Is This Set Up Ok For A Fowlr Tank?

    Hi Guys
    I have a spare juwel rio 240 tank and an Aquael 2000 external filter so I am thinking of trying marine. I have kept Discus for 35 years so not new to fishkeeping but an absolute newbie to marines.
    I am going for a fowlr set up, there is no sump and the cabinet will not hold a sump so cannot drill either so a sump is out of the question, I am thinking of using my canister filter, my plan is to fill it with sponges, phosguard, carbon and matrix, its a large filter so can hold quite a bit of stuff, I plan on buying a tunze 9004 skimmer and use live rock.
    The questions I have are, is this set up fine?
    What if anything should I add or leave out of the canister filter?
    Is the skimmer ok for the size of tank?
    Anything I should or shouldn't have that I haven't mentioned?

    I know canister filters are not widely used on marine tanks but that is what I have and what I am going to use, I have seen too many full blown reef tanks run on just canister filters to know that they can and do work so I need as much help as possible with this situation.
    Thanks guys

    Hi John, as you say there are plenty of stunning reef tanks that run on canisters and they do a great job of housing some of the media ( phosguard, carbon) as you intend and also a little extra water capacity,

    Where their use in a reef tank and a freshwater system differs is in a freshwater tank the canister filter is used to harbour ammonia eating bacteria whereas in a reef tank that bacteria live and colonise on the live rock, it’s best to keep the canister and any sponges in it regularly cleaned and free from detritus so there can be no build up of bacteria in it as this can be detrimental to your overall water quality.
    Personally I wouldn’t use the Matrix in it as it’s not needed.
    Doug.

    Hi Doug
    After keeping Discus for 35 years I am well used to maintenance, back in the day I used to do 90% water changes every day, things have changed a bit but im used to keeping absolute pristine water so maintenance wont be a problem.
    Im thinking then that the live rock will be my biological filtration so as you say matrix wont be needed.
    I understand the importance of a skimmer.
    so if I fill my filter with sponges, and carbon and phosgauard that will be enough?

    good to hear you appreciate the importance of a good skimmer
    personally i think they are very underated

    but to really understand what you need for your FOWLR
    do you have any thoughts on how you are going to stock it ?

    filtration in my opinion is often sold wrong i.e. on tank size
    when i think it should be sold on bio mass

    1 x 6" fish produces a lot more waste than 6 x 1" fish

    and Tunze has a great reputation in our wonderful hobby

    Ive seen enough videos to know how much waste a skimmer pulls out so anything to make water pristine is good in my book.
    as far as stocking goes ive got a small list but have to check compatibility.
    flame angel
    harlequin tusk
    magnificent foxface
    valentini puffer
    dwarf lionfish
    snowflake eel
    bi colour goatfish
    wrasse (don't know which ones yet as so many to choose from)
    Obviously I wont be having all of them but that is my list so far.
    I don't want to stock too heavily as its detrimental to the fish in my opinion.

    Im looking at the tunze 9004 dc skimmer rated for 60-300litres but not sure if I should go for 9012 rated for 200-1200 litres. the 9012 seems excessive for a 240 litre tank but the 9004 fits the bill but im not sure its enough for a fowlr tank. Any opinions?

    Personally I would go for the bigger 9012, your possible fish list has a couple of messy eaters and the 9004 would be pretty much at its limit.

    As above really
    Potentially a few big fish on that list
    Bigger normally better
    And if you ever decide to go for a bigger tank in the future you will still be able to use it

    here is my list of stuff im thinking of going to get, again let me know if im missing anything or things to add or leave out.
    live rock (how much for a 240 litre tank?)
    sand
    already have heaters and canister filter.
    tunze 9012 skimmer
    phosguard
    fluval carbon ( still got loads for my discus tank so going to use that unless there is a better brand for saltwater?)
    red sea reef mature pro to cycle tank with.
    red sea ph/alk test kit (already got ammonia, nitrite and nitrate test kits)
    red sea foundation B powder to keep alk stable (don't know how important it is in a fowlr tank)
    instant ocean salt
    refractometer
    powerheads ( need to look at. Any recommendations?)

    That's all I can think of so far.

    I think the rule of thumb is 1kg per every 7 litres of water
    Wouldn’t worry too much about maintaining alk for fish only
    Reliable thermometer unless you already have one
    Lighting don’t need too much but would still have something reliable
    Power heads. Depends on budget really

    ive got all the basic stuff like lights, heaters, thermometers etc.
    Regarding powerheads budget not imperative but don't want stupidly expensive ones like vortech and don't want cheap noisy only last a week ones either.

    They look good but I do I need the million different settings? If not then its not worth expense.

    Just had a quick look at auto top up and the ones ive seen are for sumps so does this mean I have to top up manually?

    Pretty sure @reefloat do a sensor that can be placed in the tank.
