AIR PUMP for 5' water column
I have a 6' tall counter current air stone skimmer I made a couple years ago, and am looking to up grade the air pump I'm currently using. It will need to push air through multiple airstones at 5' depth of water.
I am using the Tetra 300 'deep water' model pump with 4 airstones, but it's getting near the end of it's life, and I'm looking to improve.
Could use some 'FIRST HAND' opinions on pumps.....
The Alita 40 had been my front runner, but although a serious pump, I have doubts if it can handle the depth requirements.
The Coralife Super Luft Air SL-65 seems to say IT CAN, BUT besides the noise, it seems to have mixed reviews for longevity.
Price isn't really an object, at least not as important as quality.....need something SAFE, and will last....at least 2+ years of continuous service. So if any of you fine folks have air driven skimmers, or deep ponds they're aerating, I'd love to hear some suggestions. All the best,
