flow rate

    so i have wanted a achillies and or a gold rim tang for quite some time now and i was just wondering what makes them so hard to take care of and are there any secrets or tricks to keeping them alive and healthy thanks -jared

    Hey guys! I had a question. When calculating flow rate for the tank I do the simple equation of powerheads + sump pump/ gallons of water = flow in system... Now.. I was wondering, since I just set up my first sump, do I use the entire water volume of the entire system or do I just use the DT...
  3. The THINK Tank
    I am hearing conflicting opinions on sump flow rate. Some are saying to match to skimmer processing rate and others say up to 5X tank volume. I have also heard that for a Bare Bottom you want 10X or more. Lets examine a skimmer in the sump and the inlet and outlet in the same chamber. The...

    My question is related to flow. To start will be LPS / Softies with a move to SPS. I've recently put up a new 90 that is going to be partial reef to begin and then grow from there. Over the years i've done FOWLR and in my 150 I've had 3 Koralia Evolution 1050's. In my 90 i've put 2 - Jebao...
  5. Substrate Free Tank Husbandry (Bare bottomed)
    I hear all the time that you can never have "too much" flow in your tank. I currently have a 14G Biocube and since I'm going BB, is two hydor koralia nano 425s and a sicce syncra 185 gph return pump enough for my tank? Not enough? Too much? I don't want to go overkill because too much of...
  6. Water movement (pumps & wavemakers)
    I posted this in an other section with only two responses with opposite opinions so I figured this maybe a better place to ask. I have a 3 gallon Picotope that has been running for a few weeks now. Its doing really well and I just added a Hydor Koralia 240 to the tank to increase the flow. I've...

    Hi! I've been stalking your forum for 6 months now!! and after a ton of research I decided to go for a 55 gallon reef tank! please keep in mind that this is the first fish tank I've ever had in my entire life but me and the wife are very excited about this project. I let the tank cycle for a...

    alrighty so after using a head pressure calculator my eheim 1250 will only have an output of 136 gph, but my skimmer will do 92gph. so i will want to scale my pump output back to 92 gph aswell. my emperor uv sterilizer needs only 60gph to kill viruses. here is a crude picture of the design...

    I will be getting a new tank this summer and am looking at a 120+ gal. Reef ready tank most likely w/55gal sump. My question is on the overflows. I need to know if its better to have 1 in each corner or 1 larger one in the center? I'm sure there are advantages to both but I would like to here...
  10. Water movement (pumps & wavemakers)
    The idea is to use one large return pump and divert off of it through my chiller/heater, UV, and Canister filter. I want to turn my 150 gallon tank and sump over at least 4 times, so I am going to want to monitor how many GPH are going to the tank and to this secondary loop. What do you think...

    I am currently trying to decide on a return pump for my new 120 im building. The built in overflow says its rated "up to" 700gph which seems pretty low for a 120. The skimmers pump says it pumps 900gph so I would assume I want to match that? I was thinking of a mag 12 which at 5ft head (which is...

    im thinking of eventually running gac and gfo in separate reactors. what is the optimal flow rate for each? i know the gfo is just when there is surface tumbling, correct? but i havent really been able to find anything solid for the carbon. thanks rob
  13. Water movement (pumps & wavemakers)
    I'm looking to upgrade the flow rate in my biocube 29 to create enough flow through the filter for SPS. For current in the display I have a koralia 425 and a koralia 240, and the protein skimmer is the Aquatic Life 115 mini skimmer. My base question is, will this all process enough gph for SPS...

    I'm just jumping back into the hobby after a 20+year hiatus ..... and I see these terms quite often during my research in regards to lighting and internal flow ..... "LOW, MEDIUM, MODERATE, HIGH specs for corals ..... really??? So .... would love some input here and hopefully some kind of...

    Is a hydor koralia nano 425 gph enough for a 30 gallon reef tank?:confused:
  16. The THINK Tank
    flow rate, drain rate balance was difficult to dial in with my sump being 40 some feet away, and 1st time using new pump Blueline HD 70 39' head with 1" inlets and outlets. I upsized all my plumbing where I could dropping below floor level 2+ feet not quite 3' I don't think. The run is...
  17. General Reef Discussion
    Hmmmm so i recently purchased a 150 reactor and some NPX biopellets from webaquatics.com and have a dilemma. The "kit" they sold comes with a pump a that flows 108gph max. I am running 200ml for a 55 gallon system. TheNPX insert that came in the reactor suggests 350gph for bio pellets. At first...
  18. Nano Reefs
    I have a 14 gallon bio cube that has been doing pretty good but there just isn't enough flow in the thing. The pump is only rated at 137 GPH and that seems very low too me. Does anyone know of any replacement pumps I could use to increase flow rate? I could add a powerhead to the thing but...

    hi all have a couple questions im finalizing my new 72 bow set up the stand is finished ,checked tank for leaks, now gotta drain it ,drill it ,mount overflow box and return lines ,finish my diy sump and then plumb it ...main questions here are pertaining to running an efficient fuge ,as i have...
  20. General Reef Discussion
    should i use a mag drive7, rated at 480gph at 4', or the mag drive 9.5, rated at 800gph at 4 feet and use a valve to dial it back. i was unable to determine if the 9.5 has a flow valve on it. the overflow is rated at 600gph. i plan on using two 1050gph powerheads, so im thinking the decreased...
