## Description

desertcart.com: PondWorx Pond Bacteria - Formulated for Large Ponds, Water Features and Safe for Koi - Gallon

Review: Worth trying for at least a season - Pros: This really works on clearing my 1/3 acre pond. It went from brownish water to crystal clear in about two weeks. No negative impact on the pond in any way. I used a full jug since the pond is about 13 ft at the deepest and averages 6 ft. Cons: The water will start to revert back if you don’t apply again every 2 months.
Review: Worked well for my pond - better than Microbe Lift - Prof - I have 2,200 Gal pond with eight large KOI's, normally water is kept around 1,600 - 1,800 Gal. There are two 75 Gal wells as primary and secondary mechanical + biological filter as there are Matala filters + 6 Gal of K3 Filter media in there. Both wells are constantly aerated ensure full circulation and to help those bacteria breath a little better. Then another 3500 AquaScape filter + 28W UV and another external 36W UV. For the past 3 years, I've been using Microbe Lift Prof - with a kind of hit and miss result. Hit - during the period where there was less leaves (main culprit is pine needles). Miss - when there were more leaves. As a result, I would have a few weeks of crystal clear water then slowly murky from sludge after 4 weeks . . by the time it hit 6-8 weeks, I must change 30% - 40% of water. Even at this maintenance routine, I began to have green algae growing thicker on all pond walls and water began to turn light green. The foamy gunk is becoming more of an eye soar, . . . I realized that to get out of this cycle, I need to try something different. Having read a lot of reviews, I decided to give Pond Worx a try toward end of April'19. I use a a slightly higher dose than recommended, i.e., first time 16 oz, then 8 - 10 oz. weekly. - First 3 weeks - - I pour Pond Worx in the main part of the pond (where the KOI's are). It does not turn crystal clear yet but it did not get worse either. I review more reviews of Pond Worx and see someone saying the bacteria need good aeration to get better result, so, I gave it a try. - I added Pond Works to the 2 wells instead.Then, turned off the pump and let it sit aerated there for 3-4 hrs (or longer). Then turn on the pump. Within 5 days, the pond became crystal clear. Foamy gunk is still there but much less. I have maintain this weekly routine for another 6 weeks and the water is now crystal clear, algae on the walls are almost gone. So far, from W1 - W9, I did not do any major Water change. Just add more refill to replenish those the evaporated during the the very hot month of June. So far, I'm quite satisfy with this product and about to re-order.

### ⭐⭐⭐⭐ Works, but don't expect miracles.
*by O***G on September 1, 2025*

It works but I can not honestly tell you how well. Our pond had a massive algae outbreak and after using an algae control product, we had a lot of muck on the surface and on the bottom of the pond. We put in one gallon a week for 4 weeks and saw a change in the ponds health. It did not harm the large mouth Bass, tilapia or bait fish. I purchased it again to continue the cleanup. One thing it does mention. Algae control products can effect the bacteria so don't use them at the same time.
