How to get rid of cloudy water

[Snaz]

Water conditioners and other additives are a huge waste for the new reefer. The markup on a bottle of basically nothing is huge and the LFS pushes them for obvious reasons, it's where they make their real money.

Unless your pulling water from the Tar Sands I would not bother with conditioners. Buffers and additives are meant for established tanks. Dosing a new tank will only result in weird test results and in worse case crashed tanks.

And like everyone else has rightly said... Go slow.
