Well my tank crashed last night so now it is time to rebuild and start over. So now I have choices. Do I rebuild my 46 gallon bowfront or upgrade to the 90 just sitting in the garage? I have everything for my 46 gallon. 6*39 watt Tek light, 150 gallon skimmer, mag 7 return pump. Don't have the extra cash to replace anything or add bigger stuff right now. I will have to build a stand for the 90 if I use it. If I upgraded to the 90 I would have to use the light and skimmer I already have. So that would be a 3' light over a 4' tank. Now the 90 is missing the center brace from the top trim. The glass is thick and it use to be up and running at a friends hoise wothout the center brace but i think it shoukd have one. Is there a way to sdd onem will it help if i did? Trying to figure out what tank to build because I have to rebuild one. What tank should I build? Would it be worth it to build the 90 with that light fixture. Would like to be able to keep SPS again. Would that much light be enough?
