Hello

Im new to the forum and I have a question or two if someone can help me please.

I have a 2400 gallon pond and I planted some oxygenators earlier this spring and they seem to be dying off. I placed 12 bunches of Anarachis and 12 Hornworts.

The Anarachis is turning yellow with very little new growth and the Horntwort is green, but hasnt grown at all.

Anythoughts about what might be causing this? I would like to plant some more, but if these are not growing, I dont want to waste my money until I can correct the problem.

I have 6 Hardy Lillies that are all doing well, so Im not a total loss as a water gardener yet! :)

I've tested the water, and our PH is 8.0 -8.5 (I will be buying a digital meter, I cant seem to match those colors with these old eyes anymore)

KH of 100 - 120

Any help would be greatly appreciated

Thank you

JC

The pH is a bit high. Plants like a more neutral range but that alone should not account for the die off. I've found that often when new submerged plants are added, they at first die back (especially anarcharis) and then will start to grow (in my case only where the fish can't reach them). The plants have suffered shock from going from where they were growing to a store and then to your pond all with different water parameters, lighting, and temperatures. If the fish aren't picking on the plants, then they should start to grow if the pond's water chemistry is okay. I would give them a growing season to recover before saying they can't make it. How close are they to the surface? If planted too deep, they may not do as well. I used to pot mine but because the fish always tear them up anyway (even in plant protectors), I now let the submerged plants float free. The portions that grow at the surface grow the best.

Thank you for the help

They are currently 2 1/2 to 3 feet deep, I will move them towords the shallow end of the pond and see what happens

Thanks again for the help
