Submersible Pond Pumps

Covering such products as the Amphibious Submersible Pond Pumps,  and Blagdon Midi Submersible Pond Pumps these go directly into the water either in the pond or in some cases in the filter.
There are different types of submersible pond pumps some that have a Pre-Filter fitted at the intake of the pump which stops any debris clogging up the pump or damaging the impellor.
The other type of submersible pond pump is a solids handling type like Hozelock Aqua force Submersible Pond Pumps, Blagdon Force Hybrid Pond Pumps and Stingray Submersible Pond Pumps which can accept debris up to a set size depending on the pump.

Pump Wattage

Generally, the smaller the wattage the cheaper the pond pump will cost to run. But a lower wattage usually means the pond pump is less powerful, and if you are lifting water to a set height such as up to a waterfall, you may have to increase the size of the pump to compensate for the loss of water/power at that height.

Head of Water

This is the distance from the surface of the pond to the highest point that the pump has to lift the water to, for filters or waterfalls.

Waterfalls

When buying a pump for a pond waterfall or pond stream you have to allow for the head (lift) and the width of the waterfall where it drops back into the pond. You need 300gph for every 6” wide mouth of the waterfall. e.g. 6”=300gph or 12”= 600gph. 

UV Sterilisers

Like the TMC or Hozelock range will help to cut down on the green water / blanket weed in the pond, they will also help to sterilise the water.
They all have a maximum flow rate so check your pump for this and don’t make the mistake of buying a UV Steriliser to suit the pond size; it must be to suit the flow of the pump being used.

Pond Filters

There are many different types of Pond Filters on the market, very few which offer lower maintenance, and most have Foams inside them.
Pond Pressure Filters:
like Bioforce, Cyclone & FilterClear Filters are ok on small type ponds with low fish stocks. They can be put at any level to the pond because they are a sealed unit and will not leak or over flow. Most on the market contain foams and some other types of Media in them.
Pond Box Filters:
these filters generally have to go above the water level on the side of the pool or at the top of a waterfall / stream. If you don’t fit them correctly they will overflow and could empty the pond in time. Most Pond Box Filters on the market contain foams and other types of media.

All in One Pond Filter:
These pond filters are mainly suited to smaller ponds, being compact in size. They combine the pump, UV and filter in one.

Electric and Switch Boxes

A great example of this product type is the Blagdon Pond Safe range. These items are usually used near the pool side, allowing you to connect all of your electrical appliances, including items such as pond pumps, UV’s, pond lights or garden Lights, fish feeders, heaters, skimmers, air pumps and blanket weed removers. These boxes come with switches and are fused separately.

Skimmers

These help to remove debris from the water surface. Some go into the middle of the pond and are fed by a submersible pump. Others are fitted into the pond wall and connected to gravity filter system or a separate pump to be output as waste or fed directly back into the pond. Some have an extra wide mouth.

Pond Vacuums

Pond Vacuums come in different form but the best types are the electric powered type like the Hozelock Pond Vacuum which offers excellent value for money

Pond Pipe Fittings and Valves

There are basically five different types of fittings used in pond construction and they are:
Hose fittings - used on the clear and black flexible hose sizes from 3/8” to 1 ½” mostly.
Overflow Fittings - mostly used for aquariums, also sometimes on ponds. Size 21.5mm solvent weld.
Pushfit Waste Fittings are available in three sizes 32mm / 40mm / & 50mm they are sealed with a rubber seal inside the fitting they are not glueable. They are also known as 1 ¼” / 1 ½” & 2”
Solvent Weld Waste Fittings are available in six sizes 32mm / 40mm / 50mm / 82mm / 110mm & 160mm. They are glueable, but bear in mind that they will not fit the pushfit type above - although they state the same measurements they do not measure the same(!). They are also known as 1 ¼” / 1 ½” / 2” / 3” / 4” & 6”. These are the most commonly used when building ponds.
Imperial Pressure Fittings are also solvent weld and are the very best fitting to buy, they have a thicker wall and harder wearing. They come in sizes up to 8” but mostly used from 1”upto 4”. They will not fit any of the fittings listed above; in other words, you can’t mix and match the various types of fittings available, if you start with pressure, you need to continue with pressure, if you start with solvent weld, you need to use all solvent welds.
You can sometimes convert from one type of fitting to another, but it’s not always possible and it’s less messy if you stick to the same sort. We also stock Metric Pressure Fittings which are more commonly used In Aquarium Plumbing
Air Pumps come in many different sizes and can be used for creating large amount of air for your pond, fish or the filter. For the smaller pond there is the Pond Air Pump range and for the bigger ponds there are the Koi Flow Air Pump and the Hi Blow Air Pump ranges.

Bottom Drains

A bottom drain is the dome shaped product you sometimes see in the bottom of some ponds. They are installed in larger ponds and are connected to the filter. The water from the pond is drawn into the drain and pulled into the filter. This action keeps the bottom of the pond continuously clean without ever needing to be cleaned with a vacuum. These can only ever be fitted to a gravity feed system.
