Hi Michael. My daughter just moved to the Bay area. She is working for a tech company and they keep her very busy! I agree with all the comments above. Your list looks okay but, don't add more fish because there is too much bioload already and that is what is causing the excess nutrients and green water. Also just remove easy to get at debris like floating leaves. I wouldn't stir up the bottom a lot until your pond has cycled. Basically you have a brand new pond because of all the cleaning. Sit back, relax and have a beer and next year it will look much better! You might have green water for a month or more. There is nothing you can do about it and the more you try to fix it the worse off your pond will be. The chemicals you add really don't help much and sometimes they hurt. I have had a pond 10 years and never have added chemicals except for declor. You need to cut way down on feeding and try to eliminate excess nutrients and add plants to utilize any nitrates that are produced by the nitrogen cycle. I would recommend that you read up on how and why ponds get cycled. Basically you are creating an ecosystem that utilizes all the fish waste and breaks it down to less harmful elements. Once your pond has cycled the green water will instantly go away. Also you definitely need to add an aerator. If the fish are gasping for air it's a sure sign there is low dissolved O2 in your pond.... unless you added non chlorinated water then you are dealing with fish with damaged gills but the same problem that they can't breathe properly. Good luck!
thank you so much for the reply and reassurance. This forum has been awesome. I am going to summarize all the suggestions:
1. sit back, relax, enjoy the pond and allow it to cycle. it should clear with time.
2. add more plants and thin out the stalks of penny wort.
3. don't add more fish or feed the fish - I don't feed the fish and there are only ~20 tiny gold fish in there now. Far cry from the original fish that died after i took over.
4. no more chemicals or cleaning.
5. be diligent removing organic material - leaves etc
6. I turned the iogen to 1, considering removing it.
7. consider adding an aerator - the fish aren't gasping anymore. That was previously when the pond was sick
8. consider creating a bog - im not sure what that is and how to do it. I will try that if above items don't yield results.
last questions:
1. would installing a UV light filter system help improve water quality? I would like to avoid this as it will be a big undertaking?
thank you all for your input. I should have signed on last year when i bought the house and maybe the fish would still be alive.
