The focus of the blog has recently been on rock pooling a lot more than on my aquarium, as unfortunately it has been in a state of limbo for months now. I received my new LED retrofit kit a while back, but have been caught in the unholy triangle of being busy, hopelessly technically unsavvy and prone to procrastinate. Although the LED kit was solderless (easy), the dimmer to go with it was not (not very easy). I asked my local sparky but he managed to only make it halfway through the installation and I am now waiting for someone else to drop by to help out. I am really curious what the LEDs will look like and desperate to go from the current unlit disgrace in the living room to a nice tank again (especially now I have a chiller as well).
So in the mean time this post about tropical seaweed aquariums I found whilst trawling the internet. Although there are few aquarium blogs, there are many aquarium diaries on forums. Just a couple of those are devoted to seaweed aquariums (for examples see here and here). The first one I found on this thread (not much information on species) is a stunning looking tank mixing corals and seaweeds:
I found a similarly impressive tank on the nano-reef forum, which has a special section on macroalgae, eelgrass and mangroves:Absolutely beautiful seaweeds (follow the link to see many more pictures and a species list). Apparently, there are several aquarium retailers that sell tropical seaweeds; the ones in this aquarium came from LA Reefs and Gulf Coast Ecosystems, which have large collections of many very interesting species. (See for an amazing, unidentified, iridescent seaweed this picture and this video.) Gulf Coast Ecosystems has an especially large collection of seaweeds from Florida with good descriptions of their requirements, see for example this page on the very distinct green alga Acetabularia. It even has a short guide on how to keep seaweeds in the aquarium. After some more browsing, including on the marine plants and macroalgae forum at Reef Central, I found that there were actually quite some suppliers of tropical species, for instance reefs2go, aquacon and reefcleaners. Another stunning tank:
This one is a bit more conventional with many corals and seaweed species that are quite often encountered in ‘normal’ reef tanks such as Caulerpa. Caulerpa species can actually turn into a nuisance as they can grow very fast. Moreover, it can enter the sexual part of its lifecycle causing cloudy water (lots of threads are dedicated to these problems). This aquarium also features a little mangrove seedling, which is often used in sumps (as are green seaweeds such as Caulerpa and Chaetomorpha) to remove nutrients from the water. Looking at these pictures I am almost tempted to go for a tropical aquarium, as it allows both corals and seaweeds. However, I’ll stick to my native beasties that I can collect (and put back) myself, which is half the fun. Perhaps I’ll post another time about eelgrass aquariums. I have seen a bunch of tropical examples but it would in theory be possible to have a cold water seagrass aquarium as well. Hopefully my LEDs will soon be fixed so I can post about my own aquarium instead though.
