What I like about using algae instead is that exactly. It's never going to get any one nutrient too low for the corals. I do add Fe for the algae only.

I do believe that different algae prefer...

If I was to bump Ca up by 100 ppm, my snails and clams will spawn. IMO that's a sign of stress. But to the addition, not elevated CA. I don't know how high it would have would be to cause stress, but...

Does the Ca sink, or stay at the top ?

I do actually pour the salt back and fourth a few times to mix it. I don't like the covers you have to hit with a hammer, so I use an older one. But I'm not...

To the best we can ask for. In reality, if we had this triple checked at different labs around the world, people would still not believe it. We test with hobby kits, the same ones we rely on to keep...

gnikoli,

The discrepency here is far greater than the test kit error. Our kit's are not all off by 100 ppm. Our refractometers are not all off by 25%. We've been through this already.

SPStoner
I have to agree. Look at E.B.'s salt study. I've heard more than a few times lately of people switching to RC to get rid of cyano. The study was basically worthless, yet people do things...

I hear ya, however for the extra $2.50, I'll take the extra Calcium and Magnesium. Sure adding more is not that hard, but if you don't have to do it, that a small price to pay.

I personally don't mind all the waste from the micro fauna. I probably have more particulates in my water than most. I have the filter feedes to show for it. Polycheate worms must number in the tens...

I got 1270 ppm. But I also noticed that my kit is now expired, so I can't say much about those numbers. But I'd know if my reef was low in Mg, and it's not, so I would tend to agree with the kit. I'm...

I agree. LOL

Your Magnesium test got me thinking though. I jut tested my tank, and I got 1330 or so ppm with Salifert. Kind of makes me not want to waste a test on the new salt water, but I think...

I dose it all at once as well. IMO if you're not dosing large amounts, that's fine. How much are you adding to how much water ?

I guess it would be as simple as testing for P from the start of a new tank. It would be interesting to see what would happen in a test with two tanks. That would tell us if the GFO is faster than...

The GFO only removes the P that's in the water. The algae that's growing on the liverock can get it there. There are many cases where there is very little P in the water, yet the algae continues to...

Because Phosphate and other bad things binds to aragonite sand. How much that will matter, I don't know. But it would be a fresh start.
