Shallow spring fed pond- Weeds, waterfall pump, and aeration?

[mikeysp]

Hi, my dad has a ~30ft diameter, 3ft deep, spring fed pond (several gallons per minute).

We are going to make a floating platform for a pump I have and pump it onto the cave rocks over the spring source for an aesthetic spot for him to relax.

Problem: the pond grows weeds (see pic) and I figured the pump will get clogged in short order, atleast in summer months.

The waterfall pump will only run when he is enjoying it, so I would not be able to use that pump for an additional work of water agitation (if that would even help).

So, I thought about a small pong aerator in the 15000 gallon pond range to run from midnight to 6AM in the warm months.

I am unsure how to proceed and would be grateful for any advice.

Thank you. -Mike

PS. To pre-empt any question as to the white balls: they are some solar led inflatables that he put in for decor.

The pump I am using is a Tsurumi Hs3.75s-62. It is a Manual Electric Submersible trash pump. 1HP & 3-inch discharge. Designed to pump sand, solids and debris with minimal wear and clogging.

Crickets?...I measured water flow yesterday and it is 17 Gallons Per Minute. Little help. Please.

I wonder if you could set it on rocks or bricks on the bottom. Some here have mentioned they tie a rope on for easy retrieval. Hopefully others more knowledgeable than I will chime in.

A trash pump is a good choice still no guarantee it won't clog up . I myself would get like 12 aquablocks to make a large pre-filter to keep out the big stuff and fish. Or like a water tote from tractor supply then place it upside down over the pump
