    So I added a oxygen pump into the sump, bought a really nice silent pump. One thing I noticed two hours of the oxygen pump being in the sump I noticed:

    1. The corals where "out" extended more than they ever been
    2. Had a sulking GSP for three days and the bugger came out in full force


    So my questions really are:

    1. By adding the oxygen am I going to increase the algae growth?
    2. Could the oxygen have helped the corals come out or is it just a coincidence since I did a 30% water change two days ago

    Thanks for the advice.

    What oxygen pump is it and what oxygen are you using?

    i have always added a pump to the sump after adding new fish specifically im not sure why..

    there is a definate difference to adding one even though you would think the skimmer was handling the oxygen factor..

    using one helped me to get rid of cyano at a stage in one of my older tanks...

    still not sure if it was also just coincedence..

    The "oxygen" pump is a normal air pump
    By adding air to the sump u increase the redox potential of the water, oom @Hennie gave me this advice a while back if i remember correctly

    Most definatly could be the waterchange , but oxygen is used up by not only the fish and coral , but allot by the bacteria in the filter , so by adding the o2 supply the dt is getting a higher o2 into there system and doing better .( but the protien skimmer should be doing this as well - just depends if its before or after the biologicle filtration. )

    But the great thing about the air bubbles is the fact that carbon dioxide produced by the denitrifacation process is being removed - carbon dioxid clings to the bubbles and are expelled.

    Either way glad to hear thing are looking better -
    keep up the water changes ;)

    I thought for a moment you pump in pure oxygen from a bottle :p

    One of the reasons I added it was
    1. @dallasg suggested it was a good idea
    2. I have another thread running about diatoms vs cyano and even after the water change adding a phosphate sock (getting the phos reactor soon) I really didn't want anymore cyano :) most the threads I read not only here but all sorts of forums stated that since cyano thrives with CO2 and adding a air pump helped, I went and added one everything I read about it plus the advise was positive

    Yes the skimmer is suppose to do this but I can't see why additional oxygen in the water could be a bad thing :)

    Thank you I def noticed the tank loves it's water changes ;) not sure if the water change process and cleaning the substrate stresses the fish and coral but they seem to enjoy it after the water change.

    I have in the sump:

    1. Floss, bio balls, LR, carbon sock (till I get the carbon reactor), phosphate sock (getting the reactor this week)) then a compartment skimmer and heaters with some artificial LR from dynamax (look like cylindrical chalk sticks with loads of pours holes) after that I have more LR and the return pump compartment. The air pump is in the return's compartment behind the return. Had it in front of the return but it flooded the tank with little bubbles ;)

    Is the air pump in the right place?

    Just so I'm not confused. We're not talking Oxygen pump, we're talking Air pump?

    Where Air = Nitrogen (78%) and Oxygen (21%)

    Ok, i thought airpumps in a marine tank (especially reef) was a no-no..

    except for OZONE on your skimmer.

    Why add a airpump then? A bit confused here now.

    Not really the o2 pump that's a no no its the airstone in the middle of a display tank. Sometimes skimmers don't supply enough oxygen. I'm also running one mainly coz I've got a crap skimmer and it doesn't really do anything. Bubbles in a display tank looks silly.also why we don't really use a pump in a saltwater setup is because the tiny bubbles the airstone created causes a lot of salt creep and salt ends up inbetween everything and everywhere.but that can be fixed by placing an airstone under some filter floss in your sump.that way it doesn't spray everywhere if you know what I mean. An airpump would also affect your ph slightly.

    So if you have a skimmer adding loads of air, dont worry about this, but if you dont, add a airpump with airstone under some filterfloss or the air tubing only.

    What about the air that gets mixed in when your water falls from the overflow to the sump?.. Not asking this to sound dumb, trying to get a idea now of why something like this would be needed..

    And the ph, does the air take it up or down ?

    its biggest affect is raising the REDOX of the water, its the same as adding hydrogen peroxide to the water
    the ability for water to reduce the ion, eg breakdown, the nutrients etc

    ozone is normally used, O3, as its more reactive etc, thats my understanding
