For cyber monday, I ordered myself a pretty good light fixture. Looked at a few websites and it seems like Amazon had the best price. Bought the Coralife 08606 Lunar Aqualight High Output T5 Quad Lamp Fixture, 36-Inch light fixture. There have been plans to have a canopy made for the tank and it's still up in the air at the moment.
So I've worked up some plans to build the tank a canopy. I decided to go with a very light wood, pine, and i don't think i need a frame for the canopy because I plan for it to be pretty light in weight. So here are the first few renderings of what I want it to look like.
**The inner bulge is the light so it's not part of the canopy.
This is an x-ray rendering, trying to show the rim support.
Decided over the weekend to finally build the last component, the canopy. This was pretty fun as it was the easiest thing I had to build for this project. No frame, just the shell because I needed it to be light in weight. I just used some angled bracers and screwed them into the wood for support. I used pine as it is light and takes in a wonderful stain as well.
Fitting, without the stain.
Things I still need to do:
1) Seal the whole thing.
2) Let it air dry.
3) Relocate diploma.
4) Decide to either get rid of the glass lid or let it stay...
Came home in the nick of time and saved my canopy from certain destruction as it rained and poured. I was missing 1 thing and that was the pull handle. I went to the local Home Depot and found they are officially out and will never sell that kind of pull handle. I was devastated...I asked if they would like to sell me their display, and they just ripped it out and slapped the regular price on it. Got home, leveled out the handle and installed it and did a test fitting.
Here is how it all turned out.
So happy with the outcome. I just need to get adjusted to the big thing.
Had a talk with a buddy of mine and he pointed out I may need more substrate since it just does look like an inch all around. Thought about getting some eco-complete to just place ontop of the whole thing since the bottom has all that mulm, no need to mix it all up.
I came home last night from work and wanted to check on the light and noticed the heat was unbearable! Apparently leaving the back open is certainly not enough ventilation. So I quickly turned the light off as the light bulb started to pulsate in a strange rhythm. I just about cooked my brand new light. So I turned it off and let it rest the night. Turned the timer off and turned it on in the morning and found no pulsating bulbs, I let out a sigh of relief... So I'm planning on adding some vents to the top of the canopy since the hot air will naturally rise and the light fan is situated at the top and will help expel the hot air out naturally. I also plan to add in two computer fans to create that circulation of air throughout the canopy. So if I add the fans, would I need the vents? I feel like I d since the light fans are so close to the canopy top.
Here's the fan uncovered.
Notice the light fan and how close it is to the canopy ceiling. I think because of the height I should add a vent for natural air exhaust.
Got a chance to go to my LFS and bought a 39w 10k light and also one 6700 39w light to replace the two actinics. I changed them in and glad I got the 6700 bulb. I really need to fix up the overheating issue first. I haven't even thought about planting yet as I need some more substrate. So much more to do...
Today I was able to visit a local computer store and with the help of a friend, a second opinion, I bought a fan for the canopy. My canopy has some space constraints so I am going to try out the fitting for one fan first. I bought the "Enermax 80 mm Case Fan" the specs are as follows:
I did a closer analysis of the specs and realized the CFM was not specified as CFM but m3/h. So I did some calculations and realized its 29 CFM. So given the volume of the canopy it would take about 16 minutes to have pulled out all the heat. This was a good test because the fan was 7.99, an amount I would be willing to sacrifice for the sake of a test. I have another fan in mind; and at least I started small so I can always adjust easier. The fan I saw that will work is 69.69 CFM which will be great. Going to buy two fans, enlarge the inserts and call it a day.
Here are some pics:
Inserted...I know horrible job, hand saw. Wish I had that vibrating saw!!
So it's been over more than an hour since I left my light on with the canopy closed and the fan side is drastically cooler than the other side. If i added the same fan on the other side it would probably bring it down to an ok temp; but still I want a bigger fan circulating air. Temp readings on the side that has no fan reads 107.6 degrees. The side that has a fan has a read of 90 degrees 17.6 degree diff is a pretty substantial finding. The temp without a fan running at all is 135 degrees F. I will invest in the larger fans.
