    hi

    i had this sump made by idol marine but i never know what i wanted then and now i need to change it. as you can see in the pics below the dividers are very low and bcoz of that when the water level drops, it drops in all the compartments and that causes the skimmers water level to go upside down aswell. the second chamber where the sand bed is, is to small for a dsb so il have to go the np pallets route. what would you guys suggest i do. the sumps dimensions are: 98cm long 35cm high 37cm width
    the current divisions are: 1st comp 43cm 2nd 30cm 3rd 15cm
    i was thinking of doing lr in the middle chamber

    Replace the glass on the left with whatever height you want, I reckon double that, the water level will be that height and remain constant in the left chamber. LR and chaeto a good bet, you can raise the glass on the right a bit so you can fit more LR in.

    thanks

    are np pallet reactors insump or ext?

    can cheato go on or above lr?

    one more thing my atu swith is circled in the pic below if i raise it would it effect the salinity? its placed just above the return pump and sometimes the atu does not work so for safety sake[​IMG]

    I think they're external but never used one. Maybe pack the LR to the right, with the chaeto on the left getting good flow from the first chamber. When you raise the ATU, top up the sump with salt water. Best you get that ATU fixed though, you dont want it dumping in huge amounts of RO

    Pellets run in a fluidised bed filter, hang on(seperate pump), internal(including pump) or external with pump feeding from the sump can be used, all depends on the space you have to fit.
    I would advise hangon fitted close to your protein skimmer, the outlet from the N/P water must feed your skimmer directly as close to the skimmer inlet pump suction.
    Also, your heater must be submerged completely. Also the power plug must be above the water level....yoiu dont wanna shock when there is a flood.

    Is there members in your area that can pop in for a coffee and some advise?

    turn the skimmer 90 degrees. First chamber can be a lot smaller. Reckon that will increase the DSB area by 50%

    Live sand provides more surface area than live rock. Rather keep the DSB.

    No need for baffle. First divider should be 10mm taller than second. First pane just under the skimmer outlet. Water level above return pump max 30mm lower than last divider. To prevent a waterfall effect pulling bubbles down.

    Riann am I correct in saying that if I make my 1st divider 15cm high then the second should be 12 or 13cm high?

    Gaboon the atu doesn't over pump ro it doesn't do a top up unless I suck/pull don't know why this happens its almost like the water gets stuck by the motor and then stops and needs a kick to come through

    no, make first higher. High as possible. To just under the horizontal outlet part of the skimmer. (The T and elbow pieces.)

    Second divider should be 10mm lower than first

    iv managed to change the sump, thanks to a friend of mine who did it for me. the pics below will show the change. the new divisions are:
    1st comp: 33cm 1st divider is 29cm high
    2nd comp: 40cm 2nd divider 28cm high
    3rd comp: 16cm

    in the 1st division i plan to keep the skimmer
    in the second dsb and cheato
    in the 3rd return

    *****the big question is where do i put the atu thingy which controls when the atu pump should kick in the 3rd chamber. the last pic is the return pump pic how high should i stick it?*****

    that looks better

    what make ATU do you have? I prefer the level in the return chamber to be 30 to 40mm below the DSB section. To prevent the waterfall effect from pulling down bubbles.

    i got it from idol tho it doesnt work for some reason, it picks the water from the atu storage but it gets stuck in the motor it doesnt come thru the pipe on the other side of the motor

    so approx where the red line is in the pic below i should stick the swith?
    if its so high would it effect the salinity?
