What to do when getting a 2nd hand tank/tub

1) air pump is necessary.

2) I practiced collecting 10% as seed for new green water. The rest is replaced. Just watch the temp difference.

Will greenwater turns bad during the rainning season with little bright sunshine, or they will survive even on days with cloudy weather?

bro Thiam,
i had just bought a 5ft x 3ft fibre tub...
putting at my parents hse backyard...
going to cultivate greenwater and keep ranchu....
i had also drilled a hole near the top for the water to overflow in case it rains....

here are my doubts and questions:

1)is airpump really neccessary??

2)weekly how much water should i change?

I heard fibre tub tends to leak under hot sun, not very sure how true but my friend's outdoor tub kept leaking. Maybe be more careful.

hmmm... my fiber tub has been out in the open rain or shine for 8 years... and still no problems... maybe he bought a defective one?

hehehe...my 2nd hand fibre tub got 3 small holes....
i patch up with silicone and body fibre and now...its perfect!
