Algae requires light to grow. The brown/beige build up on the inside of a pump and any area of decent water flow, usually in a higher oxygen, and lower light environment, is actually the beneficial bacterial cultures that are breaking down the toxic ammonia that comes from fish waste, uneaten food, and decaying organic materials in the tank.

What your seeing is these bacterial cultures. You want them in your tank, as most fish cannot live without them. Basically these guys are flushing the toilet in your tank. You want them to live on a biological filter, which is any large amount of surface area that water flows through, and again, high oxygen, decent water flow, and low light. Once you know where they live, Do Not clean or throw away and replace their home. If you do that, you risk toxic levels of ammonia and nitrite which results in fish disease, parasites, and possibly death.

Google "Biological Filtration in Aquariums" and educate yourself on the process, or stop keeping fish if you don\'t want to do this. Once you learn the information, you don\'t need to put forth any more effort, and your fish live better lives and you succeed with your hobby. Don\'t bother with if if you would rather spend money on more fish, fish medication, and having a bad, depressing experience. Biological filtration is vital to fish.

All of that being said, the interior working parts of your water pumps is not where you want them living. They don\'t really do much harm there, but if you experience a power outage, it is possible for the bacterial cultures to cause the magnetic impeller to seize in the impeller housing when the power comes back on. This can result in the unit melting from excessive heat and then you have to replace the pump.

If you are not over stocking and over feeding, and if you are doing regular partial water changes on a regular basis, then every three months or so, disassemble the water pump when you\'re doing a water change. Use a clean tooth brush with no chemicals on it to clean the cylindrical magnetic impeller, and the impeller housing (the hole the impeller goes in) to remove any build up. Put it back together, and put it back in the tank or where ever it belongs. If it is a powerhead, turn it upside down to get any air out of it, then put it where it goes in the tank. Similarly, removing any air from a canister filter or any other filter will help the pump to start working when it is plugged in.

Is that a fuel pump cut off switch or a crash switch on a 89 chevy berretta

No.. Only Ford does that. The fuel pump will not operate if the alternator is not producing power. That is the cut off. If the engine is not turning the alternator in a crash but the key is on the pump stops. Make sure all 6 diodes inside your alternator are goo. before you go after the fuel pump.

85 mustang fuel pump not primeing

See if the oil pressure switch has 3 prongs. If so and it's leaking oil, that may be the problem. I can't recall what year they stopped doing that switch but my '89 had it. Aside from that, check the fuel pump relay. It can click and still not supply power to the pump.

The petmate pump stopped working so I opened it up. The pump is covered in a brown goo. What is the problem and can it be fixed?

Your membrane has failed. You need to replace the membrane, but you need to sanitize the system first. It would be better to get a whole new system than deal with this.

My van keeps heetin up and pushin water back into the coolant tank

Hi... you are going to have to do some more checking. After the engine is cooled down open the radiator cap, look for goo on the bottom of the cap. Look for oil or goo in the coolant.

What you PROBABLY have is a bad head gasket and the pressure is pushing the coolant out of the engine...

I wish I had better news...

I replaced the thermostat, but it still blows cold air. What gives?

The ford taurus and mercury sable are very well know to have coolant pressure, heat problems. I have worked on a minimum of 300 of these specific vehicles in my career, I can tell you the system is a headache,yet manageable. Are you getting cold air through the vents? is the blower motor working? Is your antifreeze brown in color or goo like? (a tell tale sign of a broken water pump and 90% probability of a clogged heater core.
also other basics, have you flushed the system and checked to make sure the car is not air bound?

Brown goo coming from exhaust pipe on a ford

I would think that the brown goo is most likely to be caused byworn piston rings or valve seals which are allowing unburnt oil to be expelled into the exhaust system. The other thought is that it may be a coolant leak such as a head gasket problem which is allowing steam or water into the engine and then exhaust.

Last cycle water will not emptying

Your pump is more than likely shot!

Defective Lid Switch
Check lid switch for proper operation. Check the switch for continuity. If it is found to be open, replace the switch assembly.
Defective Water Pump
If the motor is running and water is not pumping it could be a defective water pump. Ensure the tub to pump water hose is clear. If so, replace the pump.

Defective Motor
If the motor is not running, the pump will not work. Most washing machine use a reversible motor and it is possible for the machine to agitate and not spin or drain.

Please leave a goo rating
