220 Gallon Reef Build in the Caribbean...

No the closed top (screw top) bucket/container to the right of the tank shows you have dogs. LOL

Granted I have cats (feline) and I have the same type only smaller size, they are very resourceful. LOL
 
Wow... I feel dumb... thought he was talking about the reflection in the canopy shot...

It's all good. While living in th Caribbean does present some challenges (Ive lived overseas and in Grenada), there're also nunmerous advantages. You've got all the water you need for your tank and water changes. I'd only use RODI water for make up water. That's what I do. How hot does your house get? You might be able to get by with fans. Having local live stock in your tank is going to be very cool. I'm assuming hard corals are prohibited. If you're not keeping them, you wont need much for lighting. Personally, I'd go low tech. Water changes can do wonders.
 
Canopy is basically done. The only thing left is to install the lights (when I get them), route out some channels for the cables on the MP60s (when I get them) and install some sort of ventilation. I have a 10" 120v fan from when I repaired an old ice maker. I'm thinking if I wire this up to a u-ground plug (with an inline fuse) then the apex can control it, it's quiet and low-draw. I'm trying to figure out if the apex temperature probe will work out of water. i don't see why it wouldn't. I have a few spots for extra temp probes on my apex and I may use it to help regulate the temp in the canopy.

Sorry, but I think it is humidity, not temperature, that you should be measuring, both in the canopy and the sump. You would do better to vent this out of doors than into your living space. You don't want to end up with mold problems in your house.

Anywhere else in the world I would agree. Here the humidity is always 70-80% and the house is actually naturally aspirated. The windows are always open (bug screens applied of course) so the air is continually changing. We have to keep damp-rid in all of the closets and change it regularly to prevent our clothes from getting mouldy. I intend on running a cross-breeze through the canopy with an active fan on the intake and an unrestricted output. The heat levels from all of those LEDs should serve to keep the temp high enough to regularly activate the fan, and even without it, the one vent still helps to equalise somewhat with the outside air. The building is reinforced concrete so we won't be knocking any holes in the wall for vents. There is however a big open window within 10 feet of the tank.
 
None taken. I am wholly ignorant about conditions where you are and didn't think about it before writing my previous comment.

Is it really 70-80% RH? I couldn't take that for very long. 45% RH is about my top limit. :)

You would not do good down south-east in US or Central America then.

Ohhh they have no snow either (snicker snicker)
 
I have a snow squall coming down out of the northwest over the Great Lakes hammering my front windows even as we speak. Local RH is 25%.

I've only been as far south as Raleigh, NC a few times on business. That was plenty humid for me. I remember seeing giant fans on the golf courses trying to dry the fairways off as I drove in from the airport. That seems like going a bit overboard on the humidity, thx. I'll stay with what I'm acclimatized for.

The fans make the water wick off the green. I guess because of the humidity it does not evaporate.

I am pretty sure if I was up there and I took a cup of boiling water and tossed it into the air it would evaporate before it hit the ground. In Raleigh... it would hit the ground and continue boiling.
 
Well... I'm on a tiny island surrounded by water with sun and heat year round... today's humidity is 79% and it's RELATIVELY chilly here. http://www.wunderground.com/global/VG.html Should be interesting to see how this will effect my evaporation rates. I would imagine that a higher ambient humidity should bring down the evaporation rate. I do remember it took quite a while for that last .5mm of water to evaporate after I emptied the tank. RODI water is the least of my problems. I produce 58 gal/hr on the boat, just trying to figure out how much room I want to give up for a reservoir in my stand.
 
Just got an email from Salty Supply. They have been awesome. Should be shipping out a pallet worth of stuff in two weeks or so!
