## Description

MICROBE-LIFT ALGA2.5 Algaway 5.4 Algae Control Treatment for Ponds and Water Gardens, Safe for Koi Fish, Goldfish, Plants, and Decorations, 2.5 Gallons

Review: Best algae control product - This product is the best!! Before using MICROBE-LIFT ALGA08 Algaway 5.4 my fountain would turn green within a week. It’s been 3 weeks and no green at all. I just cleaned it only to clean dirt and bird poop. Soooo pleased!!!
Review: It did what it said it would do. No more string algae - I have a small garden pond it is round maybe 30 gallons. I was having a big algae bloom in the spring with string algae and algae growing on rocks. I put a capful (and it is a small cap) into the pond. After about a week I could see a noticeable difference. Not gone, but much less string algae. After about two weeks, I added another capful. String Algae disappearing, but not completely gone. After about a month, 99% of the string algae was gone. One more capful did the job and no more string algae. I still have some algae growing on rocks, but no overly concerned about that since that stuff doesn't block my pump. Last note, My 4 small gold fish survived the treatment and my water Hyacinth I added a few weeks ago are also fine. Keep in mind that this will take a few weeks and you won't see overnight results.

### ⭐⭐⭐⭐ Works but hard to dose for smaller water features.
*by R***Y on June 25, 2026*

This was not a surprize as I read the dosing for ponds, 90 gallons and larger. My water feature is a fountain which I found holds 15 gals of water. So I did the math and I needed about .75 ml of this product in my fountain. I got a free medical dosing syringe calibrated in ml, and I add about 1 ml per week. Seems to be working nicely. My fountain is self filling and with SoCal summer coming I think I get a full water change 2 -3 per month.
