sump design

I recently picked up a Two Little Fishies Kalkwasser reactor. I know most people run them on RO from the ATO line, but I already have a good ATO and AWC system up and running and I'm comfortable with how it is behaving. Adding another variable to a complicated setup is daunting, and it doesn't...

Calling all sump designers! I have this old 40 gallon that used to be a freshwater tank, with dimensions 99cm long x 39 cm wide x 42cm tall, that I would like to turn into a sump. To be honest I have no idea where to start with this. My first question is what would be what is the best way to...

Hello fellow reefers, first time poster here after being a loyal lurker for a few years now! I am currently preparing to upgrade from a 60-70Gallon reefer 350 (lowered to 18inch height) to a 10'x24" wide x 18" tall 200G~ tank after moving in my new house. (Photo of the sump/stand below) I...

Hi all, Would really appreciate some advice / input on the sump for a 1.8m (6ft) 180g display. I'm trying to keep things simple, also note the sump size can still be changed, the dimensions was given by tank builder. The width of sump not displayed is 50cm/19.6in. 1. From face value, am I...

So, my LFS has two identical 60” x 18” x 16”T, 1/4” thick rimless acrylic sumps for their identical dual single-drain overflow 180g rimmed glass tanks. They are very old-school, and gave me creative freedom to update their filtration to the 21st century! Both are the LFS owners personal tanks...

Hey all. My sump is way too small on my Red Sea 300 G2 I have a reefmat 500 in there. I don’t need the room inside the stand for anything else other then the sump since I have all my controllers and wiring etc in a controller board, so I’m ok with going with a sump that takes the whole space...

as background i have a 29g bio that has been running for close to 12 years. with 2 clowns, starfish/snails/crabs... also have a home build 30g tall tank with a diy sump i made 8-10 years ago. sump is way undersized(5g). but has ran with 2 clowns in it for 3 years now. had other fish before...

Hello there reefers! I am trying to design a tank+sump system to house a palm-sized common octopus. I've had a small fresh water tank (~8 gallon) running for about 2 years now but I am very new to saltwater aquarium and especially sump design. So I would really appreciate some advice! I have...

I'm setting up an observation tank that I would eventually like to turn into a mantis/frag tank one day. It came with this acrylic sump that had a trickle tray w/ bio balls and a sponge in the bottom separating the chambers. For the observation tank I could honestly probably run that setup for...

Howdy everyone, I am planning my transition from freshwater to saltwater over the next few months and I need some help designing my sump. The aquarium is 67.5 gallons, like a tall 55g. I have kept a reef with my dad when I was a teenager and helped him set it all up, that was 15 years ago and...

I have a 60 gallon cube with a 18 gallon eshopps sump and eshopps pf-800 hob overflow. Looking at the Syncra SDC 6.0 that has a flow of 530-1450 or the Syncra SFC7.0 that has a flow of 800-1900. My return pipe will be around 4 feet with two 90 degree angles in it. Would you go with the 6.0 or...

Included diagram should hopefully give a good sense of what I’m asking. Do people prefer sumps that dump water directly to the mechanical filtration or should they have some sort of spillover “staging area”? I’m assuming the spillover staging area might keep things a little quieter, right? Also...

Hello everyone, I apologize there is a million posts on sump design and honestly I've spent the last couple of weeks trying to understand them. Gathered as much knowledge as I can but I can't seem to figure out same basic stuff, I see many complicated designs and I don't know what I need yet...

My little standalone HOB filter isn't cutting it anymore. I have no Skimmer and rather than just add a little HOB Skimmer I will be converting a 10 Gallon I have been using to prep water for water changes into a sump. Frequent water changes are getting annoying and I get frequent algae and...

I currently use an Oase Biomaster 250 on a 20 gal tank, but I'm building a cabinet sump. I've heard of others using a canister filter instead of a return pump, the difference being that a filter sock and bio media are no longer required in the sump. Mine would just be a skimmer and a refugium...

Dupe, please delete

I'm doing research ahead of time before buying and setting up my first saltwater tank. It will be FOWLR, with the exception of possibly an anemone down the road at some point if/when I'm confident I can take care of one properly. The display tank will be in the range of 20-30 gallons and the...

Okay so I have this tank I’m about to set up and upgrade to but only thing left for me to do is the sump. I have my complete tank setup everything is ready except the sump. sump design is incredibly difficult for me to understand anyways, it doesn’t help that there are no baffles that came...

Hello All, So I'm looking to get a waterbox 60.2DX because the standard sump in my opinion is straight trash. I am having trouble understanding the DX sump for the 60.2 because there is an ATO reservoir in it when I could be using that real estate for a refugium for my tank. (picture below for...

Hi all, I am looking at new sumps, and I wanted to compare different sump builds so I wanted to find out what people rate. So question, what do people think is the best sump out there and why? And if you were to pick a custom-made sump over a stand buy off the shelve, what makes it need to be...

Hello my friends, after 15 years assembling freshwater fish aquariums, I decided to enter the world of reefs where I have always followed and studied but for reasons of cost and time of dedication I left it for later. But the time has come. that it's alright and i don't do big things I will...

hello, so i have a fluval evo but would like to upgrade. im looking into a fijicube rimless overflow that is predrilled and ive been toying with the idea of using the evo as a sump for this, im not an expert and would like some help with a design, so im thinking of and another divider in the...

Hi everyone, I’m planning a bean animal backpack overflow on my new build, and also want to include an automatic fleece roller (the only style available here is pictured). Any suggestions on how to plumb the two return lines from the bean animal into the fleece roller? I’m sure someone must...

Hi all, so smy 525XL that I am attempting to give a good clean out to is going well in the actual tank itself, not so underneath as yet, but I thought before I get to far ahead, I should just check for any leaks. So I filled the overflow box in my 525xl tank to see if no 1.) the 3 pipes that are...

I’ve been slowly working on this tank build. I purchased the Neptune Systems ApexEL a couple of years ago, but never installed it. I doubt if the PH probe is still viable, but I want to reach out to this group for your thoughts. Is the probe trash, or can it be salvaged Also, I’m still trying...
