newbs beware

many people claim you need mh but you dont. it is 2nd to best tho ( vho is best)
vho is queen
they run cooler and put out the samww light. i know this will be argued but there is no reason to. mh only look brighter becasue they are a small point source. same with pc they only look brighter.

now who ever arguse this with me needs to have there acount on hold while they do some research.

one reason the myth that mh are needed is that people with pc or vho are trying to save money and end up not doing as much maintance as people with mh who invest alot of cash. and take care of it as they shold.

i cant belive the ignorance the internet allows to spread.

weall love garf right. well they favor vho could it be the y actualy did research.

many epople claim research but really only are going to sales sites. i worked a a lfs and they pushed mh like crazy why be cause it cost more. what did everyone sue on there tanks at home? pc or vho


also vho need replacing every 2 years and can be dimmed.

( forgive typeing in on lap top and its wierd positioned

garf favors vho!

mh is king and vho is queen and we all know the queen is always the ruler

There are many things that cannot be kept under VHOs that can be kept under MH in my experience, and the experiences of many other people who can spell and use proper grammer.

Anyone who joins a board just to start shouting "everything you know is wrong" raises suspicion... are you trying to sell something?

 

[ChrisV]

Whatever dude, I love my metal halides. I like and use vho, pc too, but my preference is mh.

spread is more even on flourescents sure but to be honest slight intensity variations dont bother me...

Besides most of us agree that you can accomplish the same coral growth with different types of lighting and kelvin.

 

[cjsrch]

me sell somthing. i wish. only thing i sell i advertise else where and has nothing to do with lighting.


you state your comment as if what you say is FACT and it isnot. true vho is not good for deep tanks but depth is its only restriction.

anything shallower then 24 inches it is perfect.



and yes sounds like everything that you know IS wrong. where was your research done. what mh setup was that site selling.

 

[cjsrch]

i say that they are the same outputwise except that vho is alot cheeper. how offten do you replace your bulbs?

 

[Jolieve]

Anyone who has read the studies on the difference in par value between VHO lights and Metal Halides would know that what you are saying cjsrch is complete and utter bs.

There are organisms that will not survive under VHO lights. There is a reason that metal halides have the most desired status for lighting tanks with hard corals. That is because these tanks are successful, plain and simple.

[cjsrch]

umm again. what type of mh were these sites selling.


my tank is currently down cause i just moved. i am buying a new 150. i will be using VHO ONLY. youll see the quality of my coral and my electric bill.


i think mh put out like 2 more lux or lums per wat then vho ( long time ago i read this i forget) but the number was sooooo small it isnt even worth it.

 

[ChrisV]

omg, I be you like fluidized bed filters and use a lot of red slime romover..

 

[cjsrch]

FLUIDIZED BED FILTERS on FW yes. and i actualy see no reason for not using them in a reef.
thanks for that. why not? they are great at converting nh3 to no2 to no3.

what you gonna say nitrate factory.... BS it isnt. sure it isnt the compleat cyclle ( anarobic and anoxic) but it certinly dosnt make any extra nitrate

actualy never set my hands on a redslime remover ( or any algae remover )

Note to newbies:

I encourage you to read and research and formulate your own opinions before accepting mine or anyone else's, but most especially this person's who seems to be selling an ancient and outdated form of reefkeeping that reminds one of the stone age, when people thought fire was a pretty neat invention and making tools from rocks was cool.

especialy me... RUDE especialy you. guys do your own reasearch but make sure it is a site hat has nothing to do with sales.
where are some pictsof your MH tank.

vho is not stoneage. there is constant progress with it. always improving it. MH to me seems to be standing still. havent seens any new mh products recently.

fighting an endless battle my friend, just stop.

 

[cjsrch]

i did say that it wouldbe argued didnt i lol

i get a kick out of how some one else opinion becomes fact when you quote it...


just cause some one writes somthing dosnt mean it is true.


here read this "rios are the best pump ever" someonesomewhere



does taht make it true. NOPE

 

[tinyreef]

who's this frickin' guy? is he with anyone here? :?


vho actinic might be superior (imo) to high kelvin mh's (i.e. fluorescing) but the shimmer-effect of mh's are just as aesthetically pleasing (perhaps moreso due to the more "natural" look.

vho's might be better for your wallet, energy, bulbs, and initial costs but if you want better lighting (ability to raise any 'light' coral) people should probably go with mh's (supplemented with vho actinic, but that's just my pers pref :mrgreen: ).

btw, mh's have definitely advanced. the incredible amount of differing kelvin bulbs (e.g. 10000K, 14000K, 20000K, etc.), different sizes (70W, 150W, 1000W, etc.), SE or DE, fixtures, ballasts-types, and pricing levels show mh's are much more agile than vho's.

vho's have stalled. URI and maybe two other also-rans dominate the vho market. (go with uri's :wink: ). to compare the two techs is ludicrious. no contest in advancement, mh-hands down. i think uri's change to offer non-internal reflectors is the biggest change in the last 3~4 years? whoopie.

i don't think hobbyists have an ulterior motives for "pushing" mh's (i don't. buy less of them, more for me on clearance sales days ). people ask which is superior, mh's are usually the answer. which is more affordable, vho/pc are usually the answer. i think cost more than quality unfortunately motives most people/hobbyist initially.

again, i do like vho's. i've been running them for a while. i've also run mh's for a while. i like the mh's more (again, pers pref) but my wallet likes the vho's more. it depends on the individual's priorities.

 

[cjsrch]

ok if you were to take everyhting into consideration. cost and "quality" hate to say it i think vho would come out on top.


ohh find me a dimmable MH ballast as far as i know unless you wanna spend butloads just on the ballast vho is the only one that is contolable.

i know icecap is making a ballast that is dimmable for t5.

 

[Juck]

Wow,, does beaslbob have a brother?

 

[cjsrch]

was taht a joke? explain that comment.

let me guess some guy who was smart and understood lighting

 

[ChrisV]

I think the powerful ripple effect alone would sway most towards MH.

Also a good % of reefers use vho supplements with thier MH, why would you want them to choose one or the other when both have thier qualities?

 

[tinyreef]

cj,
there are loads of pluses and minuses to each side. i'm a vho-guy and i concede that mh's are the better lighting.

vho's are dimmable, ok. mh's can be moveable, i.e. trackable lighting like the sun.

vho-actinics fluoresce better (imo). mh's penetrate deeper and create more noticeable shimmer-effects.

vho bulbs last longer than mh's (before going completely kaput, usability is another issue ime). i.e. don't just slap new all vho's on after running for two years. you will shock your corals. i used to shock them even when i stagger replaced them 50/50. they may light up after a year and a half of running but that don't mean they are still good to go.

you say vho's are the best, ok. but you'd never use them as the sole light source on any tank over 30" deep, right?
i would recommend mh's if you want to spend once for a lighting type. if you are concerned with $$$ then pc/vho might be a better choice and you learn to live without the more "advanced" corals and less "natural" look.

good for the wallet or good for the corals. two different things is all i'm saying. priorities.

 

[cjsrch]

trackabale light... why it dosnt affect anything... stimm penetrates teh same. same streangth on;ly reason taht the sun makes a diff on the ocean as it moves across the sky is the earth ios round. test show no color shifts in vho after 2 years. new ballast are responsiable for that.

but it is a fact that vho can keep the same coral as mh and be jsut as nice. if i want a shimmer ill put in an incandesant bulb or a few leds in the hood.
