For Goldfish and Koi Pond owners, now is the time when we are yearning for crystal clear waters and big fat fish greedily surfacing for handouts.
'Patience' is the operative word here. The best rule of thumb for spring time is avoid feeding and serious pond cleaning until your water lily pads turn green. Fish
that have been hibernating all winter need time to warm up thoroughly and get their digestive systems tuned upbefore they can safely resume their piggy summer eating habits.
In spring time, koi and goldfish immune systems are at their lowest point of the year. So, let those sleepy and groggy fishies lie. Avoid any activity that results in you
stirring them into a frenzy just to catch and temporarily relocate them.
Until your pond water reaches a consistent 45 degrees....
Don't net them
Don't drain their water
Don't stir up their water
Don't add new fish
Don't fret if you have a fringe of string algae growing on the walls of the pond. This is the best spring tonic for your
fish. You can keep this in check later as the pond warms up.
Do re-start your pump and bio-filter when water temperatures reach 45 degrees
Do a partial water change of 30% after the water temperature is above 45 degrees
Do add a biological starter to your water
Do add a sludge removing product if you have more than 1/2 inch of 'pudding' looking sludge on the bottom
Do gently remove leaves that remain in the bottom of the pond
Do add barley straw now to retard excess algae growth later when the water warms up.
