First Reef Build – Finally Up and Running

After a lot of planning, building, and collecting parts from everywhere, my first reef build is basically in the books. Some equipment I bought new, some came from Facebook Marketplace, and a few things I built myself.

This build ended up being a really fun project — especially the aquascape, which my daughter and I designed together.


---

System Specs

Display Tank Mailrineland 75gal.

Standard glass display (drilled)

2x Synergy Reef overflows

1" centered return

3D printed 1" Loc-Line splitter


Stand

DIY stand based on a YouTube design

Modified slightly so the panels fit together cleanly

Lumber cut at Home Depot


Flow

Octo Pulse 2 (left side)

IceCap 4K Gyre (right side)


Lighting

AquaMaxx Prism II

GRO Refugium light



---

Aquascape

120 lbs dry rock

Designed and built with my daughter over a couple weekends

Built with several arches and a separate spire for the anemone


Sand bed:

140 lbs sand

Deep enough for future sleeping wrasses

Also planning for an engineer goby waiting for it to be shipped from Dr.Reef



---

Current Livestock

Current inhabitants:

2 Black Storm Clownfish

1 Bubble Tip Anemone


The anemone was placed on its own rock spire and, by pure luck, stayed exactly where we put it. The clowns immediately started hosting it.

Currently in quarantine:

Yellow Tang

Tomini Tang


They will be added to the display soon.


---

Sump & Filtration

Sump

40 gallon breeder

Custom glass baffles (cut at Home Depot)


Filtration Equipment

ReefMat 500 fleece roller

Eshopps 125 skimmer

Refugium with GRO light
Filled with rock atm


Sump Circulation

There is a circulation pump in the sump that runs up to a manifold, which is then plumbed back into each sump chamber.


---

Return Section Equipment

Jebao DCP-4000 DC return pump

400W heater

Hydros water level sensor

Sicce dedicated pump for water changes


The water change plumbing runs through the floor into the basement where it drains.

An electronic valve is used to stop the siphon when draining the system.


---

Basement Mixing Station

The mixing station is located in the basement.

Equipment:

RODI Buddy

100 GPD filter

Two Brute trash cans


Upper Brute:

Stores RODI water

Filled via float valve

Has a spigot

Also feeds the lower container


Lower Brute:

Saltwater mixing container

Mixed with an Iwaki pump


Both containers also have Vivosun pumps installed.

I skipped using a separate ATO container since the RODI Brute serves the same purpose.


---

Water Change System

Water changes are partially automated using Hydros.

Current process:

1. Open electronic valve


2. This disables the water level sensor and allows the sump to drain


3. Once the water level drops, close the valve to stop siphon


4. Activate saltwater pump


5. Refill sump


6. Run return pump briefly


7. Repeat cycle



Salt mix:

Instant Ocean

1.026 salinity

78°F


Future upgrade plan:

Drain water directly from the display tank to simplify the process.



---

Control & Power

The Hydros system currently controls:

Gyre

Wave maker

Various system functions


Some equipment runs through two Hydros 4-outlet power strips.

Critical equipment:

Return pump

Heater


These are plugged into a CyberPower battery backup.

Before next winter I plan to add a generator for extended outages.


---

3D Printed Parts

A few components were custom printed:

Display tank lids

Printed in PETG

cool! I really like the concept on those lids, can you give more info on them? Whats the white I beam for? Im guessing you printed them in sections and they snap together or are glued.

Great job on the scape too

Hey thanks! It was a project lol. I couldn't find any models for a 75 and so I made my own. Each side is printed in six pieces and then the white bar is to stiffen it up and it also rest on the rim of the tank to keep it off the water. They are all glued together with pvc cement. Lots of trial and error and filament lol.
