Alot of Turnover rate and flow...

[pepito113]

Hello Everyone... I have a 65 gallon tank with a return pump at 800gph, 2- Koralia number 3 flow at 850, and a Koralia number 1 flow at 400gph.. SO 800+850+850+400 gives you =2900gph...
2900/65= 44x turnover rate...
But I still get waste and nasty stuff building up on my rocks... Every 2-4 weeks I get a trukey baster and blow all the waste of the rocks hoping it will stay suspended for my filter and skimmer to get it... Should I had another powerhead??? I dont really have any dead spots??? Do I have too much flow??? Seen some people say around 20x is good..

No, you don't have too much flow.
Try repositioning the powerheads to blow across the surface of the rocks.
You could try a clean up crew that contains mostly detrivores. That would help some.
If you have water quality issues, try using a protein skimmer.
If your water is completely clean and pristine and you have no nitrate or phosphate, it could be phosphates leaching out of the rocks. Then you would have some hair algae buildup on those rocks.
You don't count the return pump as part of the internal flow rate.
Most people have to blow off their rocks anyways at every water change. It's good practice.
Also, I've seen this situation just go away on its own as the tank matures.
Good luck!
