purple up

[rrobbieboy]

hi, my tanks has bin up and running for month and 2weeks,, just wondering when can i add purple up...

 

[jcs11236]

never.. let it "purple up" naturally

 

[rrobbieboy]

ok thanks... does the water need any additives..

 

[Imbarrie]

Salt and maybe two part.

You don't want to add anything you are not testing for.

If your keeping a reef tank, you will have to monitor your Calcium, Alkalinity and Magnesium for starters. Keeping your mag around 1350 will help the coraline to grow and "purple up" your rocks.

the guy at the store said since my tank is new, i dont need to add the three above you said.... is this true....

most stores really dont know crap either. you need those 3 test kits because you will need to monitor those 3 and dose accordingly, did he reccomend the purple up ? if so does he know what all it contains ? stick to using 2 part and magnesium and water changes, you really probably wont need to dose yet but you can check all levels few hours after you do a water change, then check them all again right before you do the next water change to have a idea of what the up take is on your system and as you start to add corals and coraline starts to grow those up takes will increase

When your numbers are right, get some coraline scrapings from someone.
