So within the past 2 months I bought a saltwater tank setup. I've had freshwater for 6 years (since I was 16) and I wanted to upgrade. I went to Elmers Aquarium Store in Monroeville PA. I'm always very impressed with that place, and their knowledgeable staff. So telling the kid I don't want to spend over 2k, he helps me get together a nice 26g tank with almost everything I need. Now I've added live rock, and little Nerite snails to enjoy the tank while I go on vacation. (I didn't want to have anyone babysit brand new fish). I'm more or less posting pictures and the like to get opinions. I have a 26g bow front tank, aragonite white reef sand, Coralite hood/light fixture including Actinic, bright 10,000k, and blue led lights (for show). Koralia power head, a 90g rated mechanical filter and a bunch of other stuff. (See pictures). Now, I was told to also buy a protein skimmer, which I always planned on doing. However, now I'm being told that you can get away without a mechanical filter if you have a protein skimmer. Is this true? Also, I have a slight diatom problem which I've been treating (siphoning out the brown dustings on the substrate). Now I'm getting a light gray dusting on the sandbed. Any advice for a SW newbie? I also eventually plan on getting corals, thus the 200$ light fixture.
