plainrt Posted July 26, 2015 Author Share Posted July 26, 2015 Iphone5 lol. I'm not saying that is a bad thing, necessarily, just something you gotta take into account. Lol I like that info there. Dang jerks at Ati with misleading info. But yeah I could care less if shorter lifespan 2 Quote Link to comment
Lawnman Posted July 26, 2015 Share Posted July 26, 2015 Some of other acans and dendros still growing. Not too bad for tank with a few sps.What don't you have in this tank? I just spotted a toadstool. 2 Quote Link to comment
plainrt Posted July 26, 2015 Author Share Posted July 26, 2015 Ummmmm hmmmmm I'm not sure. It's too the point there nothing I really want. Oh wait I'm still waiting to find really nice hammer or torch. That damn neon toadstool is from where I cut off large one when I changed up tank from softy tank to what it is now. 1 Quote Link to comment
Rehype Posted July 26, 2015 Share Posted July 26, 2015 According to Sylvania, the manufacturer of ATI lamps, dimming is NOT recommended and does significantly shorten phosphor lifespan. ATI, KZ, etc can say all they want about how it doesn't affect the phosphor life, but they do not manufacture the lamps. Dimming will significantly shorten the lifespan when the bulbs are NOT burned in properly. The burn in period allows the phosphors and mercury to properly distribute throughout the tube (dimming the bulbs prematurely will disrupt this process and result in shorter phosphor lifespan). When following this method on my old dimmable sunpower my bulbs ran their intended cycle which I was able to confirm with a PAR meter. If the bulbs had been affected negatively I would have measured significantly lower PAR values during that period and would have likely had to replace them after 3-4 months. 1 Quote Link to comment

I have checked my bulbs before and didn't notice anything crazy. I'll get meter more often and check them. I think some of mine are like 7 months old now. Gotta look at dates on them someday.

Felicia Posted July 26, 2015 Share Posted July 26, 2015 LOVE these two photos! All the different colors and textures from the different SPS corals in the first picture are just awesome! Beautiful fish! 2 Quote Link to comment

PAR is not the determining factor of lamp replacement, it is the phosphor degradation, it takes many more months than most replace at (12 months) for there to be a noticeable change in output. Each strike literally burns phosphor off of the cathode, and dimming the lamps somehow increases this regardless of the number of strikes previous to the dimming, even using a proper programmed start ballast. Unfortunately I can't find my email from Sylvania explaining it, they did a much better job than I did. 1 Quote Link to comment
plainrt Posted July 26, 2015 Author Share Posted July 26, 2015 Thanks. Long nose Hawks are great fish IMO. I love that side view but it's hard to get decent pics of it. Those two turned out ok. I love when local reefers see my tank in person cause the colors always tend to wow them. I had family stop over yesterday that runs t5s over their own tank and they said they have never seen colors like my tank. To hear that from people that aren't new to the hobby made my day. 3 Quote Link to comment

MikeTR Posted July 26, 2015 Share Posted July 26, 2015 good god man.. nice tank. where the hell have i been.. shiz is amazing gaaah just watched the video... i need some pointers.. 2 Quote Link to comment
plainrt Posted July 26, 2015 Author Share Posted July 26, 2015 good god man.. nice tank. where the hell have i been.. shiz is amazing Lmao thanks. I think not being one of cool kids here it gets overlooked. Or it just sucks. One of the two lol Looking at your tank really makes me miss the option of having big fish. That's what I love about big tanks. 1 Quote Link to comment
ninjamyst Posted July 26, 2015 Share Posted July 26, 2015 do you run a top on this tank? 1 Quote Link to comment
plainrt Posted July 26, 2015 Author Share Posted July 26, 2015 do you run a top on this tank? I do run a screen top. My clowns jump a lot and the yellow wrasse tends to time to time. Other day he bounced off my head and landed back in tank lol.Frame is painted silver so doesn't look so horrible on rimless. When I'm sitting around just watching tank I'll keep top off. 1 Quote Link to comment

DIY screen top? also, does the tank come with the back blacked out or did you add that yourself? sorry for all the noob questions but you and steensj have inspired me to start a similar build in the near future =) 1 Quote Link to comment

Unfortunately I can't find my email from Sylvania explaining it, they did a much better job than I did. Thats true but a typical sign of phosphor degradation is a noticeable shift in spectrum (typically towards the blue end) I personally never witnessed this shift when using this fixture and I doubt any reefer who replaces their bulbs every 6-8 months ever would. 2 Quote Link to comment

I painted the back with krylon fusion. Great tanks for the little money. And no problem with ?s. I'm glad to help if I can. 1 Quote Link to comment

I'm glad to help if I can. cool. i may make mine into a peninsula tank so it's good to know the back doesn't come painted. it's so hard to find pics of this tank. if you know of other build threads besides steensjs and ngh, let me know =).

Right, and that is the typical change point when dimming, otherwise can put about 9-12 months on them. 1 Quote Link to comment
