Hi Ryan, welcome.
I have a 30g too and have had much success with it.
I use a Coralife Aqualight with (2) 36w Power Compacts. Once is True Actinic 03, the other is a 10K daylight.
I keep a handful of small fish and inverts (shrimps, crabs, snails).
I also keep 3 frogspawn corals, a torch coral, lettuce coral and bubble coral. Most LPS can be housed in your 30g.
I had the biocube skimmer......for about 1 1/2 days...
I found it to be very horrible (in my opinion).
I replaced it with a HOB skimmer from Octopus, I would recommend this to anyone. Once I put it in, my water quality changed 100%. Everything looked better in the tank, I was getting tons of skimmate from it and purple Coraline algae started to grow.It works with an airstone and didn't collect much. It also took up valuable tanks space and the stone would have to be replaced often. I use the
HB-100F.
I also use a Koralia 1 for water movement in the tank.
I run an Eheim Ecco canister filter as well. I don't use the Eheim substrate in the filter, I replaced it with a nitrate absorbing media called
Denitrate.
I didn't think it would do anything, but to my surprise, my consistant 20ppm nitrate level was reduced to 5-10ppm within 1 month.
The Eheim also creates another direction of flow from the return line.
Good luck.....keep us all updated.
