DIY tank size recomendations

the lights I am planning to use on my 75 are T-5 HO flourescent

Drs Foster and Smith's T-5 bulbs and fixtures.

from the research I did on them I am planning to use just two 4' bulbs on the tank that now seems proverbial in that its allways planned but never done :rolleyes: :cool: :sad :p

they seem to have all the benifits of power compact without the drawbacks, the fewer bulbs than NO, and ballasts used to produce the light seems like it would make for less heat, not to mention their smaller size that makes reflectors for them more eficient-less restrike on the bulb.

they aren't real common yet so finding a way to diy them might be harder, but I thought the difference in electricity to run was a selling point that somewhat made up for the difference in initial cost.

I was planning to make my own parabolic reflectors, I can scan my diagrams in and send them to you if you want, Matak.

hehe the hang glider comment was just for jest but I was trying to make a point to consider unusual ways of dealing with it. :D

it gave me a thought :) after I got done laughing about it...

you could have a board that you put across over the tank between the built ins that you could hang a sling to support some of your wieght on to leave your hands free. would save those close calls leaning way over trying to reach something in the back... might be a chalenge to design your cabnets so it looked normal and still worked with your board when you needed it. and finish that board so it doesn't look to out of place with your nice cabnetry :)

and cleats around the edge of the stool if you are going to need one. wouldn't want you to loose your footing with your weight on the sling if you were up on the stool. those raised edges around the stool would give you an idea of where you are on it as well, so you don't have to be feeling around with your feet to figure it out.

I'd consider two stools. one that is the right hight so you can work in the front of the tank without bending over to much... you don't want to be up to high on this one. and the other one high enough so you have your belly over the top of the tank when you lean over it with the sling support and are reaching for the back of the tank.

make them nestable and a partition of the built in section to put them away when you don't need them would be the ideal arangement.

I currently work at a fibreglass factory and have 30lbs of scrap fibreglass pieces and expect to get about 50lbs more before I go back to my seasonal job in March. Really good quality glass too. My warm weather job involves applying dozens and dozens of gallons of epoxy so I wind up with at least 4 gallons of jug drain drippings alone each season. So my only real cost is plywood & glass.

As for the five foot mark, I want to go bigger than four feet, but I think my wife would be overwelmed with a six footer (she was surprised I wasn't going to build another 3 footer). Besides, my thinking is that a five footer would accomodate 4' long flourescent tubes better than a 4' wide tank, but I could be wrong. Also, customising (read: drilling) a wood/fibreglass tank is much easier.

Cost is a factor, but I will definately look into MH & PC lighting.

Beviking, your and SnakeIces comments are well heeded. I am built comfortably close to the ground so reaching into the tank will be a consideration, and this takes the maintenance issue into consideration as well.

*edit* :laugh: HangGlider eh? Show me the plans! go big or go home
Wow I wish I could get free epoxy!! Did you check to make sure it's water potable? Anyway, with your dimensions, you would need two 8X4 sheets of plywood, correct? If so, you could optimize and make a 6'X3'X2' (LXWXH) out of these two sheets. You would probably be happier in the long run. :dance

Free supplies are always a bonus! You lucky guy!
The initial cost has always kept me with NO lighting. Fewer bulbs with MH & PC lighting may be beneficial to some, but leaves less room to mix and match to your taste. It's been awhile since investigating pros/cons of either and I'm not claiming one superior over the other.
As for the hangglider/sling idea. Put it on a roller bearing track that spans over the tank and over your couch. Might make things go easier convincing your wife if she knows she's you're thinking of her too! ...just think about it :idea2: ;)

I don't think this was mentioned yet, but have you thought about an open tank? When I build my "dream tank" it will be open for sure. Especially since you're building it custom.
Open tank? I'm piqued, go on ..... :idea2:
 
Hey Starry, haven't seen you for awhile, how is U going? Could you explain to me what you mean by 'an open tank'?
 
an open tank is just that, the lights are raised up from the water so the plants can grow out of the water. there are afew water plants we grow that won't flower under normal submersed growth but if they can grow out of the water they will flower.

however there are some draw backs to open tanks. the lighting has to be a little more for the same growth since its farther away. because the tank is open you might loose some fish to carpet surfing. and water loss will be greater, which might not be a bad thing if your house is usually very dry, but moisture problems are a concern.

it is another dimension, that has benifits only for a couple of applications. if you are just going for the underwater garden then I don't think it is to your advantage.
