I have been looking at CF1200 for my AR620T, I realise this might be a little overkill, but should give me some head room at a later stage for adding some more fish. Problem is, I don't want to modify the stock hood too much, as I'd like to be able to keep the tank saleable at a later stage, if I upgrade. I know some of you guys have modified Aqua One tanks to take external canister filters, but i don't know how you guys have done it. Some advice from those who have would be awesome, Pictures of the jobs might be even better. I was thinking of drilling some suitable sized holes in the back of the hood, where the stock filtration normally sits, and then using the standard holes in the hood to feed the pipe through, so if I do sell this tank and get something bigger at a later stage, all I have to do is patch the holes I made in the hood using some plastic and some silicone sealant.
I have also been looking at a lighting upgrade, as I don't like the yellow light the stock tubes give off. After getting some 6500k/900 lamps for a different tank, I really like the look of that light in the tank, I don't really want to go hacking up the hood of the tank, nor do i want to remove the hood all together, I have found some replacement tubes from HFF, and don't know which one will give the the correct "Bright White" colour in my tank. I have posted the links in the hope someone can inform me. Google was of no help today. In my tank, I have various plants, Ambulia, and some grass like plants, and some red stem type plants,(common LFS stuff), Fish wise, I have 10 Glow lights, and Harlequins, and some guppies, and a couple of bristle noses, i'm soon to have 2x electric blue gourami's as well.
Aqua One PL 18W Marine Blue 14K
Aqua One PL 18W Mix Triphosphor & Biolux
Aqua One PL 18W Mix Triphosphor 7.1K & Blue 14K
Aqua One PL 18W Triphosphor
After reading the stickied thread and some more resources on google, I think the third one, is the standard tubes, and I guessed the 14k one would be the brightest one. Which one would give me the brightest light, but also be good for my plants.
