Hello. travis recommended me to this forum and I can say that I am impressed by what I see so far. I look forward to contributing during my time here.
A little background on my experience first: I've been working with planted freshwater aquariums for over three years now (Aug 03) and have been working with saltwater/reef aquariums for almost two years (Jan 05). I know it's not a long time and I'm not much one for advice, but I'm a very fast learner and I really like this hobby and the things you can do with it. Plus its nice to look at your work and just stay interested in all the life that's inside of them.
Planted FW: I've had a few 10G tanks, one 2.5G tank, and one 20G tank. When I heard about CO2, my first method was by yeast and the old Hagen bubble ladder with a HOB filter (I know, I know, bad combo). I increased light, CO2 and nutrients to levels you wouldn't believe and forced my plants to do things normal people shouldn't do--hard to keep algae controlled. Then I upgraded to a canister filter with my 20G setup and added a pH controller with a pressurized CO2 setup for pretty good growth under 65W bulbs.
Reef SW: I've had a 50G tank that started out ok, had some bumps in the road, smoothed those out and starting doing really well for a while. Then I went through some bad experiences with a cross-country move and things went downhill quickly as the tank went through another cycle. I lost quite a few corals and fish before I can find someone to take them. Then I restarted the tank. Almost a year later, I decided to sell the equipment down to a much smaller 10G system. From there I've been rocking and rolling with this little guy. Easy maintenance, easy to move, kinda hard to keep clean, but fun nonetheless. Its skimmerless with high flow and 96W of light with zoanthids, ricordeas and hair algae .
Now this is what I want to do. I'd like to start a saltwater macroalgae tank in a 10G format and specialize more on simple, easy to keep species of macroalgae. I've never dealt with macroalgae before so I'm brand new to this. As far as lighting, filtration, water movement, nutrient levels and general maintenance are required on a tank this size? I have some 13w bulbs, ballasts and sockets from my previous tanks, could these be used? And would a HOB filter with some bio-media for KNO3 production be acceptable? What kind of substrate should I incorporate? Would Seagrasses be able live in this type of environment or will the depth of a 10G be too shallow?
Thanks ahead of time and hopefully I can learn a lot of good information. And Tom Barr, you are awesome!
