Help - Tropical Tank To Marine Tank Conversion

[Arimus]

Hi,

I'm currently looking at getting a larger tropical tank to replace my juwel delta 300 corner tank (so I can keep more catfish )...

As the Juwel is a nice tank I'm considering converting it to marine but so far not 100% sure what I'd need to convert it.

Currently I reckon on needing

1. Upgraded lighting

2. Power head(s)

3. Sump

4. Wier

5. Protein skimmer


I can figure out 2 and 5 easily enough its the rest I'm having issues with...

For the lighting does anyone have any suggestions (the tank would be for mostly soft corals and marine fish)

For the sump I'd use the largest sump I can fit in the cabinet but then I'm unsure on how to get water from the main tank into the sump and out again (Currently its got two external filters running which would move to the new tank)... would just a simple pump in the sump used to pump water to the main tank then a weir with overflow down to the sump work?

I've got the tropical side of life worked out - marine with all the equipment needed seems more complex but as much fun

(Finally managed to arrange my nano reef so all the corals are happy and not sulking )

Well, as for lighting, what are the lengths of the two straight sides of the tank? Corner tanks with their near cube-like shape tend to really lend themselves to metal halide lighting. They're difficult to light with flourescents cause they're not shaped like rectangles Often times a single big halide, or maybe two smaller ones are the way to go here though.

You're right about the sump. You'll have an internal weir in the tank and then drill out the bottom or side wall for an overflow hole (using Durso Standpipe or Calfo Overflow respectively). Then you use a pump in the sump (or external to the sump) to push water back up. Sumps on corner tanks are a bit tricky cause of the shape of the tank, so lets see what size tank you can fit in there before we really go reccomending one
