TANK FILTER BUYER’S GUIDE
THINGS TO CONSIDER
When making plans to buy a tank sifter, you need to consider the volume of water in your tank, the number of fish in the tank, and the ideal tank that will work best for the receptacle.
Volume of Water
You need to know how much amount of water you have in your tank so that you’ll get a sifter that matches that quantity. For instance, if your tank is up to 5000 gallons of water, you might want to consider going for the OASE BioSmart, and so on.
Number and Size of Fish
The next thing to take into consideration is the quantity and size of your fish. Are they small and many? Or are they fee but large. This will help you know which one to choose based on the description of the sifter’s pack.
TYPE OF FISH TANK SIFTER
Your choice of sifter should be based on how you want it to function. Do you want it hidden inside the water or exposed? Do you want the water to always pass through the sifter before entering the tank or after? Or, is a waterfall or fountain cascading right into your fish tank? Knowing these answers will help you identify which choice to make. Nevertheless, the ideal sifter is a type that operates throughout the day, with at least one circulation each hour.
HOW TO KNOW THE IDEAL SIZE?
Tanks Without Fish
To know the right size for a rectangular or square-shaped tank, without any water or fish in it, use the below formula;
Length x Breadth X Depth X 7.5 = Gallons of Water
However, if it is an oval or round-shaped tank, measure the tank’s diameter, divide it by two, and you’ll have the radius of the tank. Once you have the radius, calculate it using this formula below;
3.14 x Radius x Radius x Depth x 7.5 = Gallons of Water
If your tank comes with two depths, then you’ll have to measure tank’s depth, at separate dimensions. And to arrive at the average size of this two depths tank, add all the measurements together, and divide them by the number of times it took you to measure the tank’s depth. The answer you’ll get is what you’ll use to know the right gallons of water that will fill up the tank.
If it’s an irregular sized tank, you can know the average breadth by measuring the width at different spots, adding the result of the measurements together, and dividing the answer by the number of times you measured the fish tank’s width. The answer you get is going to be the size of the gallon; your tank will need to fill up. The same is applicable if the tank has many depths, with an irregular shape.
For a Fish Tank with Water
If you own a fountain or waterfall, here are the things you’ll need to consider.
- The tubing’s dimension
- The quantity of the tubing’s 90° bends, valves, adapters, and fittings.
- The length and width of your waterfall
Having these data at hand will help you in accurately arriving at the flowing speed of the water, which will be needed to take it to the top.
Also, you need to understand that the breadth of the waterfall is what will determine the running speed. Thus, the pump of your waterfall ought to flow at least 125 gallons of water every hour, for an inch of breadth.
However, if you’re looking for a more tranquil flow, I’d be ideal for you to make use of 100 gallons of water every hour or less, against every inch of breadth. Below is the formula on how you can calculate the flow rate properly;
Inches of Breadth X Gallons of Water Moved Per Hour = Flow Rate
And if you’re looking to estimate the total dynamic head pressure, you can do so by using the below formula:
H = The Height (in feet); T = The total distance of tubing (in feet); A = The total number of 90° angle bends; B = The total number of all the valves, and other adapters or bulkheads used with the tubing; H + (T/10) + (A/2) + (B/4) = Estimated Head Pressure
For Tanks with Fish
Unlike the case of an empty tank, there is no real way to calculate the size of the sifter, which will be adequate for a tank with fish load (number of fish).
Nevertheless, you can start by making your choice in between sifters that can operate with five inches of fish, for every five gallons of water. And also, remember that the fish in your tank will grow up someday and multiply, thus, choose a size that will be spacious enough even when they have all grown and multiplied.
Put differently; if you own a tank of 1,000 gallons, with up to 150 tiny fish inside, you should get a tank that is bigger than that dimension at least by 1.5 percent. Overall, always go for large-sized tanks, in anticipation of the growth and multiplication of your fish.
TYPES OF TANK FILTERS
There are three forms of tank sifters which include:
- Submersible tank sifters
- External tank sifters
- Tank skimmers
And these sifters, depending on the what they were built with may work using the technical or organic filtration, and an ultraviolet clarifier (UV-C).
This form of sifter works by allowing water to move through a physical cleansing object like foam block, which then assists in taking off debris and dirt.
An organic filtration system is made up of good bacteria that assist in transforming lethal toxins such as nitrites and ammonia from fish waste, and decaying debris, right into nitrates, which tank plants often use as food to survive. However, for this form of sifting to work, one needs to maintain an equilibrium in the ratio between the waste items in their fish tank, and the bacteria.
This form of purification involves the use of ultraviolet light to destroy microscopic organisms such as protozoa, algae cells, and any other lethal parasites or bacteria in the fish tank. This often works through the penetration of the ultra-violet light rays through the cell walls.
Submersible Fish Tank Sifters
This form of sifter is just the type that filters water from things like debris before it goes into forming a clog inside the fish tank. It is often considered the easiest and placed in a hidden position beneath the fish tank. It’s an ideal option for those with small, performed or forms tanks.
Submersible sifters could work using a technical or organic filtration method. If it isn’t included in yours, you could buy it separately and attach them to the sifter. Nevertheless, you need to detach the submersible sifter from your tank from time to time, to clean it properly. You don’t want the waste trapped by the submersible sifter to go back into the water.
External Fish Tank Sifters
This is quite the opposite of submersible tanks, as they are placed right outside the tank. As a result, they don’t consume enough space, and are often large, making it an ideal for larger fish tanks. Plus, they are known to be durable, perhaps because of how they are placed outside.
However, given that water in the tank goes through the external sifter right from the pump, these sifters are often exposed to coming in contact with clogs from debris that are floating in the water. That’s why it’s ideal that you place a pre-sifter, something like a tank skimmer, on the receiving part of the pump; to save your external sifter the stress—and speaking of tank skimmers.
Fish Tank Skimmers
This are pre-sifters, that helps in taking off about a more significant percentage of leaves, and other forms of debris that may be floating in your fish tank. Most times, they are placed underneath the tank and attached to the tank liner.
Last but not the least thing you’ll have to consider is in the area of energy consumption. Given that you’ll have to operate your sifter throughout for optimal results, you can’t afford to purchase sifter that consumes more watt. Put differently, go for those that will help you cut down on your electrical bills, at the end of every month.
Based on a recommendation from the COO and Head Technician of AZTanks, Mark Charles Moser, external pumps are known to use lesser energy than submersible pumps, most notably in the 3,000 GPH to 6,000 GPH category.
According to him, an external pump that is predesigned with a 6,000 GPH capacity, would perform well at only 450 watts of power consumption. Whereas, a submersible pump using the exact capacity would often need about 750 watts to 1,200 watts to operate at an optimal state.
