Hello everyone and thanks to this great group for existing. I have a 90 gal about 5 years ago but I decided when I bought the house thanks to God, to do this great project of a 125 gal on the wall and update myself in almost all systems, Lights, Pump, Sump, Etc. The sump is the Proclear 300 red flex 4 in 1, 2 Radions X30 Blue G5 and Reef Octopus Various 8 return pump on the way. 2 tanks of 55 gal each for a Mixing Station, Skimmer Reffer 300, Plumbing Red with gray. I will be updating little by little while I am going forward because I am also under construction in other parts of the house. If possible, I would like your advice and criticism especially on the complete plumbing installation for a perfect system. In the back of the tank I have the drainage and the water I need to feed the Ro / Di. Ohhh. 3l tank has dual overflow with two holes in each. I want to make it mixed and with more SPS in the near future. And I would also like to put some Manifold on it. If someone had a diagram, photos or videos similar to the plumbing that I want to do it would be perfect. All the red pipes are 1 ", and only the manifold is gray, which I plan to do with 3/4. I plan to leave the return pump with 1", putting a cross at 3/4 for the manifold and continuing at 2 overflows. with inch. And the drop to the sump, I bought those two white tubes that are in the last photo, I don't know what the drop system is, but I plan to go down with 1 "also to the sump. Thank you very much to all.
