The first stages of diatoms ::
Cool progression.
I'm sure it will be even more cool when we see the tank as it is today
That is a bummer. It looked enormous. How long did you have it?
BTW, it's really tough to make out your trapezoidal overflow box. It blends in with the back well. Looks good.
I really like the center oveflow makes life easy when Aquascaping. When in wave mode it is very quite. The only thing I don't like about it is they did a glass overflow and skinned it with Acrylic so the water hits the top of the glass and splashes just a bit. Easy enough to fix but one more thing to add to the list. I also modded it to rasie the water level But the glass overflow came in handy there. I made a overflow comb that is taller than the original and sits the inner glass overflow. The cover I made to block out light and contain salt spray from the overflow holds the modded overflow comb in place.
I had the clam for 6yrs. It was on borrowed time. When I received it the box looked like it had rolled down the highway at 70MPH. There wasn't a drop of water left, but the Clam was closed tight. So I acclimated it any way in a seperate bucket, pretty much just filed it up with tank water and a tossed the clam. I was really surprised when it opened.
So you can get a feel for the size of it this as a 5-6" in crocea in the foreground.
