This livewell aerator spray head is exactly what you need to keep your baitfish healthy and active in your boat's livewell. It's designed to fit standard 1-1/8 inch inner diameter hoses (that's about 28.58mm) and can handle tank walls up to 1-1/4 inches thick. The adjustable spray pattern lets you control how the water circulates and oxygenates - you can set it for a gentle mist or more aggressive aeration depending on what your fish need. It comes with a stainless steel hose clamp that ensures a tight, secure connection without leaks. Installation is straightforward - just slide it into your existing livewell system and tighten the clamp. Proper aeration makes a huge difference in keeping your bait lively throughout the fishing day. Whether you're a weekend angler or serious tournament fisherman, having reliable aeration equipment is crucial. This spray head is built to last and does the job without any complicated setup. If your current aerator isn't performing well or you're setting up a new livewell system, this is a simple upgrade that really works.
