Going from a 75 to a 270

[owenb01]

I am very new to this forum and even though I have made the effort, I haven't been able to find an answer to my question. As it says in the title, I am going from a 75g to a 270g. I will be transfering all of the water and rock (100lbs), adding an additional 200lbs of cured rock, and making a 6in DSB. I will be using a 75g as a sump, a fluval 404 as a phosphate reactor, blah blah blah. My quandry lies in the fact that I am moving into a house from an apartment and we opted for the wood floor upgrade. I do NOT want to ruin my wood floors, so I am wondering if I should attempt to reseal the tank after the move. The last thing I need is a leak; I have filled the tank in my garage at the apartment and after a week it hasn't leaked. I know the tank is sound now, but I am concerned with the flexing that will occur during the move. The tank is 7x2x3 high. If I need to reseal it, how do I do that? Also, with those measurements, how many pounds of aragonite do you think I need to make a 6in DSB? I am just keeping angels, will 300lbs of live rock be enough for filtration in addition to the sump? One more question; the tank is not drilled and I intend on putting 2 or 3 overflow boxes on it. How many gph do they need to pull (each)? Thank you.

I didn't mean to say I was just keeping angels, I also have acanthastreas, micromussas, and euphyllias. I know it's risky to keep any angel with LPS's (or SPS's, for that matter) but I have had absolutely no problems in two years. Anyway, that's secondary to my two main questions: do I need to reseal the tank and how should I plumb it?

You can't really use silicone on top of cured silicone, if that was your intention. It won't adhere to it. To do it right, ALL of the old silicone would have to be removed first. Personally, with a tank that size, I wouldn't feel safe doing that unless I cut the tank completely apart and reassembled it. Anything else would be a bandaid and may not hold up. Might be best to just leave it alone if it is not leaking now. Good luck with the wood floors.
