Our aquariums such as the 40oz Micro Tank are built ready to run, meaning there is no extra gear or upgrades required. Every tank comes thoughtfully designed with built-in filtration, evaporation-control lids, and the essentials you need to start your saltwater or freshwater setup right away. But while you don’t need additional equipment, the right accessories can make maintenance easier, boost convenience, and elevate your overall experience. Here are our top five add-ons that can take your desktop aquarium to the next level.
1. Filter Roller
Our compact Filter Roller is a game‑changer for desktop aquariums. It removes fine particulates before they break down, reducing maintenance and improving clarity. This means calmer biofiltration, fewer manual cleanings, and visibly healthier water.
The Filter Roller comes ready to install and each roll lasts 3-6 months, reducing maintenance time and cost. *Currently available for our 1 Gallon Small-In-One and 5 Gallon Small-In-One & 4 Gallon Lagoon.
2. Temperature Probe
Precise temperature control is crucial in small systems. A dedicated Temperature Probe allows you to monitor temperature in real time, triggering alerts before things go out of range. It’s peace‑of‑mind in real time.
3. Auto Top Off (ATO) System
It's important to pay close attention to salinity in small tanks. With our polycarbonate lids and maintenance routine, topping off your aquarium is a simple task. However, our Micro Auto Top Off can make it even easier. Pair it with our ATO Water Container.
4. Heater
If you keep your house below 70° or live in an especially cold environment, you may need to add a heater.
Our heaters feature sensitive thermostats and slim form factors, ensuring stable temperatures with minimal footprint. Ideal for sensitive livestock like corals and small fish where every degree counts.
5. Cooling Kit
Live in a warm environment? Or just prepping for summer? Our Cooling Kit uses efficient fans and thermal sensors to keep your water within a safe band. Think of it as air‑conditioning for your aquarium setup: consistent, quiet, and essential in warmer rooms.
Nutritional Support with Benepets Coral Food
While we focus on hardware, nutrition is equally important. Products like Benepets coral food support a thriving aquarium biome. As the company says, “Our whole‑biome foods deliver the essential nutrients to help corals, fish, and even beneficial bacteria get the nutrients they need to thrive without compromising water quality.” Blend their nutrient‑rich feeds with your PNW Custom setup to foster healthy growth without clouding or degrading water.
Installation Tips & Best Practices
Pair the Filter Roller with routine partial water changes and RODI water.
Ensure that your ATO reservoir is filled with high‑quality water (RODI) to avoid introducing impurities.
Start with small amounts of Benepets coral food, gradually adjusting feeding as you monitor water quality.
