Python Siphon and motor

those siphons also fill the tank as they are.
there is no need for an extra pump.

There is a valve on the part that attaches to the faucet, flip the valve one way, and it drains the tank, flip the valve the other way and it fills the tank...
 
just like the other guys said, close the valve and it will fill the tank as fast as your water flows. you wont regret getting it though, works great.
 
The above suggestions will certainly work if you want to put tap water back into your tank. But who does that???

I use a Python to empty (siphon) water out of the tank and a Mag 9.5 or 7 to pump in new saltwater. I made a simple little adaptor from two CPVC connectors from Lowes.

This simple DIY takes two parts and costs about $2.50 and it allows you to connect a regular hose to your MAG pump (I use a Pythontm, which is a clear hose with a regular hose connection, but a regular garden hose will work just fine). Note that these types of adaptors are already available in BRASS, but we wouldn’t go there. I could not find these parts at Home Depot, but did find them at Lowes.

Parts:

1 - Hose Adaptor (3/4 hose x ½ st. adaptor CPVC)(P/N 53128) $1.28
1 - ½ adaptor (1/2 female NPT x ½ slip CPVC)(P/N 50305) $1.02

Here’s what they look like:

By the way, this is CPVC, not PVC. It is a light tan color (not white) and its application is hot and cold water supply.

Simply glue the two pieces together and you now have an adaptor to hook a hose up to your MAG pump (or any other pump that has ½ NPT threading).

There might (most likely) be one more adaptation that you will need for this to fit. If your MAG pump has the threads below the body of the pump, you will have to remove some of the plastic on the adaptor so that it will fit. The threaded portion of the pump is too close to the body of the pump. I used a rasp and just kept going around until it was able to fit past the body of the pump. Here it is hooked up to the pump.

You must have misread my suggestion as it has nothing to do with putting tap water back into the tank but avoiding the use of it at all.

Where I got my info the people use a pump to remove dirty water from the tank then use the pump to refill the tank with aged water or salt treated water. Most pumps speed water changes up without wasting water.


In my case all my tanks are 24+ inches deep with aggressive cichlids that bite so the 10" tube that you get is worthless unless I do it myself since my 9 year old helper doesn't like to be bit. She uses the 24" tube and is very happy and enjoys the time spent with me helping.
