20g High setup - first saltwater tank

[tang daddy]

Ahh the joys of having the first reef, I remember way back when I saw my first sponge, pods and stuff sending feelers out the live rock....amazed with all the life, almost gives you that feeling of getting your drivers license and buying your first car to go for a spin. I couldn't wait I think it was about 3 days when I added some Zoas and it was a down hill snowball effect after that.

I was going to say if you added a hang on filter with surface skimmer attachment it would get rid of the nutrients on the surface but you already solved that problem.

There are many options for a led reef light on eBay, do some research but safe to say for around $100 you can get a decent one. Try to find an led with more blue than white, or if you are handy you can build your own light!

Small reef fish like bangai, chromis, clown, fire fish and even gobies would be really cool for this size tank.... once established 5g water changes per week would be ideal for this size tank.

What skimmer are you running again?
