Sweetwater® Air Diffusers

As close to perfect as diffusers get!
Sweetwater® diffusers are the highest-quality ceramic-type air diffusers on the market today. They're machined from a solid block of glass-bonded silica. Because dust and dirt particles up to 30 microns in size will pass right through these diffusers, there's no need for expensive air filters. And with an air resistance of less than .25 psi, Sweetwater® glass-bonded diffusers are compatible with economical low-pressure blowers.
They produce a uniform medium/fine bubble and are very resistant to clogging. And when cleaning does become necessary because of a buildup of calcium precipitate or bacteria, an acid bath restores them to like-new performance. Two-year guarantee. Made in USA.

Sweetwater®: The Best
With their round grain pore structure, low resistance to airflow, uniform porosity and resistance to clogging, Sweetwater® diffusers are clearly the best diffusers available for general aquaculture aeration.

Smaller pores don't necessarily produce smaller bubbles. Sweetwater® diffusers are engineered to produce the smallest bubble possible within the constraints of a reasonable service life. In most soft water applications, they won't need to be cleaned for more than a year. Note that water pH in excess of 9.0 will shorten the diffuser life. Self-weighting when used with typical tubing lengths.

Beware of Imitations
Sweetwater® diffusers are the original 2,000ºF glass-bonded silica diffusers introduced by AES in 1978. You may come across other diffusers that copy our sizes, descriptions and even our photos! But it takes more than flattering imitation to compete with the best. Look for the name and the two-year warranty.

Compare Closely
Buy one Sweetwater® brand and one Brand X and compare for diffusion uniformity and bubble size—the most important qualities of a diffuser. Also compare pressure, clogging rate and cleaning ability. Many of our customers are still using the same Sweetwater® diffusers they bought 12 years ago!

New stainless steel uv filters and pressurized sand filters

Today at work I received 5 pallets (one 10 feet long) of new filters. There are 4x 1000 watt stainless steel ultra violet sterilizers and 8x 36 diameter triton pressurized sand filters. These are funded by the stimulus funding congress passed a couple years ago.

Wow! I'd keep these koi.

On Multiple Tank Syndrome and its remedy

"If you stop counting your tanks the multiple tank syndrome will clear up in no time!
When you don't know how many tanks you have the look on peoples face is same whether you have 12 or 12 dozen."

Freak Snow Storm Damages Hatchery Tank Filtration

On March 23 we got our first and last snow of the year. http://www.kval.com/news/local/A-truly-historic-spring-snowstorm-for-Eugene--143698986.html
No one was really expecting the snow but 7.5 inches fell at the airport and closer to 10 here in the hills. A Douglas Fir limb landed on the hatchery tank system's zapp pure uv breaking the clear union threads that attach and draining the system. This caused two tanks to completely drain. It was last years Bristol Shubunkin (Parker strain) and the late summer Matuyama x Itoh that had been raised and over wintered out side. They were high and dry for possible a day. Good thing they were cold as most revived but are now succumbing to their injuries. The Ranchu were moved inside with the bristols soon to follow.

Fortunately the system was out together with ferncos. A few twists of a nut driver and a scrap price of two ich pipe the zapp pure was bypassed.
