uh oh..white moldy stuff in pond? dead fish...
hi all..last week I saw a couple of my goldfish dead in the ice on my pond. Well, now the ice is melting and I was able to get them out, and I noticed white moldy looking stuff in the string algae on the sides of the pond. It's very white, as white as snow..what the heck is it? I am thinking it contributed to the death of my goldfish. I thought they would survive the winter being the pond is 3' at its deepest. I was nervous this being my pond's first winter, and had brought in my 1 Koi in late fall..now I am so glad I did. I wanted to keep the pump running all winter in the middle of the pond, kinda like a fountain affect to keep somewhat of a hole open for the fish, but DH wouldnt go for it, or a heater, or a bubbler..now I have dead fishies :(
OK, yeah, I am partly blaming him, lol.
I am also thinking that now I will have to completely empty and clean the whole pond come spring due to this weird white stuff.
Am I right in thinking I will have to completely empty & clean it? Any clues as to what it is? I hope my frogs are alive!!
O, I do have submerged plants in there if it matters..waterlilies, thalia dealbata, & yellow water iris. Also left some watercress floating, which amazingly stayed alive and well thru quite a few freezes..till the whole pond froze up for the first extended time a few weeks ago.
I can't believe the string algae is still alive..and really multiplied (?) over the winter..it amazes me how much of it there is. Poor fishies probably had no oxygen. I feel terrible I killed them.
