I had a salt tank for a short time ~25 years ago (as a teenager). At the time I read Martin A. Moe's handbook and reference. About a year and a half ago I started a project to try keeping sea squirts in my lab. They were difficult to keep and the tank crashed twice. I decided to bring it home and set it up for fun and to teach my self a bit more about keeping marine invertebrates. Looking forward to learning all about corals and maybe keeping a stray sponge or sea squirt in time. Looking for low maintenance but pretty in the short term while I get my sea legs.

20180622 set up aquarium.
20180628 changed to RO/DI water from LFS.
Is 2ppm phosphate from tap water or dead algae from the sea squirt tank? Is it a problem? Yes replaced water w/ RO/DI or MilliQ
Have Current USA Satellite Freshwater LED, 7.5W $59, What do I need for soft coral and mushrooms and zooanthids?
Is AquaMaxx Prism LED Light Fixture, 48W, $149 the best option? No, they have a supply problem.

returned Goby (had ich like fungus), got pistol shrimp and watchman goby, $20.
tested nitrates at 10ppm?!. Daily 0.25L water changes must be keeping up.
water tested 0 ppm nitrates for second week since daily water changes 0.25L.
Probably due to growth of small amount of macro algae in corner of tank.
GSP is doing great but bumblebee snails are nesting in it?!
added Acan (micromussa) lordensis. Likes brine shrimp
nitrates steady at zero.
added Fire shrimp.
0 ppm NO3.
Acan seems to be adding polyps (2 small ones).

made first 10 gallons of 0 TDS water.
tested water, everything looks fine, Ca and dKH seem low.
cleaned protein skimmer (seems to have stopped working).
ATO clogged up with algae and quit working. Should probably clean every six months or so.
