Large fish tanks

Need a pond hoover badddd 😂

Can anyone recommend a mains powered outdoor koi pond feeder please. Got 20 small koi and going away for a week. A neighbour will refill if necessary. TIA.

Wanted bare 4 foot fish tanks no lids or equipment needed. Willing to trade for guppy trios or pairs, fry and juvis max value for the tank would be £50 in the trade. Close as possible to fraserburgh willing to go as far as dundee

Would anyone have a 50 litre + tank and filter they no longer want going free in Bracknell area?
