    Hey guys.

    So i receantly bought two frag tanks from a fellow reefer, and now im stumped!

    Its 2 120x40x29 tanks, both drilled on a stand.

    Now first off , what filtration would you guys advise i use?
    Was thinking of going bare bottom on both tanks. Maybe use the one tank as a sump ie all LR and skimmer. Maybe some carbon. Or use a differnt tank as a sump for both frag tanks.

    Then use the the top tank for fragging/grow out/holding tank.

    Would it be a good idea to keep some fish in there eg so chromises or damsels for the biological side? And if yes, what fish as both tanks are going to be open top.So no jumpers please:lol:

    Then lighting wise i was thinking of just T5's.

    I intend to start with just softies and lps. And later on move over to sps.

    And i will be setting up my other new setup in the next 3 months, and thought that i can use the frag tanks as a holding tank for the corals destind for the new setup.

    Your thoughts and input please.

    Start off simple and upgrade the system later as you do more demanding corals. You dont need a skimmer etc for the beginning as the softies like higher nutrient water. Just some liverock will be fine for filtration. The overflow should give enough oxygen. If you dont have fish in there then you will have to feed your tank some other type of food. Cause otherwise you will not have any nutrients for the corals to use. T5s are perfect. 2 decent tubes like Giesemann actinic+ per tank is enough spread for softies and LPS. You can add more when going SPS or just lift the frags to under the tubes.

    I would go bare bottom. Easier to scrape off algae and crap that settles.

    the stand, is there space under the bottom tank for a sump tank?
    If yes, what is the vertical space you have open? Hopefully enough to fit a TS2 skimmer.

    I will start off putting frags in one tank only, Later as you might need more space I would only then put lights over the second tank.

    Also in the depth, its only 29cm so your water level would be around 25cm. I would go bare bottom. Would want descend enough flow around the frags to ensure detritus and other crap stay in suspension until it reach the sump. With sand in the tank, you would just blow it away.

    Smaller fish like chromis should be ok, but all fish jump. But as you would work more frequently on the frag tank, I would take fish only that do not stress out that much.
    Lawnmover Blennie for algae control.

    There isn't space for a sump with this stand. So either have the sump next to the stacked tanks or just build a new stand.

    Was also thinking of keeping it bare bottom. Would hermits not be a better option than a fish in such a setup? And will i need to run carbon 24/7 with such a setup? And remember im not planing to do full on fragging in the begining, well not yet.

    So skimmer phos remover and carbon ? Will this be enough?

    As I know the setup....this is what worked for me


    • Bare bottom
    • Top tank overflows into bottom
    • External Skimmer feeds from bottom tank to top
    • phosguard

    i would say if this is only a frag tank leave the fish out no need for nutrients in the system, no fish = no skimmer just grow cheato for export

    And where does the coral get its nutrients from? Without food corals wont survive.

    i have also started a frag tank, and have quite a few frags available. I haven't used a protein skimmer and all seems fine... SO FAR. it has been running for a bout 1 month and has live rock in it. As for food, i drop a bit of powdered fish food into the tank, 1nc a week. Only lighting i have is a 150W MH... so any advice guys?

    Much appreciated
