Update:
Thinking about doing few changes, let me know what you think
Flow:
-> Two Seio 1100 Power Heads
-> Return flow from Aqua Clear 110 DIY Refugium
-> Aqua Clear 70 Power Filter
Filtration
-> Aqua Clear 70 power filter with sponge, carbon & poly filter
-> 2-3” Shallow sand bed
-> Around 100 lb of Live Rock & Dry Rock
For surace skimming, instead of going with PVC overflow, thinking about going with AquaClear Surface skimmer. Might not look pretty but seems like lots of people are using it with great success and it also works without auto-top off as i will most likely have manual top-offs
