I recently installed a CPR 50 and an Eshopps Nano Cube in my 29-gallon reef tank. The CPR+Aqualifter is definitely the way to go if you're worried about overflow. Also, plug the Aqualifter and your return pump into a well-rated battery backup and you'll virtually solve the problem. A sump is great if you can find a way to squeeze one into your system.

I like the idea of using an overflow box, it immediately takes a lot of questions I have in mind. Regarding tubing to allow water to pass, can we use regular clear thick plastic tube(found in hardware stores) that is slightly smaller/larger on the diameter of the hole of the return/overflow holes to attach and secure with aquarium safe glue/ cable tie? Or is there a certain kind regarding brand/material? Thanks- Erick.

Yup, these work pretty good! As a backup, its a good idea to also get the "smart level security" water sensor, just incase the overflow fails for whatever reason. But these overflows work pretty well, and are a great solution for those that can't or prefer to not drill tanks.

Great video. My hubby and I both are afraid of drilling so thinking of a hob overflow, are they safe? Ihave read review on amazon that many people say they turn off when feeding or simulate a power outage and always works! I have decided to move our aquarium to the den where I have tile versus wood in family room, but still a flood could make its way out to m y hallway that is wood or living room! Scary thought but drilling and the plumbing seems way more difficult! I have read there are prevention ways such as drilling a hole on return and other means. I dont get how the water makes its way back to aquarium though. Is that done by adding another pipe or tube and a duckbill? Would I need a pump? I thought of buying used but all the used ones I see have the dealer drilled giant overflow boxes so dont want that!

I am going to be adding a sump to my already established reef tank but I have a question. Will adding a sump change the salinity in the main display? Or will it stay the same if the sump and display match salinity? I don't want my fish and corals to go into shock over parameter swings.

The single pump that returns water back to your aquarium will control the rate of flow through the system. Each overflow box has a flow range and you need to choose a pump within that range for proper operation.

I dont get how a sump filters if you dont have socks and a sponge. I rarely see media in a sump just water and a skimmer and a pump, so how is it filtering? Do I need a carbon reactor to run carbon, does the skimmer do all the filtering if not anddoes a refugium filter as well? I dont really understnad them other than people have cheeto and copepods and light ext but dont get how that filters. I am a newbie andmy only experience is with 1 x weekly waterchanges with my 10 gallon no skimmer in my kitchen but I love that so much I want to get a big one now. That was considered my test run aquarium but I will say I am sick of weekly water changes and I have 2 freshwaters as well!

It is best to slightly oversize the pump and be sure to account for your plumbing/head-pressure. I have a great video all about choosing a return pump that I linked below.

@BulkReefSupply

No, an overflow box or drill it are your only options for adding a sump system. You can consider using a canister filter or hang-on equipment only which is certainly doable, I would just recommend that you go light on the stocking with fish. The hang-on gear is a little less effective but so long as you stock lightly and maintain it, you will do great!

@BulkReefSupply

Most hobbyists will have the skimmer inline before the refugium. The idea of thinking here is that the skimmer should not come in contact with the water exiting the refugium as it will contain beneficial micro-organisms that the skimmer could remove.

@BulkReefSupply

+Andrew Fierro Yes, the air nipple should be connected to a suction pump or directly to your return line which will create suction and ensure the overflow can return back to normal operation in the event of power failure.

I have been considering a sump system for my 75g mixed reef but I am very hesitant because of the horrors I have heard regarding over flows. Since I live in a condo unit and have neighbors below me I can not risk this happening not even once. What assurances do you have regarding over flow protection?

@BulkReefSupply

8 жыл бұрын

+Nick Torres The CPR overflow is very reliable when used with an Aqua Lifter pump; even in the event power is lost the overflow will start on its own. The main concern here is ensuring your sump is large enough to hold the amount of water that would back-siphon down your return pipe when power is lost. When plumbed properly, this should be minimal and you will not run the risk of overflowing the sump.

Your sump's water level will rise during a power outage, no doubt. Really any time your return pump is turned off. You'll want to make sure that your sump is able to handle that additional water so that it doesn't overflow.

Never used a sump but i`m considering one... My question is..In the event of a power outage(happens a lot here) what keeps the overflow from draining the tank? Sry if this is a dumb question, I`m new to this!

@BulkReefSupply

7 жыл бұрын

The overflow pulls water from the surface of your aquarium and therefore once water level drops below the overflow, it can no longer pull water from your tank. The risk actually lies in your return water line which is typically below the surface of the water which will "back siphon" water from your tank into your sump. Using a check valve along with plumbing the return water line in such away to prevent the "back siphon" will avoid this problem . You also want to ensure your sump is large enough to hold the extra few gallons that will inevitably drain from your tank in the event of a power outage.
