That's stunning variety of fish mrlee. Have you noticed any differences in coral growth with the new duo of mp40's? How do you like them?
You said you do a monthly water change. How many gallons per change do you do?
The Mp40es are a little loud, and not as strong as i would like...but the foot print of the pump is great.
I do a 55g water change once a month.
its not a must have item, The only thing good about the mp40 is its foot print...depending on size of tank one would would work, but two would be best. Even with 2X mp40 in my tank don't seem enough flow in a 120g, but with 2X mp40 in a 75 would be perfect i think.
Hmmmm....... The Mp40 max flow rated about 3400gph. You have 2 of them, so total should be around 6800gph. With your 120g tank, it is over 50 times turn over. They should be more than enough for you, unless you didn't turn them on maximum power. With your 120g tank, it's very hard to turn them on at max power 'cause they will cause a big sand storm in your tank I think. If you have 2 Mp40w, it will make a big different 'cause one on and another one will off. They won't cause the chaotics flows in your tank as the Mp40.
As you said, I like the footprint and wider flows on the Vortech. But I dislike the noises of them. They are very loud when it turn on at around 3/4 its power.
Do you have a few vortechs? Would you not buy them because of the noise? My skimmer is semi loud at the moment.
