+1 Same here - Lets see emI get my frag on Tuesday...for those that already got it...POST A PIC ALREADY!
Yes. It shouldn't make a difference since we are working on percent difference anyway.
I've been giving some thought to how we should measure the frags and I think I've come up with a decent method. The issue was that a graduated cylinder would be accurate, but wouldn't be large enough to hold the frag. A beaker would be large enough to hold the frag, but doesn't have enough markings to give you a precise enough measurement of the water displacement. With this method, you can use any size container to hold the frag, but will only need to purchase a graduated cylinder.
- First, you will need some sort of container that can hold the coral frag. Ideally, it would be around the same size as the frag and as narrow as possible.
- Next, fill the container with water to the top.
- Pour the water into a graduated cylinder and record the initial amount. I'm not sure what size we need yet, but I'm guessing around a 200 ml. I'll find out once I get my frag.
- Again, fill the container to the top with water (be sure to use water from your aquarium!) and place in the frag. Do this in a place where it won't matter when water spills out of the top.
- Pour the remaining water back into the graduated cylinder and record the amount. The difference between step 3 and step 5 is the amount of water displaced by the coral frag, i.e., the size of the frag.
- Each time you measure the frag, repeat steps 1-5. This way you can change the size of the container if the frag grows to large for the initial container (or you lose it) without affecting the results.
What do you all think?

I think it would work great for the intial testing but what about down the road when the frag isnt really a frag anymore and attached to the LR?
This sounds about right to me. I believe I get the displacement method. Makes sense. Just wondering if said size container will be big enough as the coral gets larger. Anyhow I think we are on the right path here
Got my 1000 ml beaker yesterday. Shoul be good for the displacement testing.
Opening 4.5 inches 6.75 inches tall. Should work.Do you have a link to it? I haven't seen one with the resolution we would need.
Thanks,
CJ

And CJ, what do you mean by resolution? Same as increments? I think the 1000 mL beaker, most of them 50 mL increments. I dunno though, not familiar with these things.
