Would increasing return pump flow reduce nutrients

[Jasongtr]

I have just done a water test on my fish only tank, nutrient levels are

Nitrate 35.6
Phosphate .36

My dc return pump is on setting 10 of 20, i set it fairly low as i didnt want to burn through filter rolls really quickly but its looking like theyll last at least 3 months from what im seeing, so my brain tells me if i up the tank turnover ill pull more out therefore reducing nutrients.

I assume this is a sound idea??

Unfortunately increasing flow won't make much of a difference, if at all. At this point, I would increase your frequency and amounts of water changes.

Not a problem, i dont want to increase flow unnecessarily

Thanks

Possibly. If one of your main issues contributing to your high nutrients are uneaten foods or other nutrient rich particulates accumulating in the tank it could help.
The water carries the detritus down the overflow. More power will increase the amount of water going through the roll…so yeah, if your situation is in line with the above it could help.
You can also lower the roller as that will decrease the pressure inside the unit making it pull the fleece faster which means that stuff has less time to decay whilst stuck on the fleece.

Ok thanks, increasing flow is easy, changing the fleece roller height involves new hard plumbing so thats very much a last resort, the stated nitrate level is the first one using a hanna checker, so whilst i think theres a slight upwards trend in nitrate ill wait a few weeks to see how it goes, its not desperately high i guess, also my 10% weekly water changes are very soon going to be about 16% as im building a reefloat type water changer in the next fortnight

Possibly. Those numbers aren't really an issue for a fish only tank though, are they causing you problems?

Wouldn't say causing me problems but ive got algae developing so thought lower nutrients would lessen this

Imo, no benefit to increasing pump speed to filter thru sox or other quicker.
The bad stuff gets removed in an hour vs 2 hours, does that matter?

Yes that makes sense, thanks
