A valued re**er has built a web app that demonstrates flow in your tank. You input your tanks dimensions, power heads, rock work and it shows you how flow moves around your tank.
Secondly, he's added a section which shows PAR across your own tank, you can add your light to your tank which is already set up and see what the PAR would roughly measure at every point in your tank.
There are also the classic features of a aquarists app such as parameters log and overall tank health.
He would love some feedback so comment here if you access it. While the app is in development itβs completely free as he just wants feedback from users.
