It hadn’t cleared appreciably, and new green algae started growing. Arrgh!f<\/p>\n
This is where I put on my water chemistry hat and bite the bullet and get the (fairly expensive) phosphate remover. Or, as we say in the marine reef biz, don’t bother getting a test for phosphate. If you’ve got algae growth, you’ve got excessive phosphate and no ordinary test will show it, because it’s bound up in the algae.<\/p>\n
So we killed off a megadose of algae, and here is bright green new algae within 12 hours. Speed of regrowth tells you something.<\/p>\n
So rather than have this nastiness (nothing likes phosphate except plants: it’s not good for any motile creature) endlessly looping through the system, I bit the bullet, as aforesaid, and poured one more dose into the pond, which immediately turned it milky bluegreen.<\/p>\n
The fish, however don’t seem to mind it, and are running around in it, which is better than they were doing in response to the other stuff, which I think must have stung, or stunk, badly.<\/p>\n
This is not a case of filtering it out, but chemically wiping it out, as best I gather: in the marine hobby we use ferrous oxide granules, but this freshwater stuff is a liquid. And here’s hoping.<\/p>\n
Jane opined a rabbitfish would be a great help in the pond with the algae situation, and then caught herself and grinned, and said: “I don’t suppose it would be very good for the rabbitfish.” Naturally no saltwater creature can work in there. \ud83d\ude09<\/p>\n
We’ve had to top off so much because of leaks in the waterfall (now fixed) and we’ve had overflow, and then that huge influx of rainwater, and with a high phosphate level in our local water, well, it’s not a great surprise. So next year we get some water hyacinth (messy things) and hope to do a natural uptake, but it’s late in the season for that.<\/p>\n
Here’s hoping.<\/p>\n","protected":false},"excerpt":{"rendered":"
