    just get a fairly strong return pump (obviously not adding any piping). that will mix your FSW properly.

    2 x 300 W Heaters (i use the cheap ones as they dont run all the time) 2500 L external pump , plumbed to "suck water from the bottom "outlet" and return from the top.

    If you split the return valva off via a manifold setup you can use it to do your WC as well

    I dont have a huge system. but i mix 125l at a time.
    In the drum i have:
    1 Heater (Set to 25deg)
    1 Sun Sun 202
    1 Boyu 3500l internal/external uplift
    1 air pump.

    What i do:
    Day 1
    Morning, fill drum with RO.
    Heater, Sun Sun and Airpump switched on.

    Afternoon, after work
    Check if indicator light of heater is off
    If it is then water is heated up.
    Add 1kg of Salt per 25l.
    Switch on Uplift (submersed) for extra mixing strength.

    Evening, 3to4 hours later
    Check SG, adjust if required.
    Switch off uplift.

    Day 2
    Afternoon, After Work
    Check SG, always 1.023

    Clean front pane then a little syphon.

    Do Waterchange Before Supper, by supper time everything is settled.

    the aplication is actualy mixing fertiliser for a fertigation system but its stil a salt of sorts and fairly corosive so I thaught stuff desighned for salt water would be perfect I would have thaught a high flow pump like one of the cheap sun sun prop pumps would have been prefered but it seems like most are using return pump type pumps what is the reason for this as there isnt any head to lift or is the smaler higher presure jet the reason?
