Update on Algae scraper
I have posted here some questions about scratches on the glass, potentially by the ceramic blade but more likely from inappropriate handling of the scraper (
https://www.bareefers.org/forum/thr...g-for-advice-tunze-long-ceramic-blades.35891/)
Some of the great advice I received was the following:
- Consider using a ‘mighty magnet’ instead of the Tunze.
- Do not leave the scraper in the tank after cleaning (I never thought about this).
- Ceramic blades should not be used on its own but only installed on a Tunze scraper.
- Specific instructions by Tunze to only use the scraper length wise, so that sound/debris can fall out easier (another aspect I would have not thought of)
So clearly, it is most likely that my 2-3 scratches on the glass came from wrongly handling the scraper vs the ceramic blades or the Tunze itself.
Still, looked into the Mighty Magnet before and now bought it. And for the first time read the instructions

that came with the scraper. Now the price is an issue but in hindsight, I tried different scrapers before and had I just bought this one, it would be similar in price or potentially cheaper. But my main objective is to minimize or eliminate (unlikely) the risk of additional scratches, and this I believe was worth the investment. I also purchased the dozer bags and the cutter bags, but have only used the dozer so far.
My initial reflection is that it is a bit more involved using it, it does feel effective and safer, but it needs to be cleaned after each use, dried and put back into the box it came with (ideally). So it is a bit of a process now vs just doing some quick glass cleaning.
I have bought following type of scraper for my 15 mm glass:
Add 1/4″ (.65cm) to your aquarium glass thickness when using our Algae dozers to maximize their efficiency. You can always reduce the strength of our magnets with one of our spacers.
