For the last 3 years I've been maintaining a low tech, heavily planted Rio 180 for a local school, and the time has come for a redesign. Over this period I've been convinced they should never have switched to T5 from T8 lighting! The two bulbs just seem to much in a low tech system, and...

I'm probably getting a 60P soon, and am trying to decide what to light it with. I'm thinking I'll probably use 2 Superfish clip-on lights (budget!), but it's which ones to go for. What would you use? I've never really had a serious planted tank over 25 liters! It will be high tech of course...

Could someone please help me with the length of this light from where it clips to the glass to the tip of the unit? Or better yet a pic of one on a Mini M? Thanks in advance!

Just thought I'd ask if anyone's running low tech under a Juwel twin T5 light system. I'm rather wishing the old T8 unit hadn't died a couple of years back, as I had to replace it with the new T5 one. Is it possible without CO2 injection? I know the old T8 system worked very well for me for...

I'm wondering what light to use over my Do!aqua cube. I have a 9w CF that is currently on the 10l, but I want to make sure I'm not blasting so much light that liquid carbon is not enough. Does anyone have any recommendations or guidance on what I should use? Here's what's sitting in front of me...

Hi all, I bought one of the new-ish AquaEl shrimp kits (the 10 liter) a few days ago, and have been running it with the standard 9w PC bulb that came with it for 10 hours. I am wondering if that's enough for the likes of M. umbrosum, HC and Marsilea that I also have. I also have an Arcadia Arc...

I don't suppose anyone knows where I might be able to find an 18w Compact T5? All I can find really is 24w and above, and apparently Interpet don't do an 18w. George, if you read this didn't you use one for your nano a while back, or was that a 24? Thing is I've got a customer who has one of...

This could sound like a strange question but it could same me a lot of money on bulbs! I bought a cheap 3x24w luminaire ages ago on eBay, but I think the bulbs were crap as they all died quite quickly one after the other. As it was cheap, I need to know if it is a standard size or just some...

I've always been told that turning the lights off for a short time during the photoperiod will reduce the risk of algae, due to the algae not being able to store nutrients as long as plants. But... another arguement I've heared is that this way the lighting is more inconsistant, and algae enjoy...
