I decided to go ahead tonight and get a bunch of numbers. I've been on straight IO instead of Reef Crystals for quite a a while now and the numbers show. I did like the Cal./Alk/Mag numbers from RC but didn't like all the organics that were included in there. This made my skimmer go nuts right after a water change and always had an increase in cyano right after a water change. Plus, I don't know if sitting in a storage container for a month by the time I got to making more water helped any of that at all.
So, here's the numbers of the tank taken right before and after lights out.
Salt mix: Instant Ocean
Salinity: 34ppt (just calibrated refractometer)
Temp: 80.1F (Hanna handheld probe)
pH: 7.94 (Hanna handheld probe)
ORP: 160 (ditto)
Nitrate: a light 5 (API)
p04: 0.20 (Hanna Checker) I was expecting much higher here but I guess this is why I don't have so much cyano right now.
Calcium: 380 (API)
Alk: 11dKH (API)
Mag: 1170 (Salifert)
Numbers are pretty much right inline with IO. I plan on getting a galaxia pretty soon and with the past couple new additions I think I'm ready to start doing some dosing! This will be a first which I've been strangely looking forward to since the beginning. I've been reading up on it all and with the numbers I have and the inhabitants I've got and getting I believe it's time.
I've got a 7gallon bucket under the stand I use for ATO with an aqualifter controlled by three float switches. The Lowest shuts it off when the water level dropped suddenly for things like a water change or for some reason the tank is drained by some other (hopefully never) reason. The middle float is the main float that controls it and the top float is a failsafe to the middle float. The aqualifter inside the bucket is connected to a spare skimmer's silencer thing-a-ma-jig with a little sponge filter inside of that. It is suspended and never hits the bottom.
I plan on a very simple procedure. Dump in the lime (a bag of Mrs. Wages from the store) and mix it up with a maxijet 1200 and then let it set all day to settle down. I fill up the ATO bucket once a week with about 5g of fresh ro/di water. I'll start making sure to get that done in the morning so I can stir it up again and let it sit all day. From my very precise calculations of gestimation I should be good for at least a month before needing to add any more lime and need to dump in another bag. I'm not to worried about being precise and will want fully saturated lime to bring the calcium levels up a little and then maintain.
I think I'd like to be around 420. This should also help bring up my pH which also always been low just below 8. I'd like to see that get to and maintain above 8. My mag is pretty good but I could probably get away with dosing just a little magnesium once a week during the weekly kalk stirring. I'd like to get that back up to around 1200-1300 and stay there.
I'll try that out for a month or so and get some more readings.
