The general rule of thumb in aquarium keeping is to have no more that one inch of fish per gallon of water. Thus, if you had a twenty gallon tank (with no substrate or rocks to diminish the total water volume), you could have five 4-inch fish. This formula also assumes you will change 25% of the tank volume each week. See What is a water change? Why is it important? for more details. Realistically, however, you will need to consider the following factors when choosing what size tank to purchase:

We like to give our guests lots of air, so a 15L is standard. Off course you can choose to have a 12L or 10L if you wish.

Answer: Most of our heaters require a 100 lb. tank or larger unless they state otherwise in the heater description. If you need more information please go to our Propane Vaporization Chart and call your local propane dealer. Answer: Vent free heaters are designed to burn as clean as possible. However, there may be particles in the air from other household materials that when mixed with the combustion air the unit is using, give off the scent of kerosene. Typical odor producing prod.

For single-family homes, tanks typically range in size from 500 to 1500 gallons of wastewater storage capacity. For a one- or two-bedroom home, a 1000- or 1200-gallon tank is common; A typical 1000-gallon concrete tank measures about eight feet long by four feet wide and six feet deep. Check with your local building department for actual sizes needed.

The tank size assists the technician in determining gallons of product, water, or air space in the tank.

The general rule of thumb for freshwater is one inch of fish per gallon of water. This means that a 20 gallon tank shouldn't hold more than five fish that can grow to four inches each. There are other factors that can affect how much space a fish needs such as how territorial it is, so please check with your local fish store before adding fish.

I suggest using an HP tank with it because the Shocker, as well as 99% of all other guns, are designed to work with HP tanks. LP tanks are only needed on a specific type of Angel, if you don't own that then don't worry about it. Some LP tanks aren't fast enough to perform well on a Shocker.

The first step is to determine how much lumber you’ll dry in a year. Then figure your average drying time for each of the species you’ll be drying, and you can calculate the size kiln you need from there. For example: you need to dry 500,000 board feet of oak per year. Fresh off the saw, oak takes about 28-30 days to dry, so you’ll be able to do 12 loads in a year. Each load will need to be 42,000 board feet to give you the 500,000 board feet you need for the year.

Quarantining new fish is a good habit for all aquaria, but is not absolutely necessary for success. Quarantining is simply keeping a fish in a separate tank for long enough to be certain that it is disease free. Many beginners do fine without a quarantine tank, and object to the cost of another setup.

The minimum size of an enclosure for a single adult bearded dragon is 55 gallons. For babies and dragons under 10 inches a 15 or 20 gallon enclosure is best.

With the exception of the outdoorsman model which can run from a 20 lb tank, the indoor gas heaters require a 100 lb because of the speed at which the gas flows to the heater. The faster the propane flow the colder the propane gets (experience this by blowing air gently from your mouth to your hands, then blow some air as hard as you can into your hands - the faster moving air is colder than the slower moving air).

Weight distributing is based on the amount of loaded tongue weight the trailer has. To purchase the correct size weight distributing hitch (WDH), you will need to first load the trailer as you would tow it down the road and then have the tongue weighed. You can weigh the trailer tongue by using a bathroom scale or taking it to your trailer dealer to have the tongue placed on a tongue scale.
