Cool stuff man! My pond looks like crap compared to yours. I need to figure out something to do with the sides. Plus the water has massive algea blooms in it right now. You can see a good 6" . I need to do something with it!
mine has the hair algea in it along the sides. and i just net out the floating stuff.if you hsve sn overflow id recommend running the hose in it for about sn hour, does a water change and usually after about 2 or 3 times the green water algae (if thats what u have) will disapear.
My pond kinda looks the same ill have 6 oscars in there in the near future along with am arowana and some Pbass and my 2 clown knives.. feeding them is gona be a btich
it stays pretty warm on its own. plus i have a few heating pads that lay in the bottom if it gets too cold. they only warm up to 85 degrees so it wont hurt the liner and it gives off enough heat to keep the lower part of the poond around 75.
