My education on the aquarium hobby is improving thanks to the input on this forum. I would now like to add to it by understanding what all you experts test for outside of normal testing. I'll give an overview and start from there.
By normal in my reef tank I test for Amm, Nitrite, Nitrate, pH, Temp, Salinity, Phosphate and Calcium. My 55gal is relatively new (2 months), has about 100lb live rock and a 5-6" LS bed. Thanks to Pasfur my old canister filter is no more and is just additional volume and circulation. I have 2 Oscellaris Clowns that have been in 1 week, 2 cleaner shrimp and about 6-8 hermit crabs. I don't have any coral yet as both time and money dictates my additions.
I perform weekly tests for all the above, 10% water change every week. I only use API test kits and have found them very reliable. I add Kent Marine Purple Up twice per week and have noticed that my corraline algae (Green & Purple) have really increased and improved. I bought this on recommendation to keep calcium and trace elements up.
What other weekly / monthly / regular tests would you recommend be made? There are a lot out there and they can be pricey so I was really looking for guide on a kind of priority level for testing.
Also, based on the extensive expereince what brands and types of supplements do you use for your reef tanks? I've seen the occasional reference on the tank of the month but would like a broader reference.
