    I'm thinking about adding a closed loop system to my 220 Gallon tank. Will not be drilled. I also already have a good wave maker. So my thoughts are just consent flow no random water moment. What i'm planning is 2 pumps, intake in the overflow boxes. The two output pipes would be right beside...

    OK, so here we go. I'm about to start setup on my third tank, this one will be a 180. I'm planning on drilling for a closed loop system, and also putting on an external overflow box to run water to the sump. My question is this, am I better off running more GPH through the closed loop and...

    OK. I wouldn't say I'm "new" to the hobby, but I do consider myself a "novice". That being said, I am buying a new 140g tank for a reef setup. I have a 75 tall tank now and I hate it. It's too narrow to do any decent aquascape designs so I'm upgrading to a nicer tank. It's drilled for CL, and I...

My plan is to use a Reflow pump with the outlet inlet size being 1.5. For my intake i plan on using two 1 1/2" bulk heads with screens on the back wall of the...

    I am gathering equipment for my new 280, and I had two pumps fall into my lap at very decent prices. They were not my original choices, but for the price I paid, I am happy to use them. The two pumps are a Dolphin Ampmaster 3000, and an Iwaki md-70RLT. My decision lies in which pump to use for...

    Good Morning All, I am installing a closed loop for circulation. I currently have a Quiet One 4000 as my return pump. At the end of the return, I added a Hydor FLO deflector. Inside the 90 g display, I have 2 Koralia Evolution (750 and 1000 gph). I am adding a second Quiet One 4000 (ordered...

    Guys, considering the width of this new tank (30") should I be considering adding a closed loop with spray bars? Is it possible to do it from the bottom only? I'd prefer not to have pipes behind the tank because it'll push it out even further into the room. I wouldn't even consider doing this...

    I posted in the general discussion forum also, but not sure where to post. We have air in our closed loop system. A LOT OF AIR. Last week we noticed air in the closed loop system and it killed our chiller. We replaced the chiller, cleaned the pump and thought we fixed the problem. We've been...

    I have made up a rough draft of what i was thinking about. Was hoping some of you guys could look at it and tell me if I am all screwed up or on the right track. Thanks The top 2 holes are for a 1500 gph overflow box The center hole is for 2" bulkhead for the supply The left and right center...

    Ok, before I move my 150g off the floor and onto the stand - I thought I'd get your thoughts on "any more holes needed". Today I drilled 10 holes in the back of the tank. (4) 1" holes will be used for the BeanAnimal Coast to Coast overflow. (2) 2" holes will be used as the intake for the...

    I have my 150g tank all ready to drill. I'll be adding the BeanAnimals Coast to Coast design to feed my sump. Question: For the closed loop system, how many holes (out / in) and where on the tank (sides, back, lower, top, etc) would you recommend I place the holes. Thanks for your help.

    Hey guys, I got a 210g tank and i'm in the planning stages right now. I am really have some trouble on the closed loop design. I was going to get a Dart pump, but after thinking about it i might need more. 3600gph isn't very much in a 210g tank is it? So should i move up to the Hammer head or...

    Ok so i have a 75g tank about to start over and move thinking about doing a closed loop. How do i do it and what size overflow and pump do i use? How does it all work?

    I will be setting up a new tank in the new year. The closed loop will have 2 pipes coming up with live rock surrounding them. I thought it would be a good idea to drill small holes - or maybe big holes - in the pipe going throught the rock to introduce flow inside the rock. i thought it would...

    So I am adding some necessary more flow to my 300g bullet with a closed loop. I already posted this question in my build thread but thought I might get a better/faster answer in here. The hammerhead pump is currently running restricted because the overflow is at max capacity. So I am adding...
