One of the key advantages of the AlphaONE LH 2.50 Filter is its revolutionary design that maximizes flow and minimizes energy consumption. The multiport valve is a significant flow robber of filters. GC Tek bypasses it in normal filtration mode, allowing for more significant pond turnover without using more energy. This leads to significant cost savings and more transparent water.
The AlphaONE LH 2.50 Filter comes with all options included as standard equipment, including the following:
• Air diffuser assembly
• Backwash assembly
• AlphaBio1 media
• Easy-Lock union assembly
• Multiport valve with plumbing
• ALISS
This means you won't need additional equipment or accessories to get your filter up and running. Overall, the AlphaONE LH 2.50 Filter from GC Tek is a top-of-the-line option for pond owners looking for an energy-efficient and reliable filter. Its revolutionary design, durable construction, and ALISS system make it an excellent choice for ponds up to 5000 gallons. With all options included as standard equipment, it's a wise investment to provide you with years of trouble-free performance.
Using the AlphaONE LH 2.50 for several months, and I’m impressed. It keeps the beneficial bacteria alive during power cuts thanks to ALISS, and the internal vortex design pushes solids to the bottom for easy backwashing. Energy savings are noticeable, and setup was straightforward—with everything included from the start.
Perfect for my 5,000‑gal pond. Great flow (70 gpm) without high energy bills. Easy to hide because of its compact 21″ × 34.5″ size. Clean water, happy fish.
