| one thing you might want to consider, spring is a vulnerable time for the health of your koi. By disturbing water quality with a thourough cleansing you may be creating more negative than good. Did you know that 10 % of a biofilter is located on the walls of your pond alone? Even tho you replace the good bugs with starter ones, it's not the bio diversity you already had and now your waiting for over a month for things to begin returning to something akin to normal. Water quality is the key should you discover issues with the health of your koi. Guard your bio filter that you have been running 24/7 this past year so that you don't loose that part of your protection. |
