AquaFX Dual Electronic Finger Float Solenoid System (Tank Not Included)
Protect your entire purification setup from the silent system-destroyer: TDS creep. When you rely on a standard single wingnut mechanical float valve for your auto-top-off (ATO) system, the valve constantly drips a tiny amount of water to replace evaporation. This rapid micro-cycling forces your filtration system to turn on and off continuously. Because Reverse Osmosis (RO) membranes require sustained, high pressure to filter properly, these short bursts prevent the system from ever reaching its optimal operating state. During these brief cycles, highly concentrated dissolved solids bypass the unpressurized membrane, creating an immediate spike in impurities known as TDS creep.
While this phenomenon is famous for rapidly exhausting expensive DI resin, its damage to your pre-filters is just as severe. Short, frequent cycles cause sudden pressure spikes and rapid water hammering that exhaust your sediment cartridges and carbon blocks prematurely. Debris is repeatedly shaken loose rather than trapped efficiently, leading to clogged pores, reduced flow rates, and shortened overall filter life across your entire system.
The top-of-the-line AquaFX Dual High/Low Electronic Finger Float System eliminates this issue entirely by enforcing large, high-volume production runs. By utilizing two distinct electronic sensors, this premium AquaFX system establishes a wide, safe operational zone. The system intentionally waits until the water level drops completely to the low sensor before activating. This allows your filtration system to turn on and stay on for one long, continuous, and highly efficient production cycle.
During these large runs, your system quickly passes the initial TDS creep phase, allowing the fast-flowing wastewater line to actively flush and sweep away concentrated solids from the membrane surface. Operating at a stable, maximum pressure ensures that every stage—from the sediment pre-filter to the carbon block, the RO membrane, and the final DI resin—works at peak engineering efficiency. Once the high sensor is reached, the heavy-duty solenoid snaps shut instantly. This smart, large-batch cycling dramatically extends the life of all your replacement filters, protects your RO membrane, saves you money on maintenance, and guarantees maximum water quality for your reef.
