Flow and powergead position questions

[bdejong1112o]

Lets get the details outlined first.

I have a 220g, 72" x 24" x 30" tank.
Aquascape is shown in the picture below.
I have the following livestock in it.

• 4 Pajama Cardinals
• Pair(Male and Female) clown fish.
• Fire shrimp and coral banded shrimp
• 4 small zoa frags on the right side of the tank
• A GSP frag on an island on the left side
• I have a hammer, rodactus, a trumpet and teo blasto frage sitting on the sandbed right now as theynare new to the tank

I am a softie and LPS focused person now as I want to be sure that I can keep up with the needs of the inhabitants.

So I am looking at and trying to understand flow and what is to much for what I have in the tank and will continue to add to the tank. I have teo MP40 power heads, new version and a gyre 250. The MP40s are on the sides and the gyre is mounted horizontal on the back wall.

The MP40 program is somple and runs in lagoon mode most of the day at 25% with a 45 minute nutrient run starting at 10:30pm to stir things up for 45 minutes and then tidal at 25% for the rest of the night as shown in the below screenshot.

The gyre runs a pulse, 2sec,2sec, 20% to 35% all day long.

I use the GSP as kind of a visual indicator of movement and it looks like there is plenty of flow in the tank since it has a good amount of movement. Xnat figure out what video format R2R wants. Wont take a MP4 or AVI. Once i figure that out i will post a quick video of the GSP movement.

But, how do you really know how much is to much? I see lots of general terms like low, medium, high but what or how can that be measured. To me if I set the MP40 to much above 50% it looks like it will blow everything away, lol.

You really have to use your eye honestly when placing the corals.

I set my flow and animals to the highest flow spots and see how they respond. A lot of corals esp softies will take a lot more flow than is usually thought.

That and the high med and low is kinda odd way of liking at it.
It. 100 is high so 10 is low. What If 1000 is your high? Lol.

When I set my flow in the empty tank I just looke for good overall flow (use food or dust ) with as few dead spots as possible. Then put in coral.
You'll have high spots med spots etc. that's good, you'll buy high med low flow corals.
