Smart Design with Built-In Security Features
All of the AlphaONE filters utilize the Omnifuser design technology that eliminates slotted PVC pipes in the filter. The Omnifusers allow the heavier solids to be easily purged from the bottom of the filter during backwash since they are sitting at the lowest point in the filter.
- The 2.50cu.ft. AlphaONE is the perfect filter for ponds up to 5000 gal. and fish loads up to 125 lbs.
- Flow rated at 70 gpm for bio-mechanical filtration. 21" X 34.5" allows you to hide this unit anywhere. Every option is standard equipment. It is the perfect filter for the majority of ponds.
AlphaONE filters also feature the AlphaONE Life Support System, known as "ALISS", which keeps beneficial bacteria alive indefinitely during times of medical shutdowns, pump failures, etc.
The 2" Clear Union Spring Check Valve located right under the 2 HP blower provides maximum flow and has built-in unions and a PVC slide valve for extra blower security.
I’m honestly very happy with the Alpha ONE 2.50 Filter from GCTek. From the first use, it worked smoothly and delivered clean, consistent performance that I could really feel. The quality is excellent, and it gave me complete confidence that I made the right choice. It’s one of those purchases that truly brings satisfaction and peace of mind—highly recommended.
I don’t rush into buying things, but this one earned my trust quickly. The quality is outstanding, and the experience has been nothing but positive. I’m honestly excited to recommend it to others.
I always look for good quality, and this one truly stands out. Everything feels strong, reliable, and well-made. It’s definitely worth trusting.
I’ve had this running on my 3,000-gallon pond for a few months now. The ALISS feature gave me peace of mind during power outage last week—my water stayed healthy. Maintenance is easy, and flow stays steady.
This is not my first purchase, and I am very happy every time.
This was my first time ordering, and I’ll be honest—I was a little unsure at first. But after receiving and using the Alpha ONE 2.50 Filter, I was genuinely surprised. The quality and performance were much better than I expected, and I immediately felt that trusting this website was the right decision. I honestly thought to myself, “Why didn’t I order this earlier?” If you’re thinking about it, just order once on my recommendation—you won’t regret it.
I am extremely satisfied with the Alpha ONE 2.50 Filter. The performance is smooth, reliable, and exactly what I was hoping for.
Very happy with this filter. Setup was easy, water cleared fast, and backwash is simple. Good build.
