Here is an excellent and attractive addition to any freshwater tank. The Marimo ball, also known as Moss ball or Japanese moss ball is actually a filamentous green algae (Chlorophyta) found in a number of lakes in the northern hemisphere: Japan, United Kingdom, Russia, Iceland and Northern Europe.

In our effort at keeping algae away from our tanks, algae eaters can be great allies. Here is a short list of some saltwater algae eaters I know. If you know any other fish or invertebrates that should be added to this list or would like to add some information to this list, please use the comment box bellow. Thanks!

DESCRIPTION
TDS checker with measurement range of 0-9990 ppm. From 0-999 ppm, the resolution is in increments of 1ppm. From 1000 to 9990 ppm, the resolution is in increments of 10ppm, indicated by a blinking ‘x10′ …

I just realized I never wrote about that very important aspects of successful fish keeping: water changes. This might be obvious for many of us but it is certainly not for everyone. Yesterday, I received two calls from people looking for an answer to their problems: The first tank wasn’t cycled after 6 months (ho yeah!) and the 2nd had a serious (I mean… SERIOUS!!!) nitrate problem. Two problems that could have been avoided with regular water changes.

I’ve always been curious about new techniques and idea. I can’t resist, I have to try them all. Three years ago, I heard about a simple filtration system that removes nitrates and phosphates from any aquarium (fresh and saltwater) at low cost. Once again, I couldn’t resist and decided to give it a try.
