just finished my 5,000 gallon pond. the problem am having is the bottom river rocks are turning green and the waterfall rock are green too. is there anything I can use to combat this green algae. I live in florida so the water temp is allways about 77. I have uv sterilizer to keep the water clear and I have bio filters running too. see attached photo of what the pond looked before the green algae came in

You might think about getting use to a nice coat of algae it is natural..
It has to grow some were,, in your filter would be best...What kind of filter are you running ? And do you have fish ?
Welcome to the forum....And your new pond looks good !!

right now I have no filter. I just finished a home made filter that is going to be install this weekend, the filter consist of a rubber made tub with a pvc pipe attached to the water fall 4000 GPH pump I cut the hose inserted a pvc T it diverred water into the filter sprays down ward to a filter media under the filter media I have plastic balls to capture the beneficial bacteria, for the bottom water is pushed up to a exit hose that drains into the pond I know green algie is natural but I would like the bottom river rock nice and clean. and right now I only have about 20 small to medium goldfish and koi and 2 oscars

The filter will help once it gets going good
But the rocks on the bottom will end up causing you a lot of problems for your pond down the road

[printman]

what kind of problems

[DrDave]

Unless you have a raging current over those rocks, they will become a septic area for uneaten food and waste from the fish. Most ponders have to learn this the hard way. Rocks in a cascading waterfall and around the perifery are ok.

that makes sense, I guess my solution to this instead of going thru the mess of removing all the rock will be if you see were I have the skimmer it's working with a 1800 GPH pump
I can put a rubber hose in the out flow of the pump and rig a pvc 1/2 pipe with holes in the back of the pond pointing toward the waterfall I guess this will give me a water current going over the rocks so my filter in the other end can catch the waste...you think that will work?.......jorge

[DrDave]

Only you will be able to see if the current is moving debries from the rocks. We can only speculate.

I had river rocks in my first pond, I just put a pressure end on my hose and squirted it out ever so often, it never hurt anything that I could see, and I did like the looks of it. Other than murking up the water at the time that is. When I reworked my pond last time I left out the rock after reading this forum. I still miss the rock but I do need to get in the pond on occasion, because of its size I can't just lean over anymore. It is much easier without the rock.
