    Hey all,

    So, i've been keeping my little 2ft low tech nano going with a rubbish little 300l/hr internal canister filter. I put filter floss in which i change every three days or less! Today I wanted to buy a sunsun JVP 101 - just under R100 (good price?) but I saw that it was 5000L/hr (i'm sure this is overrated, as usual). It has a ceramic shaft (well, its not metal at least...)

    Question is... even at 300L/hr, the flow isnt terrible in my tank. Surely 5000L/hr will turn my tank into a wirl pool? :p Or would this be a good idea for the tank?

    As for what corals I have... NO SPS, two small LPS - a frogspawn and a little purple trumpet. Softies are mostly zoas, one blue speckled finger leather, lots of xenia, polyps etc.

    The 101 pump is rated at 3000Lph, the 102 is 5000Lph. Believe me sunsun pumps are definitely not overrated. I put a 3000Lph in my 128L Tl-550 and it blew everything around and blew the sand around like crazy.

    Damn! Your boyu is almost double the volume of my tank! So what do us nano owners do! how do I supply the right amount of flow for a little 70L tank! Sigh. I am thinking of doing a DIY magnetic driven pump, but I'll never have enough time off from my academics for the build :-(

    Just try it. It works on my 3ft tanks as long as you don't have a very fine substrate.

    My tank is a 2ft! And I have beach sand as a substrate :-( My tank is also all softies and LPS, not SPS like yours... So probably overkill on the flow?

    Maybe I'll try it and then use it as an excuse for a bigger tank... :D

    Lol, 2x fwater and 1 mantis tank. Don't knock the bathwater too hard. It is a beautiful south america biotype - and i havent TOUCHED the tank in two months, just a jug of water to top up evaporation and daily feeding. Maintenance free tanks are pretty awesome :) No doubt that the marine is so far ahead my favourite. My mantis tank is also great, havent done a water change in ages and its only 20L. Packed with caulerpa which seems to suck up the bad stuff...

    Compared to my nano, my planted tank is a breeze :)

    Why don't look at the small Seio props? You get a Prop 320, I think it is 1200lph - and the Prop 530 is 2000lph.

    I think if you place the prop correclt it will work lovely, aim it blowing at the front panel or the back panel and not directly into the open space into the tank and see what happens, the current in the 'real' sea can be immense somtimes so i advise experimenting, whats the worse thing that could happen?? :p

    What works for me with pumps a bit to big is to put it low down in the tank and aim it up towards the surface

    Thanks for the input, I'd like to try one of the lower flow rates... 3000L/hr is huge. I have the 300L/hr aimed at the front glass already! So can only imagine what 10x the flow would do!

    Any way to power down a pump? Like a dimmer for a light switch? that would be very handy... I know some of the vortechs can do it

    Update: Dimmer switch control on a pump not possible. Pumps are inductive... Only simple techniques to restrict flow... not so keen on that

    Aha! What about tearing apart an old fan and using the speed control on the pump instead!?? any electronic buffs?

    I think buying a bigger tank is the best option.

    who did you steal those from?

    youve seen my room havent you? Just get rid of the laptop and work rubbish and your desk is more than big enough for a large cube. I need to find a new home for that neon damsel so now you have two resons to upgrade.
