OK, no fighting!

Here's the deal. I would like to have xenias, star polyps, zoos, frogspawn, maybe an anemone. Now, I have read, and have been told by my LFS, that 130W of PC lighting will house these just fine over a 29 gallon DT. They have assured me they will thrive, not just live. I would like some opinions on this. I would love get clams, but that is the only thing I really want that requires the MH. So, I will forgo them, if these will work for what I want.

i think the xenias, polyps, zoos and frogspawn will be fine under that lighting, but the anemone is iffy. The thing about lighting is that the watts aren't a good measurement. Watts just kinda give us a general idea of what the par of the lighting is. This is what really counts. Check this thread out: https://www.saltwaterfish.com/vb/show...light=lighting
amazing information! The thing is that you shouldn't measure what corals you can get with the wattage of lights you have, it just depends on what KIND of lighting you have. so, imo, an anemone won't do well under just pc lighting, no matter the wattage... because it won't produce the par you need to keep it really healthy. You shouldn't get an anemone if it's just going to be "ok" in your lighting. That's not why we're in the hobby. We're meant to give these critters an environment that is most like theirs in the wild, and giving an anemone just pc lighting isn't accomplishing that...

I would think they would be ok. I would like to see a little more wattage for mine. I have always been told 5 to 8 watts per gallon is best.

 

[fgcu14]

I'm not expert by any means however it is my understanding that almost all anenomes and corals will live with 4 watts of light per gal of water. However for clams you need a min. of 8 watts per gal.

ok, so the PC lights listed at 10000k, what does that translate into par?

 

[saltfreak4]

The 65W 10000K lights are not adequate for an anemone, they say that is the suns intesity at the equator. How much more do you need?

i have a flower anenome under pc..4 x 65 wtt...9 months now..alot type and placement..if it doesnt like the light it will move...mine started in sand..now happy high in tank..hasnt moved in months..3 times original purchased size.. in a 75 gal tank

ok, I have read this before and I don't know who this guy is, but he's a little off about the kelvins. The ocean does not look blue because of the higher K light??? Not true it has to do with filtering and light waves that penentrate, what gets through and what doesn't. Now, I don't know what a kelvin rating in bulbs is, but I am looking it up. Wavelength is what makes color, so I until I find out about the kelvins, I am also confused about his blue color statement. you can have an actinic that is 10000k and it is most certainly blue. Again, going to look this stuff up, but this information makes me say HMMMMM????? So, I was wondering if I can find another expert on the subject, but thanks for the post.

if you don't want the opinions of others, why did you post this in the first place? PC lights do not give off the par that a MH light would give. Simple as that. You have to buy a specific device to measure par, and i do not have one. And the 10000k refers to the spectrum that the light delivers... that's all... if that light delivered the sun's intensity at the equator, then why do we have other lighting at all??? Why wouldn't that be sufficient for all corals? it's not because it doesn't. if you don't like the information i have given you, then go ahead and buy the pc lights and the anemone... seems like you were going to do that anyway.

 

[jdragunas]

actinics aren't 10000k... they're at a lower spectrum, like 7100k and that's why they're blue.

well i thought i explained why. I am very much aware that an MH light gives off more par than a PC!!!! No one asked you to measure par of anything! The fact that it gives off the light of the sun is the EXACT reason I am posting!!! I was wondering the same thing!!!! Look if I am going to get slammed by you for posting then just don't respond! No JERK I am not going to buy any anemones!!!! I am simply asking because of the FACT that I have been given the information as I have represented to you! GET OFF MY BACK! And don't dare to assume something that is not FACT!

HMMMM maybe you should go back and read the post yourself, they say the blue in higher in K 6700K is yellow!!!

 

[saltfreak4]

OH and BTW! The frogspawn on the this site states they need a "strong" light. See this is what is confusing, you state yes, frogspawn would be fine under PC and yet what is "strong" lighting????

 

[saltfreak4]

Kelvin: This is the color of the light that the bulb produces. The acceptable range for reef aquariums ranges from 6500K (yellow) to 20,000K (blue). So the lower this number, the more yellow the light, and the higher the number the more blue. Some people use pure 20K bulbs and their tanks often appear rather blue. Others use a 10K bulb which is a crisp white. This is the most important number to pay attention to when deciding on lights because if you buy a bulb outside of the spectrum useable by corals then you are buying a useless bulb. Another thing to keep in mind is that the higher the K rating, the deeper the light will penetrate in to the water. Hence why the ocean looks blue.

wow, someone woke up on the wrong side of the bed...

sorry to wake the beast! hehehe, no offense intended in my post, though...
and i thought this was you asking me to measure in par "ok, so the PC lights listed at 10000k, what does that translate into par?"
and i thought this was you stating that your light would support an anemone "The 65W 10000K lights are not adequate for an anemone, they say that is the suns intesity at the equator. How much more do you need?"

 

[jdragunas]

sorry if i confused your posts, but i'm not a mean person and i didn't mean to come off as it... i should really use more smileys...

 

[saltfreak4]

Didn't wake up on the wrong side of the bed, but I have been investigating this for weeks! I am not dense! I get things quick, I am getting conflicting information, which is why I posted with ok, no fighting! I took light and waves in physics. Kelvin is a measurement of intensity of some sort. Just can't remember. Anyway, I don't think there is any other way to take your post.
"if you don't want the opinions of others, why did you post this in the first place? PC lights do not give off the par that a MH light would give. Simple as that."
I love the opinions of other (s) just need the others not just one, and if you are getting your information from that post, then you aren't helping much. I will ask my journeyman electrician friend. All of the information from here seems to be coming from the same place--a place I find flawed.

 

[saltfreak4]

i guess this is the other thing, if I can get three or four of these under my hood, will that work? Just need more?

 

[rslinger]

I have bta under pc in my
Small tank and it is doing really well also have torch frogspawn and a couple brains all thriving growing and spreading

 

[saltfreak4]

I was thinking if you could get enough light down into the tank, especially if it's a small tank, you could do it. And not that the animals would just live, but do well under the light.
The LFS does have his anemones under PC and they are not doing well, which is why I wondered. Maybe, not enough, maybe just can't be done.
