    Can you help me with a question on flow rates ?

    I am running a marine land 4500 with a Gph of 1275 I am feeding my sump with a double Aqueon overflow, my marine land currently keeps up with the flow from the sump without sucking air
    I am also running a Eheim 2215 canister with broken LR and sand, bio balls in it.
    The tank is a 90 gallon cube, sump is a Aqueon pro flex 3

    36 inches from pump to tank (uphill)

    Do I have sufficient flow rate for an anemone ?

    What is my flow rate , do need to increase or decrease it, I have a fx5 that I was going to use, but that seems a little over the top.

    So you are actually running 750 GPH max out of the 4500 (due to TDH = Total Displacement Height of roughly 4'). The canister filter is about 150 GPM.

    For minimum soft corals like 10-40X turnovers. Nems would need something like at LEAST 50-60 turnovers/hour. Some run over 100 (myself included) in their tanks.

    For your tank - if its a 93 cube you have probably 75-80 or so gallons of water (depending on the ammount of sand and rock).

    Let's go with the smaller number for argument's sake. That is 75 gallons X 50 turnovers = 3750 GPH MINIMUM FLOW. I stress MINIMUM and that is for the lower tank volume value. The turnovers are generally calculated based on the DT volume - the sump is not considered in this calculation since the powerheads do not circulate the sump water.


    With your current setup- you are running about 900 GPH. I would recommend an enormous upgrade in flow before you consider a nem. Also RESEARCH RESEARCH RESEARCH. By asking a basic care question such as flow rates would suggest that you still have some learning to do before you would be supported by this forum in the decision to house a nem.

    Also, have you been testing/maintaining your "Big Three" parameters? Calc? Alk? Mag?
    What kind of lighting do you have? Nems need very strong light and very strong flow. Nem's can also easily nuke a tank in a matter of hours with the toxins they release if they die.

    Many reasons to take great caution when getting into this facet of the hobby.

    Thanks, research and asking questions is something I am most certainly not afraid to do, for sure. Can type all this into a search engine, or ask some "no clue" at thepet store, but when I ask here I get the answer and some advice too.
    I am conducting daily tests, I complete the whole range every single day, my tank is only 4 months old, and while I currently have a 55 gallon tropical , a 350 gallon gold fish tank, and a 1200 gallon marine tank (to get started) this is my 1st shot at marine, so I am going slow and will surely get there, I love my fish and spend most of m non working day taking care if them.
    I might add the fx5 into the tank tonight and then take the enhiem filter away next week, that will definitely get the flow up.

    Lights, is where I am this month, looking at the boost ? As recommended on here, just need to see how. Can install without hanging them, or boiling the fish

    Thank you for your help and advise
