should be cycled at this point (as their product actually suggests you add fish immediately, but I didn't want to kill the fish or put it through stress). Long story short, it's been over 2 weeks, I have 5PPM nitrite readings, 5PPM nitrate readings, and ammonia readings that I cannot trust. All this with one fish in a 85+ gallon setup and minimal feeding. This does not sound like a cycled tank, and clearly their nitrifying bacteria is not doing its job (but clearly the ammonia converting bacteria is). They also do not have a money back guarantee (they literally told me that it was not a water quality issue, which makes no sense), so buyer beware since this product is not really that cheap. I hope I am an exception though since I never write one star reviews, but I just wanted to save some people from unnecessary grief (if your experiences mirror mine). I will be cycling my tank the normal way now with a dead table shrimp and wait it out.

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.
