    Hi guys

    I have a Reef Octopus BR110 pellet reactor, and the pump is a Hailea 6520 1000LPH. The pellets are barely moving. I havent soaked them for24hrs yet, just did a test in a bucket to see if the pump is strong enough.

    Will that pump do the job or will I need a bigger one? My water volume is arounf 700L

    Maybe go with a slightly stronger pump, they need to tumble "softly" over each other... You should look at the next Hailea pump up in the range. Get it and try tone the flow rate down to get them tumbling. I'm no expert, I have only had my pellets for 1 1/2 weeks but that is what i'd do.

    Hey I see you are selling the reactor... Not going with pellets anymore?

    Hi Rakabos,

    I am running the same reactor on a tank with a total volume of around 700l, i am using the hailea hx6530 and the pellets are tumbling nicely, i added a control valve just in case its to much and it seems that the 6530 gives jsut enough flow for 500mls of pellets.

    I use a 1000l pump on my BR70 reactor and it works perfectly, your pump might be too small. Have you checked the mesh trap inside the top of the reactor yet for clogging, as soon as my pellets stop tumbling its 99% of the time due to the mesh trap being clogged.

    Thx guys will try a bigger pump. No mesh at the top so that aint it.

    Let me know if you would like me to upload a video of the pellets tumbling on a hx6530 pump:)

    Hi rakabos

    Your problem is flow... The br 110 can take 800 ml pellets and in my experience you need 2000lph pump to have it work properly. Also try and get an adjustable pump or you wil have to get a tap to control the flow with lower quantities of pellets. Give me a shout of you have any questions!

    Hmmm, maybe while you are doing all your experiments, you can find a general optimum ratio of flow to volume of pellets in a fixed cylinder diameter...?

    Agree with willie here, like my reactor is running, got an over rated pump and a ball valve to control the flow, tumbles like a boss!

    Hmmm I think that is a good idea!!! Only issue is the variable of Mulm. The more Mulm you have the more flow needed!

    @NickW

    Please sir, upload that video on 6530 full blast, so i can get an idea before spending the $$$

    Also, do you guys use the stock plumbing that came with this reactor?

    Nick.... Just a quick thing here. The way you are restricting the flow here is not the right way as far as I am concerned. You are closing the main line and therefor putting strain on the pump. It would be better to have a T-piece on the uplift pipe, low down and then have a pipe going back to the sump. You need to add the ball valve on this pipe. This way your pump pumps at its full capacity without any back pressure and you still have control over the flow.

    Was also wondering about just valving a pump, cant be good for a pump if it is restricted without a t-piece. Probably also adds to noise levels

    Understand what you guys are saying, i do agree :) however with using the 5340 pump the valve is still fully open and the pellets are tumbling nicely, so in essence the ball valve there is a waste as it is fully open any way and therefore not restricting flow, if i had chosen a bigger pump and would need to constrict the flow, i would go ahead with the T piece as Marius suggested.

    I could still add the T-piece if you guys advise it? but i just dont see the point as there is no need to restrict flow and therefore no need to use the ball valve at this moment in time, but i suppose the T-piece could come in handy at a later stage??
    :)

    Nah no t-piece needed if the valve is fully open

    @rakabos here is the vid requested, this is full blast and the way i am running my pellets now, is it too fast? (it looks faster in the vid due to the motion delay and blur) ( @mariusmeyer )



    Sorry for the bad quality vid.

    That seems a bit too fast, try tweaking down a bit so that it's fast at the bottom and a nice tumble the rest of the way up....

    something like this:
