Filter on Return Pump Necessary???

[benihuma]

I was just wondering if it was necessary to have a filter on my return pump in my sump? Wouldn't it be benneficial for some of the sump critters to be whisked into the main tank? There would be no risk of large things getting into the pump since nothing large can get into my sump. I could just put that little plastic filter thing on. Would small particles getting in the return pump hurt it? Thanks.

HEY BENI....
I HAVE A FEW PUMPS IN MY SUMP AND DO NOT USE
THE PRE-FILTERS THAT ARE SUPPLIED....I ONLY USE
THE LITTLE PLASTIC PIECE INSIDE THE PRE-FILTER SO
NOT TO RISK ONE OF THE PUMPS GETTING STUCK
ONTO THE OTHER DUE TO THE SUCTION ON THE END
OF THE PUMP....
THOSE PRE-FILTERS ARE NOTHING MORE THAN
NITRATE MAGNETS IN MY OPINION ANYHOW.....
NOTHING IS GOING TO HAPPEN TO YOUR PUMP IF THE
PRE-FILTER IS NOT ON IT....

Thanks. I was thinking the same thing in regards to nitrates. I guess I just needed some reassuring.

I get less bubbles in the tank if I have the filter on.

HEY ILIKE....
IF YOU WANT TO REMOVE YOUR PRE-FILTER BUT ARE
RELUCTANT BECAUSE OF THE BUBBLE ISSUE....JUST
ADD A LITTLE MORE WATER TO YOUR SUMP SO THAT
THE PUMP DOESNT SUCK THE WATER AT THE TOP...
JUST MAKE SURE IF YOUR POWER FAILS THAT YOU
DONT HAVE TOO MUCH WATER IN THERE TO OVERFLOW...
YOU CAN DO THIS BY....
FIRST...MARK THE WATER LEVEL WHEN THE PUMP STARTS
RETURNING BUBBLES TO YOUR TANK...
GET A STICKER AND MARK IT "LOWEST WATER LEVEL"
THEN....
1-SHUT OFF ALL YOUR PUMPS
2-WHEN THE SUMP FILLS UP ADD WATER TO THE HIGHEST
LEVEL YOU WANT IT...ABOUT 2 INCHES BELOW THE TOP
OF THE LOWEST HEIGHT OF YOUR SUMP...
3-TURN YOUR PUMPS BACK ON AND WHEN THE WATER
LEVEL EVENS OUT...PLACE A STICKER AT THE WATER LINE
IN THE SUMP AND MARK IT..."HIGHEST WATER LEVEL"
NOW YOU WILL KNOW THAT THIS IS THE HIGHEST WATER
LEVEL YOU CAN FILL YOUR SUMP TO AND ANYTHING IN BETWEEN
THE 2 STICKERS IS ACCEPTABLE FOR NOT RETURNING BUBBLES BACK TO YOUR DISPLAY TANK AND NOW YOU WILL HAVE MORE
ROOM IN YOUR SUMP SHOULD YOU NEED IT...
REGARDS....
