I bought this filter as part of a kit sold by Reef Nutrition. I have two aquaculture’s as that’s what was recommended. One backs up the other. Both cultures are thriving however the one with the filter is a lot less maintenance than the other. The water is clean, no green particles floating in the water which greatly helps with the fry tank cleanliness and helps when “counting” the rotifers and straining them. I’ve ordered a second filter for the backup culture.

No explanation given that the “missing” part is not necessary to operate the product, had to contact support first before I learned that it should be used that way. Another concern is how small the filter is. It would require more frequent cleaning compared to the original kit.

2 weeks in and I love it. Does what it’s supposed to do. Fits right on a 5 gallon bucket. Keeps the water clean. Doesn’t trap any rotifers. Still clean the bucket every other day and clean the filter out every few days. Works great. Rotifer culture is thriving.
