Hi, A while back on one of my former setups I had some Blue LED's that were tied into the central lighting unit. They came on an hour before the normal lights went off and illuminated the tank which was supposed to mimic 'moon' light. I haven't seen people mention this much on the forums and...

Really appreciate the assist Danny, but I think you might have misread my post. The bulbs I have are 15mm.... so guess that makes them T5's. Can I plug T8's into a T5 unit? I think I read somewhere that the Juwel light units are a little odd...... not sure if anyone can confirm

Thanks for the replies guys. I think I might have a larger problem. I have removed one of the bulbs and it appears to be 900mm pin to pin. The T5's on Lampspecs site measure 849mm. Any ideas on what I bulbs I can use? Am I able to use T8's or will I have the wrong unit for that? I really...

As suspected............. I got way to much light :) thanks for posting though

Thanks..... Is the HI/HO all about the bulb or about the fitting too? I only ask as I am wondering if I can replace the current HO bulbs with bulbs that are not HO? ie.... will the unit allow for it?

....... and I'm guessing there is no easy way to measure PAR? Given that wpg is used as a rough guideline, how should I measure the amount of light I need to order and whether or not that light should have/needs a reflector? Also.... is HI/HO more powerful than a standard T5? and if so, how do...

Also... how should T5 'HiLites' be measured? Are these considered to be stronger than their equivalent wattage counterparts? I am about to order some bulbs from Lampspecs and really need an idea of what i should be looking at. Given the size of my setup, I think I need the 849mm length and in...

Hey, After reading a reply in a thread that I am subscribed to it prompted a question (that was unrelated to the thread). I have just built a Walstad style tank and am worrying a little about the light I have in the tank. I currently have 2x45w T5 HiLite and a RIO 180 tank. Thus I have around...

Thanks again chaps! Chris, it was your journal, that I read on thursday last week, that inspired the hairgrass idea. I have put a post in the general thread, but it has no replies about the idea too. I think I may follow your idea of waiting until it pops to do something about it. I have...

Thanks, In the shop we thought they were the T8's and he was telling me that I would have problems growing Glosso, Dwarf Hairgrass and a few other fern type plants I was looking at. Given that it is a T5, would I be okay with those plants? What I am trying to create is a dwarf grass front, 3...

Well..... that does infact bring me to my next question.... I popped into a London shops listed on this website somewhere and was chatting with the chap in there. He was showing me a Juwell 180 tank that he had set up and its very similar, minus a far parts, to what I want to do..... heavy on...

Thanks for the replies. Are blue led's good for periods before and after?

Morning all, I have a Juwell 180 Rio tank with its standard lighting. I am about to renew my efforts into maintaining the tank and I wanted to know if I am better off having my lights on for two sets of 4hrs which are broken by a 5 hour gap, or am I better off having a one times 4hr period? I...

I am not at home right now, but is it easy to change/remove the existing ones? The Juwel Tubes for all sizes of Juwel Aquariums! We offer a bright Day-Lite and a warm Warm-Lite tube! Install the Warm-Lite in the front and the Day-Lite at the back of your Multilux or Duolux light unit for...

I had read in numerous places that tubs start to weaken after 9 months. Needless to say, this is supported by the shops that sell them too 8O) The other reason is that plants that have traditional grown well and bushy/thick/dense in my tank are now begining to show the same type of growth a...

hi, thanks for the very quick response. I have just measured them and they are roughly 1.5cms or 0.6(ish)" i guess. Does that make them T5's? Are those better than T*8's? Lee

Hi all, First post here! I have to say that I am very impressed with this website. I have found that I am equally keen to get my plants looking good as I am my fish..... Firstly..... A little about my tank RIO 180 - still with standard kit. Sand substrate with plant tabs placed at...
