Read the scoring as a preparation plan
The official CIAC 2026 page identifies growth, color, vitality, and the overall visual effect of aquatic plants as the 60-point Aquatic Plant Condition category. Maintenance Skills account for 30 points and cover information about lighting, CO2, temperature, nutrients, water quality, and algae control. Photography accounts for the remaining 10 points, including close-up plant views and overall composition.
This structure does not make composition irrelevant. The plants still need to work as part of a convincing aquascape. However, it suggests that visual drama should support plant quality rather than conceal poor condition. A simple design filled with vigorous, well-colored plants may be better prepared than a highly elaborate scene showing damaged leaves, algae, or inconsistent growth.
Build plant condition before chasing the final look
Start by identifying what each plant needs to remain healthy in the submitted aquarium. Observe new growth, color, leaf shape, density, and signs of stress instead of judging the tank only from across the room. Remove damaged leaves and trim in a way that encourages the intended shape without repeatedly disturbing plants that are still establishing.
Color should be developed steadily rather than forced through abrupt changes. Keep lighting, CO2, nutrients, temperature, and water quality consistent enough for you to understand how the plants respond. If a plant declines after a change, record what changed and adjust methodically. A controlled routine makes it easier to distinguish a genuine improvement from a short-lived visual effect.
The published rules also state that contestants must provide proof that submitted organisms were raised by themselves. Keep progress photographs and basic cultivation notes as the aquarium develops. Those records can help demonstrate ownership and give you a clearer history of the plants’ condition.
Treat maintenance records as part of the entry
The 30-point maintenance category gives contestants a reason to organize the technical story behind the aquarium. Keep a simple record of lighting settings or schedule, CO2 use, temperature, nutrient routine, water-quality observations, water changes, pruning, and algae-control measures. The goal is not to create impressive-looking paperwork; it is to show that the aquarium is being managed deliberately.
Algae control should be approached as prevention and observation, not as a last-minute cosmetic treatment. Note where algae appears, whether it follows a change in light or feeding, and how the tank responds to cleaning or plant maintenance. Avoid making several major adjustments at once, because that makes the result difficult to interpret and can destabilize the aquarium.
Before submission, review the tank as a system. Check whether the plants are growing evenly, whether older leaves are obscuring newer growth, and whether maintenance has left visible debris or damaged foliage. A final tidy-up should reveal healthy structure rather than hide ongoing problems.
Use photography to prove, not exaggerate
Photography is worth 10 points, so it should communicate the work accurately without becoming the main project. The official rules require a high-resolution, front-view image of the final aquascape; angled photographs or images showing only part of the tank are not acceptable. They also specify one aquascape photo and one photo of the aquascape with the author for each category, with JPEG files between 3 MB and 5 MB and a resolution of at least 300 DPI.
Keep the camera square to the aquarium and make sure the full composition is visible. Clean the glass, remove distracting equipment where practical, and choose lighting that shows plant color without creating glare. Close-up views can help present plant detail where appropriate, but the required final aquascape image should remain an honest front view.
The rules prohibit image editing or modification. Preserve the original high-resolution files because the organizer may compress or resize submitted images and says original files may be used for printing winning works. A careful, natural photograph is safer than an edited image that misrepresents the aquarium.
Plan around the event schedule
The official CIAC page lists the online registration system opening on April 2, a September 15 registration deadline, a September 25 judges’ scoring deadline, and results announced on October 10. It also lists an on-site International Masters Aquascaping Show and invitational tournament on November 12, followed by the CIAC 2026 Award Ceremony on November 13.
Use those milestones to work backward from the submission. Allow time for plants to settle after pruning, for any corrective maintenance to show stable results, and for photography under controlled conditions. Do not leave proof of cultivation or technical notes until the final day. The strongest preparation is a steady process in which plant health, maintenance, and presentation develop together.
The scoring structure ultimately rewards a more durable idea of aquascaping: visual impact matters, but it is most persuasive when it comes from healthy plants and disciplined care. Prepare the aquarium as a living system first, then photograph the result with restraint and accuracy.
