Hi! I installed my ponds two weeks ago and things are still settling down. I have an upper pond which is 7' round and a lower pond which is 18' x 11'. A small 6 foot stream runs between them. A lot of dirt got into the pond during the construction of the rock walls and turned the water brown. It wasn't clearing up, so my local pond expert informed me about how plants will help clear the water up so I put in 8 water lillies, 15 water water hyacinths and 50 anacharis.
I have also started the biofilters with doses of bacteria and while things are improving, now I am concerned that the anacharis are totally covered in silt and I am wondering if that will kill them? Don't they need sunlight and doesn't the silt block them from getting sunlight? Do I need to go in there and "shake" them off?
Your pond installer should have pumped out the dirty water before he collected his final check. So now, here's the best way I know to solve your problem.
Take the plants out, wash them off. Pump out the water, clean the rocks with a strong stream of water, wet vac the silt out and start over.
Be sure you add dechlor before you put your fish back in and I would add bacteria to your biofilter to jump start it.
I wish that you could just grab the anacharis, shake it and wash it off, but the silt will come off the moment you try to pick up the anacharis.
I know you wanted a different answer and I'm sorry you have to clean up your installer's mess. He really should return and do it for free. State law says he has to guarantee his work for a year.
Spring has arrived even if it's not very warm where you live. Check your pond equipment. Is your pump working well?
It's always fun to browse in the spitter and statuary section as well.
