Sorry, didn't see that. I would question 360 in a tank with one frag. I would at least test the tank and a fresh batch of SW separately.
Thank guys this is great stuff. I almost pulled the trigger on a reactor tonight but my boss discouraged it. He recommended phoslock or phosgaurd.Reactor with Rowaphos or Phosban would be best for the long term. Rowa in a filter bag (one provided in the bottle) will work too. You can buy bulk GFO (grannualr ferric oxide) from www.bulkreefsupply.com. Polyfilter (that is the brand name) pad is very effective at removing PO4 as well but it is expensive to use and it really needs to be in some sort of filter where the pad can be cut to fit and water is forced through it.
Phosgaurd:Never heard of phosguard or phoslock. Also, what is biomax? Some kind of ceramic media? The pot scrubbies are probably going to be an issue sooner or later.
pH changes throughout the day. Beuffering it will do little to nothing if your alkanlinity is low. You should test your Mg and alkalinity in conjunction with your Ca. What is your specific gravity at and how are you measuring it (hydrometer or refractometer?)?
What should I dump the bio max and scrubbies for? My lighting schedule is not set in stone yet but has been pretty regular.Yeah I'd dump the biomax and scrubbies. Assuming your on a regular lighting schedule best to try to do ph tests around the same time.
RSP calcium levels aren't bad. With what you got in the tank I'm kind of surprised it would get so low if your doing weekly w/c's.
