Need some help. I'm really trying to figure out where my excess nutrients are coming from. I continue to remove live rock from the DT and put it down in my sump/fuge so that I can increase water flow in the DT. Today I took out a huge rock and busted it up and put it in the sump. Now my sump is completely full with barely enough room for my return pump and skimmer. There is prob 40 lbs in the fuge.
So here are my questions. How often should I clean the detrus out of the sump since I would have to remove all the live rock? I always see the LFS have rubber maids filled to the top with LR. I noticed that there is a lot of detrus on the LR in th fuge but they are"clean". Should that be blown off all the time or left alone?
Is LR really that functional in the fuge as a filtration? I question that I have adequate filtration since I have excess nutrients that aren't being taken care. Should I get rid of the LR and replace with cheato or a algae scrubber? If so will removing the LR screw up my benificial bacteria and or filtration capabilities?
My macro is dying in the fuge I think because of the start of GFO.
Curious and I know I've asked before, but can't recall what you had said, but what is your Phos level.....You say you have all but removed the LR from the DT, and still continue to have a nutrient issue......If your Phos is elevated, I would be curious to do a check on the rock and see if that is what is leaching causing your issues.....If the LR is the case/cause then you'd be left with bleach/acid bath....GFO would possibly work as well, but probably on the costly side as well.
As far as LR I'd keep the it clean and blown off....That IMO is a big key to husbandry......LR does play a factor/degree in biological filtration, but to what extent not entirely sure.....I question how important it is being that you can look around and see huge tanks done with "very minimal" LR and the tanks are very successful, so my logic would be not as important as some might lead us to believe.....
I don't see anything wrong with keeping some LR in the sump area, but wouldn't pack it full.....The GFO might be factor killing your macro off as well....Put some LR in a container of saltwater and aerate it and take a Phos reading......I'd be surprised if the rock isn't leaching Phos fueling your algae issue.
