The 1.0' is available in 50 ft rolls. Choose 3/8" or 5/8" for Hakko 25L. The outlet port on the HK25L is 5/8" so the 5/8" hose will connect directly. However, you can reduce down to 3/8" with an adapter reducer (not provided) to use the 3/8" hose for HK25L. Choose the 5/8" weighted air hose for Hakko 40L through 100L. The outlet port on these pumps is 5/8" so the air hose will connect directly. Choose the 1.0" weighted air hose for the Hakko120L. The outlet on the Hk 120L is 1.0".

If you use a heavy duty 4 way manifold with the HK120L, you can use four 3/8" hose to deliver air to 4 diffusers. See the article Heat Control for Hakko.

The breeding season is weather dependent but is normally from April to July. You need one mature female and a minimum of two mature males. Place the brushes just below the water level, one above the other, at the edge of the pond. This will encourage the fish to spawn, which usually happens in the early hours of the morning, having been preceded by an evening of flurried activity in the pond. The spawning takes several hours, during which most of the eggs will stick to the brushes. It is best to put the brushes in filtered water of the same temperature as before, and the fry will hatch in 3-6 days. The small fish should be kept separate until they are large enough to be introduced to the pond. After the spawning, it is a good idea to separate the brushes from the brood fish, otherwise the eggs will be eaten. Note: Our spawning brushes are made from a soft material that won't harm your fish. Do not use filter brushes for this purpose. 2- 52" Black Knight Spawning Brushes (568 words) - [Aqua Ultraviolet 40W Classic Replacement Quartz Sleeve A10040 | USA Koi](/content/products/aqua-ultraviolet-replacement-quartz-sleeve-40w-classic.html): Genuine Aqua Ultraviolet replacement quartz sleeve (A10040) for the 40-watt Classic UV sterilizer.

Common salt, Sodium Chloride (NaCl) is commonly used in the health care and maintenance of fishes especially Koi. Salt is useful in eliminating parasites.  It will eliminate seven out of nine types of parasites that are commonly found in Koi ponds. Most fish have an internal salt concentration of 1.0% or 10 parts-per-thousand (ppt) which is higher than their water environment.  Osmosis causes water to transfer from the lower salinity of the pond water into the tissues of the fish. Addition of salt will lower the osmosis pressure. This reduces the effort of the fish in eliminating the excess water.  The saved energy is then available for use by the fish’s own immune system to fight diseases.  On the other hand, if the salinity of the water environment is close to the internal tissues of the fish, the osmosis pressure will reverse and cause the fish to die of dehydration. Salt concentrations of between 0.3% and 0.5% (3 to 5ppt) will upset the osmotic balance of some parasites i.e. the parasites’ cells will dehydrate.  Salt concentration of 0.3% are effective at detoxifying nitrite and concentrations of 0.25% or higher have been used to control string algae. Nevertheless, salt can cause pond plant damage as the concentration increases.  Floating plants (water hyacinth, water lettuce, etc.) are affected at lower concentrations than most bog plants.
