The filter is a semi-DIY internal filter, with a big sponge material around the entire outside (including where the water is sucked in) to act as the filter media. During the last cleaning, the filter was full of particles and dirt (including the black stuff), and quite a bit was accidentally...

Alright, thanks! Is it safe to take care of that with everything still in there? Seeing how the last filter cleaning killed multiple fish, I'm rather wary of starting to mix stuff around too much. It does seem to be going better the past few days, though. Several of the fish have been moved to...

That depends, how thorough a cleaning are we talking about? The top layer (what is reachable of it) is cleaned once a week, during water changes. The bottom layer(s) and especially stuff below various rocks, caves and plants, on the other hand, are probably almost never cleaned.

Hmm, that sounds weird. I looked through the log, and nitrate (NO3) has tested as 0 every time this year, perhaps 8-9 times or so total. There haven't been many issues prior to the past few weeks, though. I assume water conditioner is the stuff that removes chlorine/chloramines, copper and...

First off, I apologize if my terminology is off. Please ask for clarification if you need it to understand something. English is not my native language, and I virtually never read about aquarium stuff in English, so I had to translate many aquarium/fish-specific terms! I'm helping take care of...

Hi! :) I need some advice regarding the resealing of a 520 liter (138 gallon) freshwater aquarium. All the silicone from the bottom and sides has been very thoroughly removed, and the glass cleaned with isopropyl alcohol. However, getting the top edge clean is next to impossible, at least with...
