I've used this in my koi pond for 4 years now and it keeps the water maintain and clarity of the water clear i would recommend this product to anyone.keeps fish happy and is 0great for the money

It does really work

I've had a small fishpond off my back patio for about 20 years and I've purchased all kinds of additives for the pond water, and thought that most were a waste of money, but this one is the GREATEST! I'd drained and refilled the pond and applied this product as directed in the early summer. I have a submerged pump and filter system and I usually look at the flow of water from the small pot to determine when to clean the filer, but I always do it once a month, except this this last time, a couple of weeks ago. It's been extremely hot and probably 2 to 3 months since I'd cleaned the filter, and I was shocked. The filter was CLEAN, and it didn't need cleaning. I ran a small wire through the system and blew it out with a hose, as I always to, and there was a small amount of residue in it, and I was DONE! Thank you AQUASCAPE for your expertise in chemicals for this amazing product!

Cleared up some heavy algae in a matter of weeks, used it sparingly and got awesome results. Fish are in great health and pond water is now perfect.

I have a 900 gallon pond (9x12 and deepish) with probably 30+ fish of all sizes in it. Needless to say, it turns greenish in the summer. I use Nualgi weekly, but I felt that it needed a little more bacteria. I had great luck with the cold water bacteria by Aquascape in the spring startup, so I bought some of this. I had a little bit of trouble trying to figure out what product to buy - as they have others that look like they would be the right choice, too. However, this seems to help. My water is greenish -but it's mostly visible when pulling water out in a white bucket - it has a greenish cast. I can see my fish quite well, so it's doing what I need it to do. Dosing couldn't be simpler. 9 pumps for 900 gallons. Easy. The one thing I do not like about this product (and the Cold Weather Bacteria pump) is that when you initially open them, you will get sprayed in the face. Open it inside a bag or something to keep it from spraying all over. And, after pumping it into the pond, it's drippy for a while. I'm not a fan of that, but it's easy and it works, so I can overlook it. I'd recommend giving this a try if you want to clear up your water. If your pond isn't a science project - you're not doing it right.
