External filter/pumps

Post  Jacqueline on Sun Sep 25, 2011 8:52 pm

Apart from the obvious, what's the difference between an external and internal filter/pump? Planning an external but as I've never had one before, how do I go about maintaining it? And, what are the benefits? This is an expensive purchase so any advice would be extremely helpful! Cheers J

Pro's

Much more room for media meaning it is much more efficient.

you can add things like carbon or poly pads in for chemical filteration.

Because of the extra surface area in the filter it doesn't need cleaned as often.

Also because it doesn't clog easy your flow doesn't drop off so quick.

You can turn the taps off, remove the hoses and carry the whole filter to the sink without getting anything wet.

More room in the tank without the filter there.

You have more choice with flow using the filter return. Choose between rotating returns, spray bars etc.

You can put equipment inline in the filter hose such as CO2 delivery or heaters.




cons

More expensive innitially

I wouldn't be without one on a tank over 30lt now tbh!

To maintain simply clean the sponges/bio balls etc once every few weeks in only tank water as you would the sponges of an internal.

You will prob find you need to do it alot less often though Smile

yeah there are pipes one going in and one coming out...quite chunky tbh...but can be hidden well with nice backing paper, the bits that go into the tank themselves are about inch round hooks...will pop a pic on in a bit of mine so you can see.x
