ISTA Powered Surface Skimmer and CO2 Reactor

This dual-purpose ISTA device combines surface skimming and CO2 diffusion in one compact, powered unit for cleaner, healthier planted tanks.

See our guide to CO2 & Bubble Count for dialing in the CO2 side of this dual-purpose unit. Part of the Planted Aquarium Accessories range at IndieFur.

Specifications

Type: powered surface skimmer and in-tank CO₂ reactor

Inlet: self-floating, tracks the water level automatically

Flow: adjustable at the inlet

Outlets: several types supplied, for different tank layouts

Mounting: suction cups

Compatibility

Unlike the passive ISTA skimmers this one has its own impeller, so it does not need a filter to drive it. It doubles as a CO₂ reactor: gas fed into the inlet is chopped by the impeller and spread through the tank.

Connects to any pressurised CO₂ supply on standard tubing.

Safety & Precautions

Unplug the unit at the mains before putting your hands in the tank or opening it up. Water and a live mains connection are the one combination in this hobby that can actually kill you.

Leave a drip loop in the cable — a downward bend below the socket — so water running down the flex drips off the bottom of the loop instead of running into the socket.

Do not run it out of water. Like any impeller pump it is cooled and lubricated by the water it moves.

What's in the Box

The powered skimmer with its impeller, the self-floating intake, the several outlet types and the suction cups. CO₂ tubing, a check valve and the gas supply are not included.
