125*125*65 1015 liter cube tank

**Slan** · 7th Mar 2004, 05:38

Hi everybody.

I´m getting my new aquarium next week, a cubic tank holding 1015Liter.
I´ve been wondering if the rule for 0,8w per liter is the same applying it to a big aquarium? I was thinking of having 2*250w Mh, and maybe one or two blue pl lights, just for the coloration in the water. I want to have a "carpet" so the light should be strong enough for that.

the filter situatíon is anoither problem, how much should I have ?
Maybe you could build something own, to keep outside the aquarium, like a big filter system so I don´t have to have any filters in the aquarium. i don´t know.

anyone have any good ideas? they´re welcome!

Greeting from sweden.

Hi Slan, what's the exact dimension of your new tank? Do you mean you do not want to have any piping in the tank itself? Could be done.

You will need an external overflow box. Your tank water would flow into this box. From here, you got 2 choice, either your tank water go directly to your filter ( I imagine you would want to use external canister filter) or you could channel it to another smaller tank where it is connected to all your filter. From your filter, the water would go back to the main tank.

Hi, The exakt dimensions is 125cm*125cm*65cm

Ok, what would i need then ?
could i build like a big nox with filter material and from that box to the aquarium again ?

For filtering, personally, I like to keep it simple by using canister filters like Eheim 2260. I will use 1 or 2 filter depending on the setup.

If you use a big box as a filter compartment, chances are in the future, that box would look disgusting and would contribute to the awful smell. Also, it would be a hassle if you would want to clean it one day. I suggest a pair of external canister filter. Water tight and easy to transport. I would try to get a picture of the external overflow box.

An external reactor is best used if you do not want to have any equipment in the tank.

Jeah.. you´re right BFG.
What´s a overflowbox ? don´t really get that, guess two external filter canisters would be alright too. not that difficult to hide. Can I dissolve the Co2 into the canisters ? would I need anything more then the actual things on the gastube then?

Have a good one.

Can I dissolve the Co2 into the canisters ?

Try not to. I will slowly kill your filter. Get a proper CO2 external reactor. It will cost you 70-80 bucks from NA or a more professional version at 120-160 bucks. For a 4 ft x 4ft tank.. I think you really have to plan with 2 big filters. Circulation can be a problem with big tanks.

maybe you would like to refer to oliver knotts tanks?
he doesnt use any canister filter i think

this link clearly shows the filter system that he uses ...

this link shows you how the overflow box looks like ...
if u have nifty fingers u can actually try making one!

Simon, the links that Anzai has posted (I-Box) is nearly similar to the one that I had saw. It is the best aqua related invention in my humble opinion. Hope you could order it to your place in Sweden. It's made of acrylic. I currently have 1 but I've yet to use it.

Back to your topic. From this overflow box, I suggest the tank water go into another smaller tank for the pair of canister filter to feed from. From the filter, one of the piping of the external filter should be feed into the external reactor. The water flow would return back to the main tank.

I have more question. Where would this tank be placed? Would it sit on a wooden cabinet or do you have something constructed eg concrete block?

**Slan** · 10th Mar 2004, 01:11

Hi.

It Would sit on a specially designed bench. Made of wooden material.

Iam yet to decide wther ia mgoing to use canister filters directly in to the aquarium or use a overflow box, and a second smaler aquarium. whats the advantages with the overflow box ? i must have tubes going into the aquarium still. it seems very unneccesary to me.

Have a good one.

**BFG** · 10th Mar 2004, 01:19

The advantage of the overflow box is that you do not need to have the external canister filter inlet tube to be in the tank. The water will flow into the overflow box. The only tube that you would see in the tank would be the outlet tube. You could hide this tube behind some tall plants in a corner.

The big advantage of an overflow system is that it can be linked to a sump which has a big filtering capacity. The wet-dry setup will alow for big nitrifying capacity and rate. However, using such system, one has to address the CO2-loss issue. Splashing and trickling will cause some CO2 to escape back into the atmosphere.

IMO, tubes are easier to conceal than an overflow box. There is also some plumbing involved to connect the pipes to the sump and to ensure that they are leak free.

Personally, if I do not have heavy bioload, I will settle for a cannister filter, which almost everything I need comes in the box.

**Slan** · 10th Mar 2004, 23:29

Yep. damn right 8] I´ll just settle for cannisters i think.

There´s another issue.
The lightning

I have 2*250 mh, will this be enough ?
I´m going to have glosso or hemanthius covering like 80 % of the bottom area so it´s very important that the lightning is enough..

Have a good one Greetings.

If you are going to have high light, CO2 will be just as important so I strongly agree that canisters are the way to go as you do not have to worry abput CO2 lost as in a overflow box.

**Slan** · 11th Mar 2004, 06:37

Yes,. Co2 will be injected. the hardware style

But will the light be enough for bottomgrowers, like glosso, hemanthius or so?
and will it cover the entire bottom space?
