Controlling algae in new pond
I'm hoping this is the right place for this. Was referred from Reddit.
I'm going to spend some time this weekend building a semi raised pond. 500 gallon. 8ft w x 5ft l x 2ft d.
In my previous iteration, I was using a 4ft x 4ft pond liner as a bowl with a mini fountain pump in it. I could drain it and fill it with fresh water on Friday and it'd be turning green by Sunday.
In an effort to avoid that this time, I'm trying to figure out what I need to do. At first, youtube identified nitrifying bacteria as something I could use to keep the water clean and clear. That lead to ammonia as an option and ultimately plants, which will eat the algae's food, thus preventing algae growth.
So now I'm trying to figure out how many plants my pond would need to successfully stay relatively algae free.
My plan as well is to drain the pond every fall, so these would be plants that I can hopefully get from a store or successfully bring indoors yearly.
My preferred plants are lilypads and hyacinth. Open from there.
Thanks for the help!
