I see the comment that "filters reduce flow by about 45%." Does this mean a separate filter is not required/recommended for this pump?

If all you want to do is move water, as in a water fall you wouldn't need a filter. I have a filter on the out put end of my pump and it pushes the water right on through it, then one at the top of the falls and it still moves a very impressive amount of water. I don't see how you could put a filter in front of it, anyway. Take a look at the shape in the picture.

A filter is required after the pump if you want to clear the water. If you are sizing a waterfall/weir, etc to drop the water back into the pond, remember to account for the flow loss from the downstream filter. I use a waterfall designed to operate at ~half of the pump's stated flowrate and it is working great.

No - a separate filter is not "required." For years we used the pump with no filter and had a great pond but you will have a much nicer cleaner and clearer pond with one. We built our own filter system and it works great. Search online for "jiffy DIY pond filter" for info on building your own. Also you should buy some "good bacteria" (available on Amazon) to start the natural process to break down waste. "But NO - you do not have to have a filter system to use the pump."

You need a filter. The pump has slits for the water to enter it, but it is not a true filter.

They are talking about in-line filters. And yes you should use a filter in front of the intake.

It does not really have a filter. It sits underwater in my pond & pumps water/debris to an external above ground filter system. It works great!

I think their is enough biological included, I squeezed all that came with it into bottem two trays and then filled to top tray with Matrix. This worked but I found that 'low flow' warning come on. After a month I reduced the amount in all trays and found the flow rate had been resolved. Great filter so far the only think that is not working is the flow rate chart. I just wish it gave real flow volumes rather than percentages.

I used 1 1/4" tube with the included pump and it has large flow. The filter doesn't hinder flow much if kept level with water. Extreme elevation will slow the flow. (Over 10 feet) check for blocks. Check the pump by itself

from the way I understand it you need 3 or 4X the flow per hour so 3X75=225 and times 4 is still only 300 gallons an hour. so it should be more than enough for filtering your tank. Now if you want more flow just add a powerhead and direct it in tha direction you need.

Depending on the installation, there is a filter between the tank and the water supply. The instructions note that you should check this filter if you have diminished flow.

No I purchased a separate inline filter for it, the unit is great better than one we purchased through our R/O vendor.

I would be more concerned with sizing the pond pump to correspond with the maiximum capability of the filter. You need to make sure that the maximum flow will not exceed the limits of the filter.

Flow restrictor is usually built in to the water filter. It is required to restrict the flow. Otherwise the RO filter won't have enough pressure to filter water

We've never tried without filter, but it should work just fine without it. Hope this helps.

I just put a piece of blue tape with the install date on the filter and replace in a year or if the flow slows appreciably (which in my usage/experience takes > 1 year). The filters have gotten more expensive - I used to get them for $70-80 so now I wait longer to replace :)

There are no filters as this is a sump type pump. The pump, however, is a solids handling pump and does well with an out of the pond filter. I use mine with a Laguna filter and the combo works well! This pump is a powerful pump for the money. Mine has been going 24/7 for 3 years now. Larry

Sorry can't really help as my setup is small - 30lit tank. I use my Maxi-Jet inside the tank to filter my tank water. It's not the best setup but after spending Au$100+ I'm determined to use the pump for something.

No other filter is needed, you may want to get some air stones just to keep the water at the bottom of the tank moving though.

The only guideline I can recommend is watch the flow rate. When it slows down, replace the filter.

Take the filter out and run the pump without it. if the pressure seems right it is the filter. I always clean mine as soon as I take them out but they do start to get clogged after a while. Make sure you clean good between the folds in the filter!

Seems like it's faulty to me. I just replaced my filter with a new one and the flow is the same as the one that came with the unit.

I find the question hard to understand.The intake is through the slotted sides. That way the water passes through the filter, through the pump and out.
