    i'm going to upgrade my tank from a 2 to 3 feet
    currently using RENA XP FILSTAR 1 which i think is too weak for my new tank

    RENA XP 1
    Filter Type - Under Tank Canister
    GPH - 165
    Manufacturer Max Tank Size: 40 Gallons

    RENA XP 2
    Filter Type - Under Tank Canister
    GPH - 230
    Manufacturer Max Tank Size: 60 Gallons

    RENA XP 3
    Filter Type - Under Tank Canister
    GPH - 300
    Manufacturer Max Tank Size: 130 Gallons

    new tank is 48 gallons = 180 litres..... BUT this is my connection...input to reactor to filter to UV to chiller and run for 2m long hose before output... so shall i get XP 2 or XP 3

    Why don't keep using this xp1 and get another filter or xp1 if you like, 2 is better than 1 in the long run just in case one fail.

    Get the XP3 and connect the UV and chiller to this one. Connect the reactor to the XP1.

    XP3 also if you want to use one filter. The chiller and long plumbing will cut the flowrate quite significantly. You can always adjust the flowrate down with a valve at the outlet valve of the filter... but you cannot ever increase flowrate. Also, if you ever upgrade to a bigger tank, you don't need to buy another filter.

    Anyway, it's better to connect the extra equipment after the filter. You don't want the equipment to get clogged. I noticed you placed the reactor before the filter. The UV filter should be the first after the filter. You want the cleanest possible water going into the equipment.

    reconnection of pipings

    just a question... input pipings to filter a bit longer doesn't affect anything right??? BUT output pipings longer would mean affect flow rate right... need to confirm this before i do my reconnection to my rena XP 3...cause i'm going to swop position of my input and output places.. in order to shortern my output pipings
    Confirmation of reconnection...
    INPUT - UV FILTER - FILTER - EXTERNAL REACTOR - CHILLER - OUTPUT(rainbar)
    thanks for advicing...

    Length of piping used will affect flowrate whether in input or output terms, but that effect is minimal in my opinion. Instead, the large flow-rate reducers will be all the equipment you're putting the water through.

    Psst, not saying you have too much equipment though, just make sure the filter is powerful enough

    Filter Type - Under Tank Canister
    GPH - 300
    Manufacturer Max Tank Size: 130 Gallons

    my new tank size is 48 gallons.. i think my filter is strong enough right... bought XP 3 so can connect more stuff... heehee anyway...squee..i've seen your reactor... thought of DIYING one exactly like yours... but instead of using PVC pipe.. thought of using lock and lock those transparant tupperwares.... then i can see the bio balls swirl...

    Just in case you misunderstood my posting... I suggested that everything should be after the filter. That means tank->filter->UV->(other stuff)->tank.

    One more thing... you may want to keep track of this thread http://www.aquaticquotient.com/forum...ad.php?t=12672.
