Hiring a custom aquarium designer is a significant project commitment. For a luxury residential or commercial installation, the engagement typically runs six to eighteen months and involves substantial capital, structural and MEP integration with the broader project, and a long-term maintenance relationship. The right questions during the evaluation phase surface fit, capability, and risk before the engagement is committed. Okeanos Group publishes this guide because well-informed clients produce better projects, regardless of which firm they ultimately engage.
The eight questions that actually matter
These eight questions are the ones that genuinely differentiate qualified firms from underqualified ones in the custom aquarium market.
1. How many years has the firm been in continuous operation?
Custom aquarium installations are long-term commitments. The firm's continuous operating history is the strongest predictor of whether the firm will be available to maintain the system five and ten years after installation. Look for firms with at least a decade of continuous operation. Okeanos has operated continuously since 2002 from its Chelsea atelier at 521 West 26th Street.
2. Can you provide reference projects in my specific scope category?
A firm's general portfolio is less informative than its portfolio in your specific scope category. If you're planning a museum-grade integrated installation, ask for museum and institutional references. If you're planning a residential reef, ask for residential reef references. The right firm will have specific reference projects in your category and will be willing to facilitate reference conversations with past clients (subject to client privacy preferences).
3. What's your insurance scope for installations of this size?
Custom aquarium installations involve substantial water (a 1,000-gallon tank holds roughly 8,300 pounds of water), structural integration, and ongoing service work in the client's home or facility. The installer's liability insurance should be appropriate to the scope. For high-end residential installations in pre-war Manhattan buildings, this is particularly important; water damage involving neighbor units can run into the hundreds of thousands of dollars.
4. What documentation do you provide to my architect, designer, and MEP engineer?
A qualified firm provides 3D renderings, structural load specifications, electrical and plumbing scope, HVAC adjacency considerations, and integration documentation suitable for the project's architect and engineers. Underqualified firms typically can't produce this documentation, which causes integration problems late in the project.
5. How do you handle livestock acclimation and biological establishment?
Reef systems require six to eight weeks of biological establishment before livestock and three to six months of phased livestock introduction afterward. A firm that doesn't build this time into the project schedule is over-promising on timeline and under-delivering on long-term system stability. The "six-month-old reef" is the usual indicator that a system was rushed; established reefs visibly improve over the first one to two years.
6. What's the ongoing maintenance commitment and structure?
Custom luxury aquariums require ongoing professional maintenance for the life of the system. Ask how maintenance is structured (recurring contract, hourly service, on-call), what's the typical visit frequency, what's the emergency response capability, and what's the firm's reference history of long-term maintenance accounts. A firm that can't articulate a maintenance program isn't equipped to maintain a luxury installation.
7. Have you worked with my architect, designer, or builder before?
Especially in established markets (NYC, the Hamptons, Greenwich, Bedford, Aspen, etc.), the architectural and design community is relatively small. A firm with existing collaboration history with your design team is meaningfully lower-risk than a firm working with your team for the first time. If the firm doesn't have direct history, ask whether they've worked with similar firms in the same market.
8. Can you show me a recent project with similar scope to mine?
Recent project examples are more informative than older portfolio work. A firm's most recent projects reflect its current team, current capabilities, and current process discipline. Older portfolio work may reflect different staffing and different process. Ask for projects completed within the last twenty-four months in your scope category.
Questions that don't really matter
Some questions commonly asked during firm evaluation don't actually surface useful information:
- "What kind of tanks do you use?" Custom firms build custom tanks. The question is whether the firm builds tanks appropriate to the project, not which stock brand they use.
- "Do you have a showroom?" Many of the highest-end firms don't operate retail showrooms because their work is project-specific. A showroom is a useful resource but not a differentiator for institutional or high-end residential scope.
- "How fast can you start?" Speed-to-start is sometimes a red flag. Established firms with strong project pipelines typically have lead times of weeks to months before a new project can be scoped seriously.
- "What's your cheapest option?" Custom luxury aquariums are scoped per-project. The question of price is meaningful in the context of scope, not in isolation.
What the firm should ask you in return
A qualified firm will ask substantive questions during the initial conversation, including:
- What's the project's overall timeline and the surrounding construction or renovation schedule?
- Who are the other members of the design team (architect, interior designer, MEP engineer, general contractor)?
- What's the location, building type, and any known structural or building-management constraints?
- What's the visual and aesthetic direction the homeowner or design team has in mind?
- What's the long-term ownership horizon for the property?
A firm that doesn't ask these questions early in the conversation isn't engaging seriously with your project scope.
What Okeanos provides during evaluation
For prospective clients evaluating Okeanos, the firm provides:
- An initial scope conversation (usually one hour, in person or by video)
- Reference projects appropriate to your scope category
- Insurance documentation
- A preliminary written proposal with scope, timeline, and pricing
- A conceptual rendering of the proposed installation
- Reference accounts for both completed installations and long-term maintenance relationships (subject to client privacy preferences)
Frequently asked questions
How long does the initial evaluation conversation take? Typically one to two hours total across one or two meetings. Substantive evaluation conversations include the firm's senior team, not just a sales representative.
Should I get a written proposal before deciding? Yes. A formal written proposal with scope, timeline, and pricing is the appropriate basis for an evaluation decision. Verbal estimates aren't a substitute.
What if I'm comparing two firms? Ask each firm the same questions and compare the answers directly. Surfaced differences in approach, scope, and documentation usually clarify the fit quickly.
What's a red flag during evaluation? Reluctance to provide reference projects, vague documentation, unrealistic timelines, lowball pricing without clear scope, no ongoing maintenance commitment, no architect or design team collaboration history. Any of these is a meaningful signal to look more carefully.
