    My startup tank is coming on sloooowly but surely .... :whistling:
    I'm starting to plan my rock and flowpump placement in the DT.
    The DT size is 120cmx43cmx43cm ....

    I'm aiming for a minimalistic approach, by having 3 smallish "rock islands". To allow better flow around the DT and minimizing "dead-spots"

    First question:
    In the layout below .... will the rocks at the base of the overflow cause a problem around the bottom corners of the flow?

    Or should I rather move the left "island" like this? :

    I've also got 2 x flow pumps ...
    Where in the DT should I place them and wich direction must they point (according to the A,B,C,D,E,F,G,H markings on the sketch?

    Thanx in advance!

    Little islands and little place for fish to hide or sleep.

    Riaan ... the other idea I had, was to make the "islands" higher, with some sort of "cavity" under each of them? ... not sure how difficult that would be to construct though ..

    HI

    I would go with option two, having rocks against a surface always causes issues if you decide you want to clean it (one day).

    Remember to leave enough space between the islands and the glass so that you can get a magnet cleaner in as well.

    Use multiple rocks to build your island, the spaces inbetween provides hiding place for the fish then.

    You can also use rods to build a higher island and/or create space under the rock for more hiding space.

    OK at the moment I've got one flow-pump sitting at B, pointing straight to A ...
    The second one sits almost at A (in front of the overflow), and point down to F ...
    Does that sound OK?

    sounds cool

    Or put them for a test on both the end panes, in the middle slightly up from the centre pointing directly at each other. Check the random flow that creates.

    Flow pump B pointing towards E would create more turbulent flow, or even A and B aiming towards the middle of the front pane. Play around a bit and see what works best.
