So I have a Waterbox Reef LX 320.7 and purchased a Pentair 80 watt UV sterilizer. This is sized for up to 600 gallon tank, but I’m at 320 total volume. Pentair recommendation for this sterilizer is a flow rate of 2700/3600 GPH (suggested/maximum) for algae. Would I stick with these recommendations given my tank is only 320 gallons, or dial the flow down?
