Frequently asked questions
- Do these tools need an account or a payment?
- No. Every tool is free to use, with no registration or login and no limit on how often you use it.
- Are the results authoritative standards?
- No. The glass thickness curve is an empirical fit calibrated against common off-the-shelf tanks, and the water volume and equipment suggestions are estimated with general rules of thumb. Check them against the actual glass grade, workmanship and equipment specifications; the user carries the safety responsibility.
- Can I use them on a phone?
- Yes. The web app has a mobile layout: on small screens the 3D view stays pinned to the top of the page, and parameters and lists switch between tabs.
- In what order should I use them on a new tank?
- Start in the tank designer to fix the dimensions and get the glass cut list and total weight, run the glass thickness calculator to double-check the panes, then use the stocking estimator to decide how many fish, the lighting calculator to pick a fixture and the heater calculator to size the heater. Fertiliser dosing comes after planting, once you can see how the tank responds. Every result links to the neighbouring tools, so following them in order leaves no gap.
