    400 gallon tank build

    I have a lengthy post on aquarium forum, I will post here too though

    The tank is 30” deep, 36” tall, and 83” wide. The viewing window is 72x30 with 3” inside plywood.
    i used 10 gallons of epoxy to line the inside of the aquarium and used a few types of pigment in the epoxy.
    its bottom drilled with 2-2” pvc returns, and a 1-1/2” pvc supply. The sump is in my basement and the tank in my theater room.

    my “sump” is not 100% complete, but will post what it “will” be shortly, I’m just waiting on my pond armor and epoxy to seal my cistern.

    the return goes from the tank and back about 40’ to the back of my basement where it goes into a “breakout tank” which is a 40g breeder, then it flows into another 40g breeder filled with poly, from there it goes to my cistern which is 7.5’ x 6’ and filled to 6’ water level to give me room for a failure of some sort. Cistern will have 10 cu ft of k1, and I hope my cor20 will be able to supply enough. I am going to have a 400gph alpine pump to fluidize the k1.
    i have a 16” pool pump that will be filled with a few pounds of pool filter balls, and as much purigen as I can fit in the strainer pot.
    another pump takes water through my softener resin vessel which has 4 cubic feet of carbon.
    will have another pump going parallel through 5- 5micron whole house filters.
    still need to figure out which pump I will use to feed my 100 watt uv.

    i am still debating on a bubble system for the cistern or not…

    the whole system will have auto drain and ato, I have an ro system that will do around 4k gallons a day, it’s at about 20% waste water but I get between 3-6 tds from it.

    I use an apex for my automation and that will make water changes a breeze.

    the water heater will be through my boiler system for my hydronic heat and be inline with my supply to the discus tank.

    future expansion will be another 400 gallon for large fish/stingrays that will sit over a 125 gallon on the floor that will house a turtle. Everything will utilize the same sump system.

    all of my electric will run on an inverter system with solar panels with auto shore power backup.

      Wow and what a man cave. Guessing you have quite a bit of aquarium experience with large tanks. Is the tank a custom build?

        Wow, I absolutely love it! Great work so far! I would really love to see more info on your DIY tank build out and honestly the Battery back up solar panel system is right up my alley. I have done this on small tanks, but nothing like this, Though I hope to someday, How many watts will your tank use and whats the Amp Hour rating of the Battery system and its configuration. Did you go Lithium or lead acid? Are your batteries draining past C50 or are you shooting for draining no more than C 80? How many solar panels are you using and whats the set up like?? what Mppt charge controller did you go with? Also where are you located? do you have to worry about diminished solar output in the winter? ( my big pit fall in the Northeast USA) So cool to see this.

          What brand/model RO system do you have ?

            I couldn't agree more with the ones posted above - this looks amazing and would love to learn more about how you planned it all out!

              My RO pump controller is Culligan, it originally came with a 2000gpd element, I replaced that with a 3000gpd and added another 3000gpd in series, water pressurizes to around 190 before the elements. I only have a 400 gallon holding tank though. All the water in my house goes through a resin vessel filled with charcoal first. My incoming water is between 600-700 tds.

                I had a 200 gallon tank for about 10 years, the acrylic sump I built under it would occasionally leak because the water level was too high, well it eventually rotted the stand and cracked. I repurposed one of the panels for this aquarium

                  My inverter system is all victron, I have 4 200ah agm renogy batteries. There are 14 400 watt panels. Have 2 victron charge controllers and 170 amps of possible charge output.

                    The tank is all custom built with the exception of using a piece of glass from my previous 200, I used all 3/4 acx except the glass “saddle” it has a 5/8 sandwich to hold the glass and silicone. I used an epoxy barrier coat on the entire interior wood surface after I fiberglassed the corners. All of the epoxy is around 1/4-3/8 thick that I poured on each interior side, except the bottom I poured that at 1/2”.

                    i still have a little bit of plywood to add on the upper portions of the “stand” and want to put a transparent acoustic fabric over the subs to hide them. I also need to redo the piano hinge so it is on the outside rather than above the door so it sits flush.

                    I mounded the iPad there to run the apex app so that I can see everything here and wouldn’t have to go to the basement to turn anything on or off.

                      Victrons are great controllers...rock solid. I have a few here. Are you running 12v or 24v.

                      Are you running the tanks heater off Ac from the inverter or dc from the batteries?

                        Heater will be ran from the batteries, but it’s just a 24v signal to the zone valve on the boiler system. The only copper in the entire system is the heat exchanger for the aquarium heater

                        inverter setup is 12v for just the aquarium.

                          To do list this week is to apply to epoxy and polyurea to the cistern. I also need to add more light to the tank, I have 3 - 150 watt hqi and another 60 watts of led, and 60 more watts of black light to add to the tank too.

                            Anyone have an opinion on using these for lighting? I would probably get 3 of them. I like the idea that you can program them to come on and off slowly with a dimmer.


                            Create smart growing systems with advanced components like grow tents, fans, LED lights, and UIS™ controllers.

                              I think you might be able to fit a betta in that tank... wow impressive stuff. I wish I were handy. The extent of my handiness is plumbing a sump let alone a DIY tank build.
