It’s been over a month since I began my opae ‘ula tanks. I now have four set up in different places in the apartment. A common element in all four is a sponge filter. In three, I’ve also added a pile of coral rocks on one end.
The original 5-gallon Fluval Chi has undergone some changes. (See the original.) I removed the kit filter-lighting system and added a small sponge filter. I moved the aquarium to the right side of the long desk, but it’s still receiving a lot of indirect sunlight from the south-facing louvered window.
Update 10/30/14: Fluval Chi — concerned about the salt water evaporation in a room full of electronic equipment, I decided to cover the large opening on the top to reduce the amount. I laid a rectangular piece of glass over the opening, but it drew the evaporation to the edges and over the side, so that didn’t work. I finally resorted to the old standby, duct tape, to cover the opening. It’s ugly, but it seems to be working — sorta. Salt crystals are beginning to accumulate along the edges of the tape. I’ll have to find a better solution.
