Awesome set-up. Thanks for the insight into filtration set-up for the pond. I will doing something similar this dry season. Though i still have some time on my current set-up. Hmmm, the real test will come when the dry season comes around. I hope this year's dry season is not as cold as last year one. But your paima looks quite large to weather low temp.
Aha, so i am not the only one that feeds gars eels ^^ though not so frequent for me anymore, cos any escaped eels tend to block my submersible pumps.
So what are the sizes of all your beasties after four months?
