thanks for the help. Yeah only see 32 gallons build but not much 14 gal but I’ll keep looking.You may want to look at the Sicce 1.0 or similar for the pump. Also, take a look at the build thread section and search for other bio-cubes for inspiration. Good luck with whatever you choose!
Thanks you so much. This was very helpful on getting this started.I recently had to replace my return pump on my 14g biocube. I picked up a cheap one on Amazon:
DOMICA 220 GPH Ultra Quiet Fountain Pump, Small Submersible Pump (15W 800L/H) for Pond, Water Feature, Aquariums, Hydroponics, Indoor or Outdoor Fountain https://a.co/d/9wuhMot
Only $15. It's a little stronger than the original pump.
Here is the original pump:

Also I'm using this wave maker:
hygger Mini Wave Maker Magnetic DC Powerhead with LED Display Controller for Saltwater Tank, 1600 GPH Aquarium Water Circulation Pump 5 to 30 Gallon, Black https://a.co/d/iR89Mt4
I have bioballs in the very bottom of the second chamber and I only run filter floss through the first chamber with the heater. I also have ATO sensor in return chamber at the max water line.
Best of luck with your new tank!
Thank you. How about filtration?I run a Tunze 1073.008 on my 20g and next 15g. Great pump for the money.
In my 20 I run 3 baskets, 2 eheim substrate pro and 1 matrix.Thank you. How about filtration?

Thats what I'm doing now before buying all these thingAlso, I’m sure you’re more than aware but if you picked up a used tank I would definitely run a water holding test on it first. Fill it up with water and watch for leaks before you stock anything
Thanks I will check it outFor my Biocube 32g , I based much of my filtration on the YouTube video: Coralife Biocube Basics, simple filter modifications. I hope it helps.
Hello, I have the 14gl bio cube and intrigued by this divider you mentioned… As in where it’s at and how it works?I’ve tried a lot of mods, went rimless, built a custom hood for my AI 16HD. Best mod I did was 14g intank divider. I tried to make my own DIY for like 6 months and it never worked lol. Finally pulled the trigger.
