About us. Our 9 year history

GoToGarden started in 2017 out of personal frustration. Our founder was a hobby grower who spent hours navigating online shops that felt built by people who had never touched a plant — cluttered layouts, vague product descriptions, no real guidance on what to actually buy or why. He knew there had to be a better way.

Why do my pH and EC meters need replacement parts?

Over time, electrodes and pump components can degrade, leading to inaccurate readings or system failures. This collection addresses the need for precise monitoring and reliable dosing by providing essential replacement parts. Ensuring your equipment functions optimally prevents common cultivation issues such as nutrient imbalances or incorrect pH levels, which can stunt growth or harm plants. For example, a worn EC probe can misread nutrient concentrations, leading to over or underfeeding, impacting crop health and yield. Maintaining these parts is crucial for consistency across all growing stages, from seedlings to flowering.

Explore essential replacement parts for your grow

This collection offers a comprehensive range of spare parts for both Aqua Master Tools and Milwaukee monitoring and dosing systems.

Aqua Master Tools vs. Milwaukee: precision for every need

Aqua Master Tools offers robust and reliable components, often focusing on system integration for their C800 PRO controllers, ideal for growers seeking comprehensive automation. Milwaukee, a recognised brand in water quality testing, provides high-precision electrodes and meters for growers who prioritize accurate, real-time parameter monitoring across various applications. Both brands offer dependable replacement parts, with Aqua Master Tools excelling in pump and plumbing solutions for automated systems, while Milwaukee leads in specialized electrode technology for precise pH and EC readings.

Navigating your component replacement decision

Growers needing to replace a faulty electrode for pH measurement in nutrient solutions should first identify their meter model, such as Milwaukee pH51 /products/milwaukee-ma73600-elektroda-pro-ph-metr-ph51 or Aqua Master Tools P700 PRO2 /products/aqua-master-tools-nahradni-ph-elektroda-pro-kombinovany-ph-metr-p700-pro2. If an EC sensor is failing, check for compatible Milwaukee EC60 /products/milwaukee-mi59p-elektroda-pro-ec-metr-ec60 or Aqua Master Tools E300 PRO /products/aqua-master-tools-nahradni-elektroda-pro-ec-metr-e300-pro-20 replacements. For automated dosing with the C800 PRO system, consider replacing peristaltic pump units /products/aqua-master-tools-c20-pump-unit-2x-peristalticke-cerpadlo-ziviny-c800-pro, /products/aqua-master-tools-c10-pump-unit-1x-peristalticke-cerpadlo-phziviny-c800-pro, /products/aqua-master-tools-c30-pump-unit-3x-peristalticke-cerpadlo-ziviny-c800-pro or ensuring proper plumbing with tapping saddles /products/aqua-master-tools-tapping-saddle-40-mm-12-c800-pro, /products/aqua-master-tools-tapping-saddle-40-mm-34-c800-pro, /products/aqua-master-tools-tapping-saddle-50-mm-34-c800-pro, /products/aqua-master-tools-tapping-saddle-50-mm-12-c800-pro and dosing tubing /products/aqua-master-tools-davkovaci-hadicka-pro-c-series-10-m-c800-pro, /products/aqua-master-tools-davkovaci-hadicka-pro-c-series-5-m-c800-pro. If your Milwaukee meter requires calibration and cleaning, the service kit /products/milwaukee-servisni-kit-pro-ph-a-ec-metry is an excellent choice. For comprehensive monitoring, the Milwaukee MI60P probe /products/milwaukee-mi60p-elektroda-pro-ph-ectds-teplota-metr-mw804 offers pH, EC/TDS, and temperature readings.

Frequently Asked Questions

My Aqua Master Tools pH meter P50 Pro is giving inconsistent readings. What should I do?

You likely need to replace the pH electrode. The Aqua Master Tools Náhradní elektroda pro pH metr P50 PRO 2.0 [5] is designed to ensure accurate pH measurement of water and nutrient solutions, restoring your meter's reliability.

My Milwaukee EC monitor MC310 is showing erratic conductivity values. What is the most likely cause?

An aging or damaged EC electrode is the usual culprit. The replacement electrode for the Milwaukee EC monitor MC310 [14] will restore accurate conductivity readings necessary for optimal plant growth.

I am setting up an automated dosing system with Aqua Master Tools C800 PRO. What parts do I need to connect plumbing?

You will need tapping saddles such as the 40mm 1/2" [20] or 40mm 3/4" [32], and appropriate dosing tubing like the 10-meter [22] or 5-meter [40] options. An injection valve [29] may also be required for precise nutrient delivery.
