I had this tank running for years, back in the late 2010s. Sat for about 7 years, and now it’s back! Like a zombie. Took a crack at creating my own stand cause the Coralife one is cheesy imo. Coralife 32g Biocube (Tank started 6/28/26) Lighting NanoBox Retro LED upgrade w/Bluefish controller...

I'm considering creating a sump out of a 40G breeder, but they don't seem to be around anymore. Petsmart doesn't have them online at all and Petco is out of stock across southern California. Been out of the hobby a couple years and getting back in. Are they no longer in fashion?

I recently have bought a Neptune Apex and have made some DIY compatible solenoid valves and posted the .stl files to Cults3d if anyone is interested in making one for yourself. They are a direct replacement for the SV-1. As far as I can tell the solenoid body is the same used on the SV-1 so the...

Hello Everyone! It's been 2 years of being into the hobby with a whole bunch of ups and downs, but one thing I still haven't really been able to get a solid grasp/stance/opinion on is sumps. I know they're used as a replacement for typical filtration (like cannister filters/HOBs), but I don't...

The short and skinny: it works! Scroll down for instructions, the first part is me waxing philosophically I've been working on my first build and have been trying to strike a nice balance between affordability (whatever that means in this hobby), reliability, and most importantly -...

Recently picked up a large ~200ish gallon Waterbox Peninsula for cheap, came into it knowing it needed a full reseal. Has a small bubble in the upper front corner seam; both interior and exterior faces of the seam are intact, bubble is approximately 0.2"×3" (half above waterline, half below)...

I wanted to start this discussion now because I have some ideas that I would like to bounce off some folks before I start cutting lumber. I have a 8x2x2 acrylic tank with dual overflows. I’m going to build the stand, which by itself isn’t very complicated. This is where it gets tricky. I am...

I would like to make my own frag rack. I have done many DIY projects myself however, I am pretty paranoid about magnets rusting in my tank. I am writing this post to see if anyone has any advice and actual experience of the proper way to seal magnets so they do not rust and leach into the tank...

Small startup out of Texas thinking about an aquarium controller and want to gut-check before I waste a few months on it. Idea is a small touchscreen with temp/pH/TDS probes, a smart 4-outlet power bar to switch heater/pump/light, and a mobile app to check on it from anywhere. No subscription...

I've been running Noo-Psyche K7 Mini lamps for a while and wanted proper schedule control without relying on the app, so I built a small open-source controller that runs 24/7 on a £3 ($4) ESP32 board. Thought it might be useful to others here. What it does A tiny ESP32-S3 board sits on your...

I’m pretty new to all of this but hopefully I’m on the right track. I started in the Hobby in November 2025 with a Cobalt AIO 45g cube. Immediately fell for it and wanted to go bigger. I have put together some pieces from marketplace but wanted to see about my plumbing and/or plans for plumbing...

Hello everyone, Although I have been looking around R2R a lot, this is my first post here so let me know if doing something wrong... First of all I have not set up any aquarium by myself before, however have gotten to see and help with quite a few setups as my dad had multiple saltwater and...

Hello everyone. I have a mediterranean aquarium (300L, 250 Dt and 50L sump). I am currently running my two lominie pixie 150w reef leds, which i unfortunately cannot use their app for sunset sunrise, timer, color etc, so they run full spectrum full intensity all the time, and are being turned on...

Hi everyone — I’m building a DIY reef controller using an ESP32-S3 and could use some guidance from anyone with electrical/analog experience. pH measurement (Main Question) I’m trying to design a safe, robust pH input circuit that interfaces cleanly with the ESP32-S3 ADC, but I’m a bit lost on...

I’m wanting to know what I can do with my overflow box it’s starting to leak. Cut it out replace them? Is there a sealant that could hold it? I know they dnt make the parts anymore for this gen.

Hello everyone! Every time amino acids come up on Reef2Reef a small controversy arises. Some people find them beneficial and worth the cost, while others question their value or even consider them harmful. There are plenty of commercially available products: Red Sea ReefEnergy AB+, Fauna Marin...

one of the things i love about reefing is the technical challenges it presents and with that the mind gets working on new ideas and often overthinkin, now i know this isnt the fist time this has been done but i built one of the very first aquarium chillers back in 1990 for my 300lt reef system...

Hello, looking for files for anyone that has cut or created baffles with a water jet or printed them before. I have free material and access to a big printer and water jet. Also does anyone have input wether 316 stainless would be aquarium safe….i am absolutely not doing it but my brother is...

Hello fellow hobbyists, I’ve started building a DIY Reef Aquarium Monitor using an ESP32-S3 Waveshare display board, and I’d love to get your inputs and suggestions. Here are the main features I’ve planned so far: Temperature monitoring and control pH monitoring Salinity monitoring ATO (Auto...

Sold selling my 180 gallon sump. was originally used under another 180g reef tank. All glass partitions inside were custom cut and then siliconed into place. Far end served as the ATO reservoir. No leaks, no cracks anywhere. This is a MONSTER sump setup. Partitions are glass, not acrylic...

I currently have a Marineland 55 for Freshwater which I know is completely Tempered and a Aqueon 29 for saltwater which has no tempered panels and I also drilled bulkheads in. I am relocating both tanks after the wife had me renovate the room they were in. To save space I am building a stand to...

I have this as a rough design for what I want to do to a 40 gallon breeder to make it an aio frag tank/grow out tank/ secondary reef tank. Not sure which direction I’m going to go with it at the moment but I wanted any others insight on if this design seems like a good one and might work and if...

I’m trying to make a floating rock shelf for my reef tank and I’m not sure what materials would be best. My tank is 24” L 14” W so not big but I want the entire reef elevated about 1 1/2 to 2 inches above the sand with nothing touching the sand to support it Should I use cast acrylic or...

Hi all sorry for the long post, I have a Cade 1500 S2 that I purchased second-hand from fakebook around a year ago to upgrade from a Waterbox 90.1. For the first 9 or so months I have had no issues with the tank, and transferred the majority of my live coral and corals across to the larger...
