I did my first round of real water testing for my tank tonight. I still have to add more liverock and another pump for better circulation before I start adding corals, but I would like to start preparing for how I am going to have to treat the water. Here are the results:
ph: 8.2
Ammonia: 0 ppm
Nitrite: 0 ppm
Nitrate: 0 ppm (?, this seems strange to me)
Calcium: 340 ppm
Carbonate Hardness: 9
Phosphate: 0.5 ppm
The reason I have measurable phosphates is because when I first filled the tank I didn't have my RO system yet and I used regular tap water treated with prime. I am doing water changes every few days with RO water treated with Instant Ocean to slowly bring that down.
I know my calcium isn't quite high enough for corals yet. I'm hoping someone will tell me the best way to get my calcium levels above 400. You could get good result's with Brightwell Aquatic's 2 part calcium and alkalinity additive if you wanna spend some cash get a calcium reactor.
Is it ok that I have no readable nitrates?? That's fine. I'm almost positive the tank is cycled because I have had all that rock and a fish in there for a few weeks now. I'm hoping my skimmer is just doing a great job or maybe there is something on my liverock that eats up nitrates?? most likely a bit of both the more you wait to add anything to the tank the better in the long run.
Right now the only additive I am using is Instant Ocean into my RO water. What other additives will I need? A Ph buffer and 2-part calcium and alkalinity additive and your fine and switch to Instant Ocean Reef Crystal's better for reef tank's. What kind of schedule should I keep with those additives? use buffer when you do a water change and add top off water and the 2-part every other day. Is that dependant on my water change schedule?? no
