Hello all - I'm reviving my fish pond after shutting it down a few years ago. While away on vacation, the power went out for two days and all my fish died. Also, my electricity bill was astronomically high, even though I used a small 60 watt pump. Now I'd like to ask members what they think of the Aquascape aeration kit https://www.amazon.com/gp/product/B0078LTKM8/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1 Is this only for additional aeration or would it be enough?
