Thank you very much SM. Now should that be 96 watts per side or total. I will do a 2 sided.

Thank you very much SM. Now should that be 96 watts per side or total. I will do a 2 sided.

96 total watts is both sides totalled up.

Thank you for elaborating and for your dedication.

+1.

I'll post a pic soon of my new setup

and some q's I have

You are welcome. It's fun to see everyone's tanks getting better.

No opinion really. Mine never really drops.

I was asking more specifically higher mag affecting algae growth on the ats-

Not that I know of. Higher alk can help though.

If the slot is 1/8 then the flow should fill in as the growth occurs.

IMHO ATS > refugium

You can have a fuge, just don't put macros in it. Use rock rubble.

How much will you be feeding?

Scrubbers are now sized according to feeding. Nutrients "in" (feeding) must equal nutrients "out" (scrubber growth), no matter how many gallons you have. So...

An example VERTICAL waterfall screen size is 3 X 4 inches = 12 square inches of screen (7.5 X 10 cm = 75 sq cm) with a total of 12 real watts (not equivalent) of fluorescent light for 18 hours a day. If all 12 watts are on one side, it is a 1-sided screen. If 6 watts are on each side, it is a 2-sided screen, but the total is still 12 watts for 18 hours a day. This screen size and wattage should be able to handle the following amounts of daily feeding:

1 frozen cube per day (2-sided screen), or

1/2 frozen cube per day (1-sided screen), or

10 pinches of flake food per day (2-sided screen), or

5 pinches of flake food per day (1-sided screen), or

10 square inches (60 sq cm) of nori per day (2-sided screen), or

5 square inches (30 sq cm) of nori per day (1-sided screen), or

0.1 dry ounce (2.8 grams) of pellet food per day (2-sided screen), or

0.05 dry ounce (1.4 grams) of pellet food per day (1-sided screen)

High-wattage technique: Double the wattage, and cut the hours in half (to 9 per day). This will get brown screens to grow green much faster. Thus the example above would be 12 watts on each side, for a total of 24 watts, but for only 9 hours per day. If growth starts to turn YELLOW, then increase the flow, or add iron, or reduce the number of hours. And since the bulbs are operating for 9 hours instead of 18, they will last 6 months instead of 3 months.

Does not matter where it goes, as long as it gets proper flow and lighting.
