Hello,
This is my first thread, hopefully it works.
I'm kind of a noob at sw, I have successfully ran a 20H for a little over a year now, no fish mortalities. I've kept fw for about 10 years.
I have started to plan (and save money) for a new 90 gallon AGA, probably within the next few months. My 20g is starting to get full.

I am going to build my own stand and hood and have started preliminary drawings in cad for them, will post those later.
For lighting I will probably go with 2 250 watt 10,000k MH and 2 actinic/2 50/50 65 watt pc's, and building a moon light with blue and white leds, 60 or so. Does the lighting sound fine? I am going to keep mostly sps a few lps and softies.
I want to drill it myself, will practice first, and build my own tank wide overflow. Having it drilled at the lfs would run around 20 a hole, so I'll just spend the $ on my own bit. Should 2 1" overflows be fine? I am estimating that they should flow about 900gph each.
Im putting together my own filter/sump/refugium; I may try
macro algae, but need to study more first. Are bioballs still recommended?? I have seen a few filters with just lr or no media. I will run a skimmer. What would be the best skimmer for a 90?
I would like to try a
closed loop system, but am not sure if that many holes can be drilled in a glass tank, about 6-8 in the middle and bottom of the back. Anyone with experience in this?
What brand of pumps do you recommend? I was thinking a cl pump @ around 600-1200gph and a return pump @ 1200 or more, Quiet One brand is what I was thinking about.
Any advice will be appreciated
