You know, after thirty-two years of dealing with life-and-death situations in the ER, I thought arranging some rocks in a saltwater tank would be the easy part of retirement. Ha. My first attempt at reef aquascaping was like trying to perform surgery with oven mitts – technically I had all the right pieces, but I had no idea what I was actually doing.
I’d gotten pretty comfortable with my freshwater planted tanks, figured saltwater couldn’t be that different. Wrong on so many levels. Bought this gorgeous pile of live rock from a guy who swore it came from his established reef system, spent an entire Saturday afternoon arranging it into what I was convinced looked like something straight out of a nature documentary. My husband even complimented it, said it looked “very artistic.” Should’ve been my first warning sign – he calls everything artistic when he doesn’t want to hurt my feelings.
The problems started showing up about two weeks after I added my first corals. These weren’t cheap corals either – I’d splurged on some pieces that cost more than I used to spend on groceries in a week. But instead of thriving, they started looking… well, sick. Colors fading, polyps staying closed, that general appearance of things that aren’t happy with their living situation. I’d seen that look plenty of times in patients, just never in sea creatures.
Turns out I’d created what’s basically the underwater equivalent of a medical emergency. All those beautiful caves and overhangs I was so proud of? They were dead zones where water wasn’t moving. Detritus was accumulating, oxygen levels were dropping, and my poor corals were essentially suffocating in their own waste. It was like designing a hospital room with no ventilation system – looks great until people actually have to live there.
My granddaughter was visiting when I finally admitted defeat and started tearing the whole thing apart. She’s fourteen now and has this way of cutting straight to the point that reminds me of some of my favorite charge nurses. “Grandma Elena,” she said, watching me pull rocks out, “didn’t you say you researched freshwater plants for like three months before setting up your first planted tank?” Ouch. Kid had a point.
So I started over, this time actually doing my homework. Read everything I could find about water flow patterns, watched videos of people testing current movement with food coloring, joined forums where reef keepers discussed flow dynamics like they were planning spacecraft trajectories. Discovered there’s actual science behind rock placement – who knew?
The key insight, which seems obvious now but completely escaped me initially, is that water movement is literally life or death for corals. They’re not plants – they can’t photosynthesize their way out of low-flow situations. They need constant current to bring them food and carry away waste. Every cave needs at least two openings. Every overhang needs flow underneath. It’s like the basic principles of good hospital room design, just underwater.
My second attempt took twice as long because I kept testing flow patterns as I built. Got myself a cheap powerhead and some food coloring, spent hours watching how water moved through different configurations. My husband thought I’d lost my mind, sitting there with my face pressed to the glass, dropping blue dye and taking notes. But it worked – I could actually see where water was moving and where it wasn’t.
The lighting situation was another learning curve I hadn’t anticipated. In my planted freshwater tanks, more light is generally better for the plants. Reef corals are way more complicated. Some want intense light, others prefer shadowy spots, and your rock structure determines who lives where. I had to think vertically – bright, high-flow areas up top for the demanding corals, gentler, dimmer zones lower down for the more delicate species.
Weight became an issue I never saw coming. Live rock is heavy. Really heavy once it’s water-logged and supporting growing corals. I learned this when a carefully balanced arch I’d created came crashing down one morning, taking out two expensive coral colonies and scaring my clownfish half to death. Now I use reef-safe epoxy to reinforce anything that looks even slightly questionable. Better safe than sorry, and expensive.
The biological warfare aspect of coral placement was fascinating from a nursing perspective – it’s like managing patients with incompatible medications. Euphyllia corals extend these long sweeper tentacles at night that can damage neighbors inches away. Some species release toxins into the water to inhibit nearby competitors. Others grow so fast they’ll literally overtake and smother slower-growing neighbors. You’re essentially doing community planning for creatures that want to kill each other.
I started sketching coral placement plans on paper before buying anything, treating it like care plans I used to write for complex patients. What does this coral need? What does it produce that might harm others? How much space will it need in six months? A year? It’s surprisingly similar to anticipating how a patient’s condition might change over time and planning accordingly.
Maintenance access was something I figured out the hard way. Created this beautiful cave system that looked amazing but was impossible to clean. Detritus would accumulate in the back corners, dead spots I couldn’t reach with any standard aquarium tool. Eventually had to partially dismantle it just to perform basic maintenance. Now I design with cleaning in mind – if I can’t reach it, I don’t build it.

The most rewarding part has been watching the whole system mature over months and years. What started as bare rock arrangements has become this living, breathing ecosystem. Coralline algae spreads pink and purple across the rocks. Corals grow and change color. Fish establish territories and daily routines. It’s like watching a small city develop its own character and culture.
My current 90-gallon reef has been running for almost three years now, and it looks completely different from when I first set it up. The original coral frags have grown into substantial colonies. Some pieces I thought would stay small have become dominant features. Others that I expected to take over stayed compact and well-behaved. It’s taught me patience in a way that my high-stress nursing career never allowed – sometimes you just have to let things develop at their own pace.
The whole experience has reminded me that expertise in one area doesn’t automatically transfer to another, even when there are similarities. My medical background helped with understanding water chemistry and recognizing signs of stress in livestock, but the design and flow dynamics required completely new skills. At 65, I’m still learning new things, still making mistakes, still figuring out better ways to create these little underwater worlds.
