6x2x2 nd aquatics tank and stand full set up

Anyone got a decent size tank they don’t want or going cheap plz

So the pond is filling up at the moment, and I’m going to leave it like this for two weeks or so. So I need a PH kit is there anything else I need before putting koi or gold fish in the pond

Want this but need to get the tank dialed in first

I have about 6 of them now need a couple of new tanks
