Too much flow??

[toadass]

Hi all

I have a 200 litre tank with 2 filters running, total flow is around x15 turnover with a JBL e1500 lph, and Eheim that runs 1000lph.
The Eheim has a reactor running through it with FE as CO2,

My question is does both filters have to be running 24/7? Surely the x10 turnover is for when there is CO2 in the tank...Right???

I was planning on putting the Eheim on a timer to come on just before the CO2, the reason for this is the better half has purchased herself a Betta who isn't too keen on the flow, i was just gonna calm the flow down a bit to help the fish out.

Or is there something completely wrong with running it on a timer?

Many Thanks guys
Toad

I run a separate circulation pump on a timer, it comes on & goes off with the gas.
As long as the pump is not part of the biological requirement then it is fine.

I have a Koralia 4000 plugged into the same timer that controls my lights - gives the fish a rest at night!

The problem i can see assuming that your talking about an external filter, is how are you going to prime it if its on a timer?

You would only need to prime it if you physically disconnect it, surely? With all the pipe work connected none of the water is going to move anywhere.

Tho, how would shutting it off affect the bacteria colony? Surely not having fresh water/O2 rolling over the media would have a negative effect?

As others have stated above having a power head or circulation pump running on a timer is probably an easier solution.
