Hello, This is my very first post. My name is Mike and I live near Modesto, CA. I love aquatic life and currently I have 3 planted tanks that I've had up and running for nearly 2 years now. I have 2 - 55 gallon tanks and 1 - 20 gallon tank all using the Walstad method and thriving. I successfully bred blue dwarf gourami and sold them recently and so I'm onto my next challenge Since I work at home full time, I finally decided to take a big leap and get into the Saltwater world specifically reefs. I think I got a great deal on a like new 135 gallon long on black stand and includes Tom Rapids Pro Filter RP3 protein skimmer pump with 3.5 gal. reservoir tank , two powerheads, heater, two stage lighting hood, stand has small water damage but not bad at all. He was asking $200, but ended getting it for $150. Was this a good deal? So here I am today: Here is my tank pics and sump. I'm in a HUGE dilemma and can really use expertise as I build out both the stand and tank. So as you can see my tank which actually comes out to be 140 gallon 72" long x 18" wide x 25.5" tall has no overflows built into it....not sure if this is a good thing or bad yet lol. It came with the Kollercraft Tom RP3 sump which I haven't even used and HATE IT already . My cabinet in the pics I attached is still being built and I have some middle supports to add but not sure if I should entomb a large sump/refugium all in one in there that I won't be able to get out or move the supports to make room for a smaller sump/refugium? I can still change things if I have to. It measures 74" long x 24" wide x 28" tall. I used 2x4 in the construction of it and will still be putting up the walls in all the way around with 2 smaller doors on either end and 1 large door in the middle. My question is this. I don't like the RP3 hang on back and not sure how you all feel about it, but I want to get rid of that sump and put the largest refugium/sump all in one below. With legs in the way the largest measurement of a tank I can put in the would be 37" long x 19" wide x 16" tall so that's almost a 50 gallon tank which I would love to do but not sure. I can maybe go 18" tall but I would basically have no room to reach in there because the top 2x4 would be in the way. So my other question is should I cut new 2x4's that are taller to raise the table higher than 28"? Also, can I build my own refugium/sump from scratch and buy a 40 gallon tall or 50 gallon long tank from Petco when they have the $1/per gallon said and then glue in my own glass chambers etc? Or is there a better way like ordering the kits I see on ebay that I could put in my tank? I should probably add that I'm doing something crazy and adding 4 (I wanted to add 6 casters but my neighbors said I'm way over killing it and 4 would be fine lol) - 6" caster wheels that each support 650 lbs. because I will need to move this in a few years when I replace the floors in my house or decide I want it somewhere else. So currently with casters it will stand about 34.5" tall then the tank on top of that which is another 25.5" inches. Since my tank is glass, how can I add a MUCH BETTER pull and return water line with new pumps? Should I do that or what else would you suggest? I was thinking 1.5" pvc painted black one on each side, one of them will be suction and the other the return and I was looking at getting 2 of the Jebao DCP-5000 or DCP-8000 and then some type of system that monitors both motors so that if 1 fails it will kick them both off to prevent flooding. OR do I go to a local glass shop and ask them to drill 1.5 or 2" holes at the bottom and if so approx. what would that run? I don't feel safe drilling glass at all. I'm not in a hurry to build this, and want to build it right. So PLEASE tell me what I need to do Do I raise the stand higher? Do I pipe it the way I'm thinking? And how do I prevent the refugium underneath that I want to put from overflowing? I know I rambled on and on and appreciate everyone's help! As you can see my mind is ALL over the place and I just needed to stop for today and stop stressing and hopefully hear back from someone tomorrow morning when I wake up to start again and you all can give me good solutions. PS. - BTW is that metal bar in the top middle of the tank suppose to be there to hold the tank together as it gets filled with water? My neighbor says that's crazy and the previous owner must have made it himself and I tried to tell him it's normal to have that for a tank this size, but I am wondering a little if I'm right and is it ok to have that bar?
