Regarding Powerheads

[dayzofspeed]

quite a simple question really, i know i need to be looking at a minimum of 20x turnover and i have a 240l tank, now obviously with rock added and sand soon to be added i'm not going to have 240l of water but should i still make calculations on the original volume or just guess whats actually in there. if my maths is correct i'm looking at 4800 lph so say i round that up am i better getting 1 powerhead that pushes out say 5000 lph or 2 that push out 2500 lph each or do i round up even more and go for 6000 lph or will that create too much turbulence. i will initially be going with zoas and other soft corals due to lighting drawbacks that i have at the moment...... thanks in advance, kevin

2 are better than one. Flow really depends on corals. With those soft corals either would be fine.

Ie rounding up to 6000 or going with 5000..

The more flow the better filtration.

They say that coral needs to have over 36x t/o but don't know how true this is as some coral dont like a lot of flow!

As your rightly say, it depends on the coral, so no, its not true, some want more, others less
