View Full Version : 31" Deep Tank

04-25-2010, 03:00 PM
So ... wife and I are putting in an offer on a bigger house today ... if we get it, I will have space for a bigger tank ... got my eye on the 310 Square by Glass Cages, which is 48 x 48 x 31. How hard is it going to be to grown plants in that tank. What type of wattage am I going to have to push into it to get the light down in to the plants at the bottom?

Hah. Was just coming to post the exact same question. Just got a 31" deep 55g and have no idea how to handle the lighting.

Wattage isn't your issue, intensity is. It all depends on what kind of plants you are wanting to grow in there.

huh. guess ill figure it out...lol

intensity. My old man got a 8 bulb t5ho from aquariumplants.com with super shiney reflector(truckers and gangsters alike would be jealous) and 8 80w 6500K bulbs.

This is on our 210g which is 30" deep.

So just up the number of bulbs to make up for the depth?

number of bulbs and wattage.

Intensity is the key, but if you arent growing live plants in there, the intensity doesnt matter much.

the more you add the brighter it gets. however you can achieve the same effect by using less quantity of more powerful bulb$.

How do you increase the intensity? Don't you do that by simply adding more lights (i.e., wattage)? I was thinking I would outfit it with 8-10 of the 96 watt kits from AH supply.

You may want to consider hanging a MH unit over the tank. Should work nicely.

yes or converting to higher powered bulbs.

I'm in the process of getting rid of my 150g tank just because it was 31" deep. It wasn't planted so ligting was not an issue with me. What I didn't like about it was having to go swimming in order to adjust any minor issue on the bottom.

For example, when my fish decided to rearrange my tank and drag the air stone out from under the rocks, I had to get a ladder, remove my shirt, and go in shoulder deep to fix it. It's cute the 1st several times something like this happens, but eventually it gets old.

Be sure and put some thought into how you are going to get those plants in there and keep them maintained. Also, learn from my mistakes and fish-proof the tank as best you can. If I could have spent less time swimming in it, I would have enjoyed it much more.

All too familiar with swimming in my tanks. Its bad when you can't use deoderant because you know you will be working on your tank that day...

So higher tier lighting, T5HO should do I suppose.
