might be stating the obvious, but make sure you've measured the diameter of the hole including the thread!!, as thats the width of the bolts you'll need!.....5mm seems pretty small to me. But hope it sorts you out :thumbup:

Find the diameter of the holes...I think they will be around 6-8mm...then look for m6 or m8 nylon bolts on ebay...I use them for holding wings on my RC aircraft!!!.....I may even have a few spare if you let me know the diameter. They generally are long but can easily be cut to length if you...

Yes but with the compact fluorescent in the aqua one luminaire only occupies half the width of the fitting, as you said: Any stem plants I've had either end taller than half the height of the aquarium have bent inwards towards the light giving a very cone like appearance, and the tank looked...

That is an excellent site :thumbup: . I've been using spiral daylight bulbs above my dart frog vivs for a few years and they've cost me a lot more than that!!!....Think I'll be buying a good few off them, I like the fact that they do two part compact spirals that allow you to just change the...

After taking on board everyones advice I went for this unit: http://cgi.ebay.co.uk/ws/eBayISAPI.dll? ... K:MEWNX:IT Got the unit 24 hours after ordering it. and after asking about it, had tubes suitable for freshwater/plant growth fitted too totally chuffed with it, a much better spread of...

Thanks again for the replies, the lighting unit thats already on the aquarium gives me just under 2 wpg, but with being a compact fluorescent the light is mainly concentrated in the middle, with a noticable drop of in light levels at either end. What T5 units do other people use? If it comes to...

Thanks for the info, I'll have pressurised CO2 installed in the next week or two, but was just trying to make up my mind between the two units I mentioned. I think I'll go for the eqj trading luminaire as I know what the quality of the units are like, and I can always turn off unneeded tubes if...

Thanks for the reply, and yeah thats whats got me wondering....unless its somehow a sealed unit I cant see how its got irreplaceable ballasts? But I've never heard anyone complain about too much light as opposed to not enough?, after all I suppose its easy enough to turn one or two lamps off...

I'm slowly upgrading my first attempt at a planted tank as I go along, getting into them after a pretty long time growing plants in hydroponic nft sytems, next on the list is lighting. The tank is an Aqua one Horizon 60l jobby, and comes equipped with a 24w power compact type bulb so could do...

It does sound like that could be the fault, the problem with duff bulbs and holders, is they sometimes cause the ignitor to continually try to fire up the bulb and burns them out if the problem isn't corrected. Changing the bulb holder would be my first choice, but make sure you can get hold of...

Dont want to sound like I'm teaching granny to suck eggs but are you sure the bulb is making good contact with the bulb electrical contacts?? Failing that it sounds lke the ignitor may have gone, normally a pretty easy fix IF you know your way around lighting systems HQI bulbs are metal...
