Tek T5 setup, how many bulbs??

Oh, to the guy who started the thread...

A TX5 unit puts out more par than either of the two units you are looking at (much better reflector design). If you still decide to go with Tek unit look at some of the threads that retrofit fans to them, they need them. Also be sure to use the shield as the reflectors that come with the tek units are prone to pitting/staining.

If you are curious, I use the icecap retro kit... my tank is in wall so I don't need a pretty fixture.
 
For a 75 I would say 6 bulbs at the minimum, 8 bulb is ideal. 4 is only going to give you just over 200 watts. It's not going to give off much light over that tank.

I keep SPS in my 75 with four bulbs without too much issue.

The only matter that offends me, is your ignorance with heat issues. I am still waiting for all your knowledge on the extreme heat a Tek fixture generates. The past posts stated without the use of a shield. Of couse you don't provide any information. Two owners have stated no real heat increase without the use of a shield. I think thats some good input.

"I know enough to know that Sunlight Supply doesnt like to cover warranty issues so you better take care of those TEK reflectors." Since you do not own one, how would know?? You read internet posts to make your assumptions?

As far as Aquactinics, it looks like a good product. It's $160.00 more than a Tek. If I did not get my Tek for free, I would have considered it. I have had zero problems with my Tek and has preformed well. It sounds like you have some underlying feeling about Sunlight Supply. I suggest using a product before stating how inferior they are. You just lose so much creditabilty with your statements.

Do you own a tank, or just read up on them??


Do you comprehend what you read? Where did I say that the drop in PAR was an issue WITHOUT THE SHIELD IN USE? Nowhere did I write that. That's you trying to put words in my mouth, so to speak. I CLEARLY stated, more than once, that the drop in par was signifigant WHEN USING THE SHIELD. THIS IS A FACT. It has been measured, it is a known issue by anyone who has done some reasearch on the product. The heat build up with the shield in use is extreme to the extent that it is high enough to cause a signifigant drop in PAR from the T5's.

The heat and drop in PAR is NOT an issue with the Shield OFF, I NEVER said it was. The problem with not using the shield is stained reflectors, I went on to state that running without the shield, the TEK reflectors are susceptible to staining from salt spray and splash. They have to be cleaned regularly. Again, THIS IS A KNOWN ISSUE!
I stated that the Aquactinics reflectors are the better reflector. Again, THIS IS FACT!

I stated that Sunlight Supply is notorious for not honoring warranty claims. Again, a know fact. Let alone the Customers, It got so bad that dealers of their products were dropping them because of their lack of support. If you had done any reasearch you would know this.

You state that I have no credibility but everything I have written is absolutely correct in regard to the TEK reflectors. Your loyalty to the product is great, but that doesnt make what I have written untrue. It is accurate and factual information. Somebody else in this thread calls me Ignorant, and again, everything I have stated here is true and accurate.
Check yourselves gentleman, you are both taking shots at somebody who has provided accurate, honest, truthful information in regard to the TEK fixture.

First I am accused of pimping for Aquactinics. Now I am accused of having some type of underlying feeling about sunlight supply.
Again, I must ask, do you comprehend what you read?
As I stated already, I own two Blue Wave ballasts, two Lumenmax 3 reflectors and 2 wiring harnesses ... all from Sunlight Supply. I havent had an issue with any of them. I bought them knowing that if I did have problems with them, Sunlight Supply would likely be no help in terms of covering them under warranty.

Oh yeah, I forgot ... I also cannot possibly own a tank because I am more informed than you are about a product.

By the way ... I guess that in both your opinions Barjam is ignorant, has no credibility and also has something against Sunlight Supply as he has the same information as I do on the TEK fixtures. Also, he cannot possibly own a tank. LMAO !!!

Thanks Barjam for chiming in. I really love being called ignorant and lacking credibility (and a tank too) for offering real, valid, accurate information. Unbelievable. Thanks for the back up.
 
Wow...this is pretty sad. All I saw was people discussing light fixtures, then all of a sudden someone took someones comments to seriously. Lighten up a little, we can all have a discussion, without throwing jabs. I think it is great to hear people with experiences with the products we are talking about. If you own the product and you can tell us what you think, that helps me out alot.

Please read my posts. I never took any "shots" at you. I merely stated what my results were as a owner of this fixture. When I purchased my fixture a few years ago, Sunlight Supply was at the forefront of adapting T5 technology for the aquarium hobby. When I purchased it, the Tek was the best thing around (aside from Metal Halide). I did not ever say that it was best fixture out there, I just disagreed with the extreme heat issue.

Unfortuanetly, Tek fixtures went the way of the Remora. People raved and raved about them, but things get better as we progress. Doesn't mean they are junk. I have had excellent results with mine.

What is truely sad about your need to lay out the truth is that none of us answered this guys question as we debated what fixture is better. THis guy had to post a new thread asking the same question (which I provided my insight on the bulbs which I'm sure you would gladly dispute). I am no longer going to entertain this.

By the way ... I guess that in both your opinions Barjam is ignorant

Never called any one ingnorant

I like the arrangement of the tx5 fixture. parabolic type arrangement. I went with 6 bulbs using the tek 2 reflectors because they are three inches wide instead of 2 1/2" of the icecaps. I had a pain in the but time trying to fit it in my canopy but it can be done. my bulb arrangement is as follows from front to back. D&D blue plus 65k GE 3k GE 2 ati blue plus and 1 uvl super atinic. arrangement of bulbs depends on what colors you wanna highlight in your corals. I run my bulbs on icecap 660 and 430. hope that information helps. I got my gear from reefgeek. Paid about 500 bucks for all of it. Good luck and enjoy the hobby. Kurt.

Thought id add some more stuff. I keep a packed stoney tank. not sure about heat issues but i run 2x4" fans.
 
I never called the fixture Junk. I stated that there were lots of reefers with beautiful tanks using these fixtures, if not in this thread, then in another. All of my comments were relative, comparing the TEK to the Aquactinics and why the Aquactinics was a better fixture in many, important regards. Again, what I posted was factual and written without any motives outside of offering information that I know to be accurate.

But when I am posting facts and I am being called out for pimping the product I state is better, called biased against Sunlight Supply, told I dont know what I am talking about, Told that I lack credibility, Told that I can't offer accurate info without personally owning the products ... etc., etc.. I'm not going to stick my head in the sand and go away when I know what I posted is accurate.

I think I added very relevant input to help the OP until it got lost in the shuffle after my motives and information was called into question. Recommending the TX5 answers the bulb quantity part of the question. I'm sorry that I am not one to let it go when I am trying to help and then taken to task for my input but I do tend to defend myself.

I apologize to the OP that it happened in his thread. I hope you find what you are looking for.
 
I have the TEK 48" ( 8x54watt ) system on a 100gal full blown reef ( SPS/LPS/ZOOS/PALYS/SOFTIES ) all are doing well, tank temp stays at 79-81 without fans even on HOTTTT days here in california. Am I happy with it, yes. NUFF SAID.

I never accused you of anything, nor did I call you names or question your credibility. You lumped me in with everything when all I did was offer my own personal experience with the product. I did not think that was fair, nor did I appreciate that.

If you ever want to get about a 25% increase in light performance, hook a fan up to the fixture. A poorly cooled T5 fixture like the Tek isn't going to introduce much more heat to the tank than a well cooled fixture.

If the air right at your bulb is above (or below) 95 degrees, you are losing par. In the 120+ (or 80) degree range you can even see the decrease in lumens (our perception of how bright the lights are).

On top of all that bulbs that are too hot have a shorter life. Are the ends of your bulbs darkened inside? They should not be.
 
Nope.

To be honest.. I'm not a PAR freak like most people are here ( not to be condesending ), but as long as the appearance looks sweet, the corals are growing well, and look good too.. I don't pay attention much to PAR.

Jayke, I dont remember posting anyones name so I am not sure how specifically I lumped you in. I dont think I quoted you in any reply.
You edited your posts so I cannot go back and read exactly what you wrote but I will take your word that there was nothing else but what I write below ...
While you did not use the word "credibility", you did claim that since I did not own either fixture that I did not qualify to offer accurate input. That was the essence of what you wrote and that seems to be a pretty clear questioning of my credibility.

So, I also feel that the implication that I cannot apply reasoning from gathering information from research, basic technical assessment, common sense, other peoples experiences ... to provide accurate and credible information without having to have owned both fixtures is not fair.
Nevertheless, I apologize if you feel that I treated you unfairly as well.

I am not a par freak either, but the prospect of using 216 watts to get similar output to 324 watts on top of longer bulb life appeals greatly to me. To each their own!
 
Weird.
Theres some good info being thrown around, but it almost seems to me that people are getting 'offended' at someone saying a negative comment about a brand of fixture. Thats pretty lame.
Kinda like when Yankees/Red Sox fans go at each others throats cause they like one team or the other, though neither actually PLAYS for the team.
If someone says something negative about something, WGAS? Do your own thing if thats what you like.
Everyone calm down. Have a beer. Look at your tank. Have another beer. :o)

...thats what Im gonna go do.
 
yup 2 each 2 his/her own.

I'm not running a 100k aquarium system, this is just a hobby to me. As long as corals are doing great, show good color, propegating... I don't worry much.. maybe if I paid a couple grand for a sfiligoi or something like that and it aint performing to what is said then I'll worry deeply, but if I only paid 300-400 for a complete light system that dosn't heat up my tank compared to a metal halide system.. then I don't care much. ( I do, but really don't let it consume me ) You get what you paid for.
