Aquascape MAINTAIN Water Treatment for Koi and Fish Ponds, Easy To Use, Powerful Blend of Beneficial Bacteria, Phosphate Binder, Flocculent, and Detoxifier, 16 ounce / 473-ml | 96058

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!

Has done really well for my pond

This helps to keep my pond clean and healthy for my fish.

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.

Used step 1,2, & 3 along with a string algae buster all aqua scape products all this year. It was my first year having a koi pond. These products made a world of difference. Used as directed and didn’t harm my plants or fish.

Excellent value. I use it in my Cichlid tank and my goldfish tank.Able to stock with TWICE the amount of fish!Excellent to use whenever doing a water change!

Keeps the water looking clear . I have no idea how it affects the fish …. All is well so far

I love that it’s like a catch all pond treatment for spotless water quality, but I like it better in my automatic dosing system. This you have to add manually where as the dosing system has a bag that gets replaced so often depending on the size of your pond or tank.
