I posted this in another forum also. Looking for advise on upgrading from a 90g to a 180g. the last time I upgraded from a 90g to a 240g I just made up more salt water and moved everything to the 180g and everything worked out fine. This time I want to replace all the rock with dead rock islands that have been bleached and acid cleaned. I would probabally put a rock or 2 from existing tank in for seeding and mix up the balance of salt water. The first tank upgrade worked well but used existing rock work with some additional added.The reason for not using the old rock is phosphate leaching. I want to do the right thing on this upgrade so any and all opinions and experience are appreciated.
Thanks,
Doug
