Seachem Doser 1.2 is now available on the Play Store.

Major changes include metric support, new products (see below), and an interface redesign with improved material design.

Previously, I was having to resort to reverse-engineering Seachem’s Flash-based dosage calculators in order to obtain dosage calculations. Thankfully, they finally added web-based dose calculators, albeit with some errors/miscalculations on their end at the time of writing this.

Additionally, support for Honeycomb and below has been dropped due to insignificant user distribution and the effort required to provide backwards compatibility. Sorry for the few of you that this may affect.

I’ve just finished moving my website over from WordPress to GitHub Pages. It’s something I’ve been meaning to do for a while now. Despite using WordPress for years, I’ve found it to be rather excessive for my personal needs as far as resource usage and maintenece goes.

Although I never personally had any security issues with WordPress, it’s definitely a high-profile target and switching to static content definitely helps mitigate some attack vectors. Not to mention the inherent load time decrease because of said static content.

Having already used Jekyll/GitHub Pages many times before, the move wasn’t terribly painful. There were a few ‘gotchas’ here and there, but with a little hacking, things were ironed out. I’ll probably post some of those solutions in later posts.

I took advantage of the migration to redesign the site and perform some general maintenece on posts and the like.

Additionally, all comments have been moved to Disqus.

There may still be a few quirks here and there that I haven’t noticed yet, but overall things are working smoothly.

So I’m about 8 months late to posting this. Granted, I’m quite behind on posting a lot of developments (sleep deprivation puns). Anyway, Seachem Doser is an Android app that I developed a while ago that serves as a “dosage/quantity calculator” for various products Seachem offers.

Seachem, for those who don’t know/have lives, is a company that offers various products geared towards maintaining freshwater and marine aquariums. Personally, I use a lot of their products for my high-tech planted aquariums.

They offer calculators on their site that allow you to calculate how much you should dose specific fertilizers, buffers, conditioners, the amount of gravel needed per a specific volume, etc. Sadly, these calculators are all Flash-based. So I decided to make one that’s a bit more flexible. I should note that all of the values for these calculations were pulled from their official calculators, after a bit of reverse-engineering. At first I just made a Windows-based calculator/library that you can find on GitHub. Eventually the issue of convenience took hold and I decided to make it mobile.

As of today, I just updated it to work on tablets and polished things up a bit since I had some free time.

As with the Windows version, the Android version is also open source on GitHub.

If you happen to be somebody who will find it useful, feel free to download it through the Play Store.
