    Hi Guys,

    I am busy getting stuff for my new tank that I will be busy putting together soon. So i purchased a H&S 200 2xf2001 skimmer rated for 2000L. My new tank will be around 900L with the sump. What I want to find out is if I could use this skimmer on my current setup which is just around 300L total volume. This skimmer is rated close to 10x more the volume of my current tank. What would be the effects of "over skimming"? I know a lot of guys say there is no such thing as skimming too much, but I am a bit concerned with the huge difference with this skimmer. So please share your advice on this.

    Thanks:thumbup:

    Wet skimming can lower your sg so in a way yes...

    I don't think there will be any issues. just don't skim too wet like MistaOrange suggested

    this is what i read on another forum. So after reading this i decided to post here and get you're guys take on this. Some other forums also say it is bad. So i'm not sure. I can skim dry, as this skimmer will pull out a lot of junk from the tank, so skimming dry isnt a problem. Heres the post from the other forum.

    Wet skimming is when your skimmer cup is full of very dirty water which can be poured out. Usually bubble level in the skimmer neck is set high

    Dry skimming when your bubble level is very low in the neck and you get more like a mud collecting on your skimmer cup

    Well thats how understand it

    Skimmer can be too big. You might have just not enough filth in your system to maintain the foam head in the skimmer neck. Basically the dirty foam will collect, but will not be pushed up and over into the cup.

    Unless you deliberately run the skimmer to skim wet. But that would lead to salinity dropping over time. So you need to check it at least every week.

    Wet skimming is when a lot of water collects in the cup, and the water is light brown. Some times a slight light green tint. Dry skimming is when you get a thick past on the skimmer neck, not a lot of water in the skimmer and it is a dark brown. And smelly

    That's my concern @RiaanP. What about if I dont run this skimmer 24/7 and maybe just 3 times a week? will this be okay or will it be too unstable?

    Do you have another skimmer for the 300L tank?

    If for intermediate setup, busy moving over to bigger tank. A month or 2, it would be OK. As you will hopefully remember to check the salinity. Long term, and as all humans are inherently lazy, you will forget to check it every week.

    Some skimmer impellers cannot be switched on and off. They strip themselves. Just check that before you put a skimmer on a timer. Like Reeftek.

    I am using a ts1 on the current tank. My ts2 pump is stuffed. decided to invest in a good skimmer for the new tank instead of changing the pump I just think its not doing a very good job at this moment. B ut i would rather stick with it and just up the maintenence instead of messing up the new skimmer by switching on and off.

    This is funny but true in a way:lol:

    If you dry skim with that bad boy then I dont see an issue but it would depend on what type of nutrients you require in your water. Try it. What do you have to lose. You will soon see if it works or not

    I used it on my 400L system and it skimmed exceptionally well! I don't see any reason why it wouldn't work on a 300L. I would rather have the reserve capacity of a large/oversize skimmer in case something goes wrong in the tank, like a nennie getting chowed by a powerhead etc... this same skimmer saved me recently when my son decided to feed "Wemo" with a whole tub of Omega one pellets while I was away on business. My wife called and said "babe there is a smell coming from the tank" it was the skimmer cup FULL of reddish brown gunk that it had skimmed out over the course of a few hours! When I got home the next day the tank was fine except for a few fat lazy fish LOL.

    ok, it does depend on the bioload. Enough fish and food, and you could have form enough foam to rise to the top.
    let King_Triton try it and we see. Is it for the tank with the spiny creatures? The leaf fish and other predators. There is not a lot of fish in that tank.

    Hey guys,

    Yes it is for the tank with the spiny creatures. lol.

    At the moment, theres 3 blue green chromis, a magnificent nem, 2 percs, Hawkfish, Leaf fish, and waspfish. Then I have the softies and LPS and one or two SPS. Will try it, just having a slight issue with the one impeller. @Drewton did change it, but not sure why its acting up. He is going to try and find the old ones and post them to me.

    Will let you guys know what happens when I put it on that tank.
