Closed System Colonic.

A small rectal speculum is inserted and connects to a closed loop of medical-grade tubing. The device — typically a Dotolo, Aquanet, or similar unit — controls water temperature (usually 98°F to 103°F), pressure (typically under 2 psi), and flow. The practitioner sits beside the client, monitors waste through a clear viewing tube, and adjusts the fill-and-release cycle based on what they see. The client remains in one position throughout, typically left-side or supine.

Closed-system devices allow a trained practitioner to see, in real time, what is leaving the colon. This changes the session from an autonomous release into a diagnostic-adjacent interaction: the practitioner can identify fermentation, parasites (rare), mucus plaques, or unusual coloration, and can adjust the protocol accordingly. Closed systems also deliver higher therapeutic pressure safely, which can reach impacted matter in the transverse and ascending colon that open systems sometimes cannot.

Closed-system colonic devices (Dotolo EC-2000, Aquanet EC-2000, Angel of Water, LIBBE) are registered with the FDA as Class II medical devices, which means the manufacturer has submitted a 510(k) clearance and the device is subject to manufacturing quality controls. This does not mean the FDA has endorsed colonic hydrotherapy as a medical treatment — it means the devices used for it meet manufacturing standards. Open-system tables are not subject to the same classification.

45 to 60 minutes of hydrotherapy, plus intake and clean-up. Because the practitioner is present throughout, closed-system sessions often run slightly longer than open sessions, and first appointments are typically 90 to 105 minutes total for intake, session, and post-session guidance.

$90 to $180 per session in most US cities, with clinical practices at the high end ($150 to $250 for experienced practitioners in major cities). Higher pricing reflects the practitioner's full presence and higher device cost. Insurance coverage is extremely rare for colonic hydrotherapy in any jurisdiction, so everything is out of pocket regardless of the system.

Is this a FDA-registered Class II device, and which model? What is your disposable speculum protocol — single-use, sterilized, or sanitized? Are you I-ACT certified, and what level? Do you have specific training on the device you're using? How do you handle clients with a medical contraindication that only shows up during the session (rectal bleeding, severe pain, blood pressure drop)?
