Well it's the end of the weekend now, so perhaps you have already done it all, but here goes anyway.
Heaters:
Tricky, my tank came with a single 300W heater, so that is what I use, but there are arguments for using say 2 lower powered heaters too...
- One heater at each end of the aquarium should distribute the heat more evenly.
- If a heater thermostat goes faulty in the 'ON' state, it should take less time for a 150W heater (based on you having 2 x 150W heaters) to boil your fish than it would for a 300W heater to do the same thing.
You do have to jiggle around with twin heaters though, and try to balance them, as just setting the thermostats the same may not be enough, and you'll find one heater is on a lot, and the other one is bearly ever switching on.
Personally, I've found the lower power heaters are a similar cost to the higher power ones, so for the sake of cash I would just buy a single heater, but then I check my tank temps most days too...
Gravel Vac:
Couldn't find the tape measure handy, so figured it would be easier with a picture![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
This is my gravel vac hanging inside my spare Regency 120 tank for purposes of scale. The clear one is the one I use on the Aqua One tank, ignore the green one, I use that on my 60L tank.
I think as long as the main tube is completely under the water the total size is up to you, I just found I didn't really want one with a 'mouth' any bigger than this one so that I could negotiate the plants and ornaments, and also I didn't want one any taller than this as then I think it would start getting a bit awkward trying to feed it and the hose around the strengthening braces at the top of the tank.
Lighting:
Do your T8 tubes have metal reflectors clipped onto them? If not then that would be my first recommendation as that will help to 'throw' more light at the water.
Again it is a tricky subject... I had the T8 hood, but due to it leaking I contact Aqua One for a replacement, and pursuaded them to send me a T5 hood![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
The T5 do penetrate the water deeper, and are brighter, but the T8's were not dark by any means, and if you are not going for live plants then the T8's will work in your favour by not giving the algea so much light to thrive on![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
What you might want to do is get a couple of replacement T8 tubes though, as the brightness can fade quite a bit over just a couple of years. I wouldn't bother getting Aqua One tubes in particular though, (unless you choose to), any of the correct length should fit fine![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
I hope all your floor levelling etc went well. Now waiting for the next installment!![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
