    Hi All

    I have a skimmer question. I currently have a Reeftek TS1 for a 350L tank. The TS1 is only rated for 300L so I should get at least the TS2. My question is what does the bigger skimmer give me? Why bigger? Does skimming wet with my TS1 not so the same thing?

    Thanks
    Paul

    Hi Nudi

    The bigger skimmer will give you increased contact time within the skimmer body and more importantly produce more liters of air per hour, all this adds up to better skimming and the larger skimmers ability to pull out more nasty skimmate.

    Bigger skimmer will take out waste faster...
    Smaller skimmer will take out the same waste but slower...

    Rather take out the baddies faster before it gets a chance to break down into NO3 and PO4.
    This also depends where the skimmer is located in the sump and the power of the return pump if it is an insump skimmer aswell as flow inside the main tank to get the nasties down to the sump...

    Ok I got carried away..lol

    So depending on the nutrient export system, a skimmer can be any size, right....

    Unless you want to over complicate things, your skimmer should be your primary export system.

    There is a reason why the simmer is called the heart of the system!

    Rule of thumb, skimmer 1.5 to 2 times your water volume.

    A skimmer is a wonderful bit of kit. But it is not the heart of any biological system. It will reduce the organics through the filter. However it is the NO3 and PO4 that concerns.

    So a huge skimmer will give better water quality?

    and what would be the opinion on running 2 smaller skimmers instead of 1 bigger one be? as an example would 2 x ts1's be as efficient or more effiecient than 1 x ts2 in the same system?

    Needing a bigger skimmer depends on your Bio Load. If you are finding your skimmer is not keeping up then a well thought out upgrade is a good idea. Try not thinking of it in terms of water volume alone, but what your stocking is and will be.

    I dont think bigger is always better..... If the skimmer is larger and the system is low in nutrients, then there might not be enough organics for the skimmer to maintain a head to skim out gunk in the tank...so the skimmer is no longer operation efficiently.

    Ive got a skimmer way overated for my tank and it is almost useless with a low bio load.

    We can ask....
    Will a skimmer Reduce my nitrate?
    Will a skimmer reduce my phosphate?

    Exactly what will a skimmer do for my/ your tank?

    Yes. I suppose it does the same in most instances. The understanding is mostly a bigger wind will blow the smell away.

    A skimmer will not add extra O2 to your tank as O2/CO2 is exchanged by the ratio of surface to air. For example, the larger the surface area and the larger the agitation of that surface area the more O2/CO2 will be exchanged.
    A skimmer is not the most essential piece of kit in an system, what about heaters, or your light unit, or even a well made tank.
    We have a little tank at the store that has NOT had a skimmer in ages, we do a 50% water change every two weeks. and The inhabitants are fine.
    Granted, there are only three fish in that system. ;)
    So @nudibranch, Paul, you need to ask yourself this question..........
    Do my inhabitants look happy, am I overstocked in terms of fish numbers, what is my overall vision for my tank, SPS, SOFTY, LPS?
    These will definitely make a difference when you are deciding to buy a piece of kit for your tank/ replacing your TS1 skimmer.

    However, keep this in mind, a 2000 litre system with two fish has less of a biological load with a 150 litre system with 8 fish.
    Happy Reefing.

    So from reading the above it sounds like my small skimmer could be the problem for my high nitrate and phosphate problem. I was heavily stock and reduced the load by a third but this made no effect on my parameters. I may still have a big bio load and my skimmer can't handle it.

    Possibly, but before lashing out thousands on a new skimmer, first look at what other methods you employ with regards to nutrient export, things like: do you use bio pellets, algae scrubbers, phosphate removers, carbon, water changes, excessive feeding, old lighting, detritus build up in rocks etc. etc. All these can contribute to an increase in Nitrates and Phosphates. My advice would be to list, in as much detail as possible, what you have in your tank, equipment and livestock wise, including clean up crew, list your maintenance regime, feeding methods etc. That way the guys will be able to probably pick up on other things that may be causing the problem. It's very seldom one thing that is causing it, normally it's a combination of 2 or 3 things that can be easily rectified without spending money on major upgrades. :) Having said that, I think a TS1 is definitely too small for a 350l tank. I personally, having owned one of those skimmers, would rate it ok for maybe a 120 litre nano.

    If your tanks running fine, I'd keep it as is.

    What are your current Nitrate and Phosphate readings?

    Nitrate between 20 and 50, I would say closer to 50 and phosphate 0.18

    Paul, @nudibranch. Nice looking tank. You are doing things correctly. Your CUC will not add any nutrients to your bioload. Fourteen fish doesn't seem excessive either and your feeding regiment is spot on.

    How long have you had the biocubes in? Why the bioballs (they can become detritus traps), from what is shown, you have enough biological filtration? If you want to keep the bioballs, keep them clean.

    A new skimmer would be great, like Dean has said, but let's see what can be done first in terms of your current setup.

    Skimmer underpowered for bioload, nitrate factory in sump mid compartment and insufficient flow through phosguard.
    Feel free to give me a call on 083700seven one double four.
