How much flow for reef?

[bk_market]

45gal tank. 60lbs or rock and 2inches SB. How much flow do i need for my reef tank? will house alot of soft and sps, zoas and such.

what is the turnover rate for this?

I bought 2x used Rio900but not sure how much gph they putting out (tried google this but no luck)

What else should i add? Thanx

I would go upward of 20 times the tank volume per hour. With that much rock you will have more of a tendancy toward detritus buildup. So, the higher the better IMO

There is no rio 900. do you mean maxi jet 900.

 

if its a rio, you can find the flow output here.

Are you using a sump with a return pump or just the 2 powerheads?

 

If a sump, what return pump are you using?

 

If no sump i think you need more flow, where are your powerheads placed? sides or back of tank?

lol sorry i just double check it rio90 => 85gph so 2x is 170gph not enough :(

 

 

 

assuming im taking out the 2 rio. my tank is 45gal so 20x turnover is 900gph. Now should I purchase 1x Koralia 3 that give 850gph and place it on one side of the tank or should i get 3x maxi jet which will give ~900gph but placing them different place on both sides?

 

I will probably use the 2x rio for individual coral need

I would go with the maxijets. They are cheap and reliable, also if you add a wavemaker later they tend to not jam on startup. The koralia i have no experience with.

 

I guess you don't have a sump.

The koralia are nice pumps. Thye give a nice broad stream and they are cheap. I have had 2 of the #4 for a few months and i like them

For your size tank, I would go with the maxijets. They are very reliable. I would use these on the maxijet 1200s:

The FLOs do lower the output of the maxijets, but if you had 3 of them in the tank you'd get the results I believe you are looking for.
