Todays Q & A Of The Day comes from Susan who writes, “HELP! I think my filter is to small for my pond. I have a Laguna 2100 bio filter. My pond is in full sun it’s 23ft.long 20ft.wide and 3ft.deep. My pond is 3yrs. old and my water is still green and my ph is to high. I have used all kinds of chem.and solar salt. Nothing has changed. I can’t believe my koi are still happy and alive! Can you help?”
Answer: Thank you Susan for your question. Fish can certainly handle green water and if the pH is around 9.0 or below you’re probably ok there as well.
