These aeration kits provide quick and safe gas exchange. Help remove carbon dioxide and hydrogen sulfide while allowing water to hold more oxygen. Aeration makes ponds more suitable for fish, lowers surface freezing, promotes efficient biological filtration in your pond, and helps retard algae growth. Easy-to-install kits.
The 50-lb Kit circulates water in ponds up to 4,000 gallons, delivering 0.8 CFM at a 24" depth. Uses 25 watts at 4.5 psi. Includes 12 ft of weighted tubing, 2 clog-resistant airstones and supports 50 lbs of koi when diffuser is at 48" depth.
100-lb Kit circulates water in ponds up to 8,000 gallons, delivering 1.8 CFM at a 24" depth. Uses only 50W at 4 psi - much less than a heater. Includes 20 ft of weighted tubing that stays on the bottom of pond and 4 clog-resistant airstones. Supports up to 100 lbs of koi (e.g. 100, 12" koi or 30, 20" koi) when diffuser is at 48" depth.
200-lb Kit circulates water in ponds up to 12,000 gallons, delivering 3.0 CFM at a depth of 24". Uses only 90W at 4 psi. Includes 40 ft of weighted tubing and 8 anti-clog airstones. Supports up to 200 lbs of koi when diffuser is at 48" depth. Airstones create less than .25 psi resistance.
