O.K. So it is 2 weeks after i started that upgrade. When i post a week ago I was little depressed. But now i feel a lot better. I got some pictures for you guys how my tank looks now. I had two problems as you know. First i thought the flow <pressure> was to slow. In ,my 90 that pump was blasting and i had to slow this by turning shut off down. In this tank i thought the flow is slow and i was afraid that there is something wrong with my plumbing. But after a lot of thinking i realize that now water goes to two overflows not one like before and each overflow has not single but double returns. So before water enter the tank with one return now from four. When i shut off one overflow and plug with my finger one exit of second overflow so the water was entering just from one it was the same blast as in my 90 before. And to make sure when i unpluged pump and plug back in water level from my sump was droping as fast as before. So i think this is o.k..Second issue was a little leak from return. I explained this a week before. Worst was like a drop every 2 min. next day, drop every hour maybe, next,little drop just hanging there right by nut under tank. Three days later it stopped. Now it is been like 11 days . No leak at all. I heard that saltwater does seal small leaks. What you guys think? Should i fix this?? I'm confused, should i fix something that is good? So right now I'm pretty happy. What you guys think of my tank???? Thanks for all good comments before!!!
