Fishdude Posted March 7, 2021 Share Posted March 7, 2021 So I'm still a novice but I noticed in watching videos of so many fish rooms and stores that many experienced aquarists drill all of their tanks. I understand the basic concept of a sump for single large tanks but I'm wondering about these systems with so many smaller tanks rigged together. Why do they do this and what's the benefit? Where does the water flow to, and how much of it needs to drain? Does this prevent the need for a regular water change in those tanks? Maybe dumb questions but I'm super curious about this.

joseph lambeth Posted March 7, 2021 Share Posted March 7, 2021 so are you asking about drilling for auto water change or for a sump? Link to comment Share on other sites More sharing options...
OceanTruth Posted March 7, 2021 Share Posted March 7, 2021 (edited) Usually they drain into a larger pipe that leads to the home’s septic system or they rig a drain that leads outside. When you add water to the tank, it overflows through the drilled bulkheads. So running clean water into the tank for a period of time effectively gives you a water change of a certain percentage. Hope that made some sense. I’m not the best at explaining things clearly and concisely. Hopefully someone else can explain it better.

I've seen plenty of content about the sunps, especially for the 800 gallon tank. I was wondering how an auto water change system works. Link to comment Share on other sites More sharing options...
joseph lambeth Posted March 7, 2021 Share Posted March 7, 2021 so basically an auto water change system works by drilling the tank installing a bulk head at a preferred height of the water line in the tank or tanks. without going into too much detail on building the system basically your building a drain system which flows into a drain to sewer, pond, or where ever you want the water to go. next is building basically a water system around the room so you can drip or run a certain amount of water into the tank flushing out bad water or used water into the drain lines and leaving fresh water in the tanks so that makes up an auto water change. Are you looking for like a build structure on the total system or just the understanding? Link to comment Share on other sites More sharing options...
Fishdude Posted March 7, 2021 Author Share Posted March 7, 2021 I think I understand the basic concept, essentially a sloped drain to remove water and then a nozzle to replace. I'm not sure if it's something I should try building when I set up a fish room as it seems complex. Is there a good place to look at the way people structure their systems? I have an issue with my water in that it will need to be heavily treated before being used. So I'm not sure if a RO/DI system can be used with an auto water change setup.

joseph lambeth Posted March 7, 2021 Share Posted March 7, 2021 so you can install the filters like an RODI system to filter your water before it goes through the system to your tanks. I would look at deans setup and i would study it and copy most of it honestly if i had a room where i can make a fish room. I run 7 tanks in my bedroom of a apartment for breeding I honestly would always do auto water change in a fish room. 1 Link to comment Share on other sites More sharing options...
joseph lambeth Posted March 7, 2021 Share Posted March 7, 2021 also understand if you had a garden and or a fruit tree or something you could run the water from the tanks to that and you can be using 100 percent of your water efficiently. Link to comment Share on other sites More sharing options...
Fishdude Posted March 7, 2021 Author Share Posted March 7, 2021 The garden idea is a good thought as ae will have a very large yard and gardening area. I imagine that's mostly useful in summer. Our water is super hard (think limestone quarry) so it needed a water softener, but sodium ions are no better than excessive calcium. So I'll need to have it run through that filtration before it's usable. I do worry about wasting water if I scale beyond about 10 tanks. The good news is I absolutely will have the space based on comparing the room I'll be using to the way Dean had to finagle that furnace and hot water heater...

joseph lambeth Posted March 7, 2021 Share Posted March 7, 2021 I believe that will be the best way to build a fish room run your water to a garden just install a 1 3/4 grey water pump to pump the water out to the yard. are you a member of the aquarium coop?

Fishdude Posted March 7, 2021 Author Share Posted March 7, 2021 Yeah I just joined last night. I've been watching the videos for awhile now. Link to comment Share on other sites More sharing options...
gardenman Posted March 7, 2021 Share Posted March 7, 2021 The focus here has been mostly on using drilled tanks for water changes. They can also be used for a central filter system. One large sump filter can handle multiple tanks with just one system that then needs servicing. There's a greater risk of disease spreading unchecked, but that can be minimized through the use of a UV sterilizer. Link to comment Share on other sites More sharing options...

I like this idea too, although I don't have any experience with designing or building a sump system. It's a bit intimidating, especially when I use a lot of plants and sponge filters already and it seems to do the job for the number of tanks I have. At what point is it worth having a multi-tank sump? Link to comment Share on other sites More sharing options...

At what point is it worth having a multi-tank sump? A large sump system filtering multiple tanks gives you more stability. A ten gallon tank can crash pretty quickly. Twenty ten gallon tanks with a fifty gallon sump gives you 250 gallons of water which is a bit more stable. As a general rule with aquariums, the more water volume you have, the more stable a system stays. Things can go wrong quicker in small volumes of water than in large volumes of water. With every tank connected, you're dealing with a much larger pool of water. If things do go wrong, they tend to go wrong more slowly and gradually. You can still use sponges and plants in each tank also. 1 Link to comment Share on other sites More sharing options...
Jungle Fan Posted March 8, 2021 Share Posted March 8, 2021 A large sump is a great way to filter large amounts of water. I had them in my 150 and 175 gallons I kept at different times in my years of fishkeeping. I loved them, would highly recommend them the only thing to remind about using them in a multi tank set up is to make sure you use quarantine tanks for any new fish so you don't introduce anything to the whole system. It;s a bear to get get things controlled in one tank, but with multiples it is simply a must; but there really is no reason to not use a set up like this in a fish room, it just makes sense.
