10 foot round concrete pond - CAN'T KEEP MOLD OUT - how to filter?

Does anyone know the best way to keep this huge concrete fountain/pond clean? It's probably over 200 gallons of water and the pump is housed OUTSIDE of the pond in it's own container of water that is level and drilled through the side of the fountain (so you don't see it in the pond). This fountain is outside and gets really dirty, and the hand held vacuums are too little and way too much work! Any ideas would be great! Thx

Welcome to the forum.
Is the water treated?

Outdoor water features are a lot of work. Keeping the water crystal clear with fish is even more work. Basically a outdoor fountain is a swimming pool. It needs the sides scrubbed, the bottom vacuumed, filter cleaned and chemicals added. A good, properly sized filtration system helps reduce the workload a lot.

The water is treated with pool acid, but I don't have any filter at all in it. That is the dilemma, because the pump is outside of the fountain in it's own container. What kind/brand/type of filter can I use that would clean the water in the fountain? Is there one that can float around in the fountain and pick up the debris? Thanks for the help! k

I would chlorinate the water and regular pool types should work. You can use a granular type that you add at regular intervals or a slow dissolving tablets that you can toss in or put in floating dispensers. All of which are available at any pool store or WalMart. Pick up a simple chlorine test kit while you are there. With it you will be able to tell when you've added enough chlorine.

Pool acid (Muratic/hydrochloric) is used to balance the ph of the water but does nothing to sanitize or help keep algae and other things from growing in the water.
