Our neighbours have given us a big (looks like 60L) tank and stand complete with gravel, sand, ornaments and filter. I've given it a good wash in hot water (no detergents or anything) and am washing the gravel seperately. Is there anything else I need to do to it? I understand I need to set it up then leave it a few weeks to make sure the water is ready. We are going to get cold water fish, was thinking gold fish but from reading on here the tank won't be big enough.
Thanks
