Hi everyone... I thought I would share my 28g Nano Cube HQI build with you. I purchased it from Foster & Smith after Christmas while they were still on sale. I've added a chiller, refugium, MP10, and upgraded the pumps and lighting. The substrate is 20lbs of CaribSea Ocean Direct Caribbean Live Fine Oolite Sand, and about 22lbs of Florida Reef Rock from ReefCleaners. The rock-work was created using several pieces of rock puttied together onto a heavy rock base. The sump area and refugium each have about 2lbs of rock rubble. I hope you enjoy this running log of my efforts and look forward to your comments, both good and bad!

Change Log:

  • 2011 May 23 - Mr. Coral - Purchased 13 Zoa and Paly Frags and 2 Free Maxi Mini Anemones
  • 2011 May 20 - Foster & Smith - Purchased Brightwell Lugol's, Tech-i, Reef Plus for the arriving corals, MJ 400 PRO and Pre-Filter. I need more water movement in the refugium to limit Cyanobacteria growth, but not more flow, so the powerhead will go in the refugium itself.
  • 2011 May 20 - Lowered Iron dosing to 15 drops MWF. Still dosing C-Balance 2 to push Alkalinity to 11 dKH.
  • 2011 May 15 - Began dosing Kent Tech-M Magnesium to bump up the Magnesium level from 1230 mg/L to 1300 mg/L
  • 2011 May 10 - First algae outbreak. It's ALL Ulva! No hair algae, no diatoms, just Ulva - everywhere. I attribute this to the iron dosing of 15 drops every day.
  • 2011 May 7 - Began dosing C-Balance 2 to increase Alkalinity, and Brightwell Ferrion Liquid Iron.
  • 2011 May 5 - Installed bare-bottom refugium.

Here are more images of the initial rock work from April 2011. The Florida Reef Rock is great to work with.

Here is how the stand internals, tank wiring and plumbing look before and after the refugium addition.

Note the use of the long sponges in the return chambers to prevent microbubbles

The chiller

Pumps on the left, lighting on the right. That's a Coralife dual power center timer on the right - they're junk but do the job for now.

The clean up crew arrived along with macros. Here are some shots of that.

Big clumps of macros, and a few snails

John at ReefCleaners give pretty generous portions of snails!

The Pom Pom Crab doesn't come out too often... He does come out every evening when I feed Rod's Reef Original though. Even the snails come running for that!

Ulva everywhere! I've not had any diatoms or hair algae (knock on wood), and when I started dosing iron, the Ulva just exploded.

An unknown isopod. It doesn't appear to be bad. I found it last night, and it has just been eating detritis. Moves very slow. It appears to be female based on various texts and online images. Any thoughts?
