Changed thanks Did them from memory, so my mistake. Are you sure on the grolux? That seems too high

Here is simple pic which show the difference well. just took a pic of my t5 luminaire. Kelvin rating by andyh_2011, on Flickr As can be easily seen the pink tube is the one with a 4-5k rating the others are 6-8k. I like the versatility of the mutli tube setup as i mix them to give the...

My view is, light is light, kelvin is colour temperature. And within the range you are talking about there is no real difference in plant growth.

Whoa massive debate looming. Me personally 6500 -8000k is best it gives a nice white light and makes greens look vivid. Its what i class as a nice clean white light. Weakness, is the reds, but does this really matter, maybe if you have a shoal of red fish that you want to show the colours off...

i looked a while back and all i could find was crap Chinese imports with very poor build quality. The arcadia one is very good, but as already said not the cheapest.

Hey Stu My dad and Bro are probably better placed to answer the MH question, but in short yes they can explode towards the end of life. Normally 2 yrs based on 7-8 hrs per day. They both have multiple MH setups and have both experienced the BANG!. Normally recommended that you replace them at 2...

if you want white light you should aim for approx 6500k - 8000k tube. I would suggest trying www.lampspecs.co.uk you will find some great tubes at much more reasonable prices

It should be fine, i am now running two tubes on my 90cm/180l no problem at all.

You can buy direct from Arcadia website parts store, excllent service i have used them before. http://arcadia-uk.info/sale.php?mid=48& ... sub=&id=25

define cheaper t5's? If you mean cheaper than the branded powerglo or lifeglo, Approx £20-£25 branded tubes then yes. I buy my tubes from Lampspecs.co.uk and for a 2ft/24w i generally pay between £8 and 12 each As you have seen just done a comparison with them on my nano journal. As...

John IMO If you adding CO2 then no problem dude! i ran two 18w over my 35l with no problem, in fact did consider more at one point p.s Is 60l a nano nowadays? or is this just you trying to suggest, that to a man of your calibre.......this is only a little one! :lol: :lol:

first one!

cant find any ebay any chance you could Pm details? Interesting point about using a lesser ballast, i will look into it :thumbup:

I am trying to source a 75w ish Metal Halide light for one of my scapes. So far i have only been able to find a Giesemann Nova 70w but its £306.95 :jawdrop Any of you chaps know of any others? I can find 75w Metal halide bulbs (arcadia ones) but no light units. Could i fit a 75w bulb in...

Hey Viktor get in touch with Arcadia there after sales and customer service is really good and they will get it sorted for you. They sell all the spares you could want Andy

All sound advice chaps! Thats why UKAPS rocks. Just good to check!

Probably, try contacting Hagen see if u can buy a new lid?

Cheers Dan :thumbup: So no 1 Raise the light and keep an eye on C02 What about nutrients as the plants will be getting more light is it advisable to increase the dosing slowly etc Should i reduce the photo period from say 7 to 6 hrs? will that help? :geek:

Hello My new Metal Halide arrives in a few weeks and want to start to think about the transition from my current lights Arcadia 60cm Luminaire 4 x24w T5 tubes for 7 hours per day. The main reason for the change was the fact that the 6Ocm light was a tempoary fix whilst waiting for Mh to arrive...

Yes i am waiting to take delivery in 4-6weeks an ADA Solar I with NA-Green bulb

Kelvin rating for me is a personel choice, as you can grow plants under most lights no matter the kelvin rating (ask Clive/Ceg4048 to explain that thing about photons/the matrix etc) :geek: I perosnally am going for one around about the 8000k mark as i dont like the colour rendition that the...

Hey, i have just recently had the same debate, i have chosen the MH for my 90cm. In answer to your question will it be enough, yes several members on here alone have had great success with a 150w MH above a 90cm.

18w

I run two 18w lights on my tank which is very similar in size, not because i need too but because i choose too. I like the higher light levels but this then presents extra challenges, more CO2 and more nutrients. I would say start with one light and see how you get on, you can always buy another...

Tom, Interesting what you say about the ballast, as over here in the UK the importer (TGM) leads me to believe they have sourced their own UK specific Ballasts now. I am keen to understand what makes a good ballast as if what you say is true and i dont doubt it for a second, an increase of...

Dan Thanks for the link to this! Great journal especially for somebody considering this light fitting! Just got to sell the wife to pay for it :shh:

In answer t your question, no you wouldn't need two its personal preference, This tank is 20" long (35l) so i decided two suited what i required. Originally i had one mounted centrally on the back pane of the tank. I can measure for you.... leave it with me

Garuf is bang on the supafish lights are really good i am running two 18w on my 35l and the give much nicer light than the arcpods. I.e more greens/white light This is what they look like: Good results with them: everything looks so green!

I agree with all the other comments. I would suggest that the only reason for replacing them is if you aren't happy with the look they give your tank. :thumbup: Andyh

Thanks aaron, will have a look now.

:( Shame! I alwats enjoy reading your stuff, as i have two read it twice :geek: (you use big words) I also like your matrix references!

Clive (Ceg4048) Sorry a little off topic Have you ever produced a journal on your tank, I would love to have a read? I had a quick search but just found loads of your posts to other peoples questions :thumbup:

You could be describing me there! I spend hours drooling over my ADA catalogues dreaming of shiny things! :geek:

Any pictures of it? One thing to remember is that LED lights are more directional than a t5/t8 tube which emits light 360degrees hence the need for reflectors etc. The LED's are very effective at reducing wasted light. My tank in lounge lights the whole room due to the tubes. Sounds promising...

Without sounding weird........"That's one sexy light!" :shh:

So if i deduce correctly the light is only 5cm high. Do you reckon i could stand it on top of a 24 x 12 x12 without the legs if i put some sort of retaining pins in place to stop it dropping in the tank. By the way popped into maidenhead the other week and saw your tank, very impressive. Are...

I have a chance to buy a 4 x 24w t5 (the older version not the OL2 super thin one.) Can anyone tell me the depth of the actual light unit? as i am limited on the size of unit and can accommodate. Also can anyone tell me the total height with the legs on from the rim of the tank to the top of...

Hey Guys and Gals Anybody tell me what type of tubes these are? I am looking to see if i can pick up any higher/alternate spec tubes for my lights its a 18w Aquadistri Pod style light. I can source standard tubes from my local Maidenhead aquatics, but wanted to have a look if anything...
