Jebo R375 as a marine tank

[hazymranch]

I had kept freshwater fish for years and this is my first marine tank. I bought a Jebo R375 (140L) tank because the molded acrylic made for great viewing from all angles, specifically from my son's crib, and because it came with a full hood with a wet/dry filter and individually switched lighting (2x20W) incorporated into it and stand.

Now that I have read several books on keeping marine tanks I have come to find that it is fairly inadequate for the purpose. For one, the hood makes it impossible to hang anything off the back of the tank, which means that everything has to go inside. Not ideal, but really an aesthetic problem...except for the skimmer, for which there is no room. So, I have designed and am in the process of building a sump (80L) that should overcome my filtration shortcomings and add stability due to the extra volume. I would like to introduce invertebrates at some point and evolve into a mini reef tank and so I have been looking closely at the lighting. It came with 2x18W T8 bulbs and the ballast is rated to 40W. I don't even know if the bulbs are full-spectrum bulbs and I can't find that information anywhere. I swapped one of the bulbs out for a blue actinic 20W. I have been reading that I should have at least 3W/gallon so that means 120-150W is required. Obviously the 38W I am currently running falls quite short.

So, ot the first of my questions: Does anyone know much about the Jebo system and specifically what kind of spectrum the Jebo T8 bulb is? How can I add additional wattage to this type of tank? Does anyone have any experience in using the Jebo acrylic systems as marine tanks? What else will I have to do to retrofit it for marine suitability?

Any guidance would be greatly appreciated.

My brother has a via aquatank (same thing)

he has taken off the filter and put in a skimmer, soon we will add an overflow to a sump to put the skimmer/heater in and beefup the lighting even more as he wants an anemone and a clam (thanks cookie)

the stock lights are fairly average and i wouldnt recommend them for a serious reef tank

Thanks Brian. I was/am hoping to avoid removing the filter if possible. If I move the bulk of the biological filtration to the sump, which is my plan, then I would like to use the former filter compartments to house chemical filtration substrates like activated carbon, ammo lock, phospho rid, etc.

Aside from that, the tank's proximity to my son's cot makes me want to maintain as much of a complete lid on the tank as possible, as well as to minimize evaporation loss.

That said, I am finding that it may well be unavoidable. I may have to at least fashion an acrylic lid for the current light hood space and place a new fixture on top.
