430gal., L-shaped display

BTW, it looks like it might happen again tonight. If I can stay up--did I mention that I was tired?--I will try to catch some eggs.

From about 10 min. ago.

Thanks! I always do some noise reduction and some sharpening and then I sometimes set the white and black point and lighten or darken the image in the curves box. My algae is starting to disintegrate now, though, so the water column is full of specks of algae flotsam. She's displaying to her reflection in the glass and she's right next to it, so anything that's on the glass shows up in the photo, too, so I spent some time bandaiding and cloning out all the little specks. Not anything major.

They spent some time displaying at the same time as last night, but the spawn didn't come off. I had turned the top closed-loop off so I could try to collect eggs, so that might have thrown them. Or, the chromis were gathered around looking for a meal. Or, as might be most likely, the female might just not have been ready again tonight. Try again tomorrow.
 
Here are photos of a sixline wrasse egg, an hour or so old!!!

To give you a sense of scale, I took a photo of millimeter marks on a ruler at 4x:

Thanks! It gets a little boring after a while though. :) "Okay, looks like glass except for the oil drop. Yep, still an oil drop." Amazing though that something could grow out of that.
 
Waterproofing

Waterproofing

Andy,
I tried to find an old post regarding waterproofing of your wet room
and couldn't find any mention of it. Did you use anything on the floor or
walls. Any ehhaust or fresh air intake?

Thanks,
Ken
 
Hey Ken!

Yeah, I used the concrete sealer stuff for garage floors on the floor. Everything except the outside wall (old stone wall left bare so we could see if there were any drainage issues) was blown in with the closed cell foam insulation. In addition, the crew painted spar varnish on any exposed wood. Nasty stuff. The floor drain is there to make sure there's no standing water. The door is exterior grade. I have an AC unit with a control for the fish room. It blows cold air in but doesn't draw from the room. And, there's an exhaust unit with a humidistat to blow air out. The room is as close to as sealed off from the rest of the house as I could make it.

Plus, we're in Colorado, which is about as dry a climate as you can get without getting crazy and moving to Arizona or something. (I'm kidding. I like Arizona. :) )
 
Wet room

Wet room

Thanks Andy,
So just the typical garage floor paint, not a 2 part epoxy?
How about the ceiling? The walls of the room I am working on are poured concrete so I guess the whole room can get the same treatment. The ceiling will be the weakest link.
Thanks
 
It's the Behr stuff that you can't get at Home Depot (which is where I got it). It's a two part with some kind of stuff you add in for traction. It's supposed to repel even stuff like engine oil once it's dry. You certainly don't want to get salt water on bare concrete. It's pretty porous and I've heard that saltwater will rust the rebar right out from the middle of the concrete.

As far as the ceiling goes, I know that they insulated it really well with the spray stuff. Then drywall, paint, and I think they spar varnished right over top of that. My builder is really paranoid, but he doesn't want to come back to replace the floor joists ten years down the line.

Awesome stuff, especially the pictures of the sixline egg.

You probably said this somewhere, but how many spawning pairs of fish do you have (currently)? I'm only in high school right now, but some day, I wish I could have a set up like yours!
 
Thanks! I had a new one tonight, but managed to dehydrate the egg. :(

I don't know that I've ever counted the species that are spawning in this system. Let's see:

Orchid dottyback
Harlequin filefish
Cleaner wrasse
Sixline wrasse
Green mandarin
Banggai cardinalfish

Plus, I watched one royal gramma follow another one into a hole a couple of days ago, so I strongly suspect that they are going, too.

So, six species or seven if you count the gramma.

Good luck getting yourself set up! High school was about the time I got interested in SW tanks because a buddy of mine's father was a hobbyist. I think he had to mix his own salt back then. I didn't started my own tank until years and years later, but I always remembered how magical I thought that system was. Pretty awful by todays standards--bleached decor and fish quickly or more quickly dying--but still.
 
I might have a little booze in me (muy pequena) but those eggs might be ridiculously neat. Really. People like you expand my world. And the whole time travel thing, you should start selling tickets (really, just slip em a roofie, they'll believe whatever you tell em in the morning). :-D
 
Well, thank you. What's your poison of choice? Mine used to be tequila but I seem to have moved more to gin these days. If you ever have a hankering for good gin, Hendrick's would be my recommendation. :) Mmmm. Good stuff.

Now if I could just get the dang clownfish to spawn. I've never had a single pair spawn for me. I have a couple of really pretty pairs right now, so maybe this'll be the year.
