This is my 3rd one. I use them in all 3 of my freshwater aquariums. Buy it, you won't regret it. Getting ready to set up a fourth aquarium, and will be purchasing another one.
I'm glad UNS decided to have a middle ground filter between the Delta 60 and 120; the Delta 90 is what I needed for my 60P tank. Although the Delta 60 is rated for tanks up to 27 Gal, it didn't provide enough circulation once plants grew enough to slow down water flow. The Delta 120, though I didn't get one, is too overkill just by looking at the stats. Enter the Delta 90: provides enough circulation to my whole tank without leaving stagnant spots. Always go a bit higher what the manufacturer recommends in a filter because it just won't be enough! IIRC, this is an UNS-branded Shiruba XB-308 but I decided to go with the Delta just because aesthetics. Parts should be interchangeable as far as I'm concerned. If using this tank for a 60P, remember to adjust flow just enough to not cause a black beard algae outbreak (that thing loves strong currents) but strong enough to leave your tank without stagnant spots.
I was hesitant to purchase this filter since it hadn’t been out in the market for too long and there weren’t many reviews. I am very happy that I did because so far, it’s been working great! I’m using the Delta 90 for my 20 gallon tank which might seem like overkill but with the adjustable flow, it’s nice knowing I can dial it back a bit in regards to the output. Even though I’m using my own lily pipes, I love that it comes with a spraybar AND a jet stream outflow attachment. So far, I have no complaints. I have purchased many UNS branded products from here and I have not been disappointed once. At this point, UNS is probably my favorite brand of aquarium equipment.
It’s a workhorse and yet it’s quiet. Loving it so far!
First time using a canister filter so far, I’m hooked it’s quite great flow & very professional feel to it.
