Reducing Algae in a Pond

Is there anything other than bleach or pool chemicals that I can use in my small garden pond to prevent algae? Last year I used laundry bleach and it killed a frog. I have also caught dogs in the pond on hot days. I don't want anything that will be harmful to animals, etc. I've had to drain and clean the pond twice already this season due to the algae and it's too much work to keep doing it repeatedly. There is a water fountain in the pond that runs from 6 a.m. to 9 p.m.

My mother and grandmother used barley straw to keep their ponds sparkling clear/clean. They both had fishponds that were havens for fish, frogs, birds.
I'm not sure of your budget, but there are plenty of places online to buy it...

Cleaning Algae From a Pond

I moved into a new home and there is a 50 gallon pond in the front yard by front door! It has green algae along the walls. I bought a $50 filter and pump at Lowe's and it doesn't do the job. I have bought stuff to put in the water which also does not seem to help. I went to a pond nursery and ended up buying a PF 300 filter and am going to try to hook it up with the little pump I got at Lowe's. This filter cost me $150.

The pond is oval and has 2 shelves on either side with a deep center. I feel I am going round in circles to keep clean. Or do I have to! I have no fish as of yet, just one plant, (variegated Japanese iris). Do I need a filter of this magnitude or should I keep pouring in the chemicals (algae killers)?

Putting some barley straw in a flow through bag will help keep the pond clean. It will not clean the pond, but if you put it in there after you clean it, it will help keep it clean. I"m not talking about using a huge amount, just a small handful in a bag should do the trick. I read about this on the Gardener's supply website.

If I use shock for a pool and chlorine to reduce the algae, would it be safe to use these items in my water pond if I do not plan on adding fish or plants for a month?
