The Low Profile Strainer 1.5" Slip is designed to fit snugly inside a 1.5" slip bulkhead, extending only slightly beyond the bulkhead for a clean, unobtrusive look. Its compact design helps prevent fish, snails, and other tank inhabitants from entering your plumbing, sump, or pump, reducing the risk of clogs and equipment damage. Ideal for reef tanks where space is limited and clean aesthetics are desired, this strainer is a simple yet essential component for maintaining a safe and efficient aquarium system.
