Hi Guys
Over the last 4 weeks or so my tank just does not seem to have that luster it used to have. I hope that makes sense but it just does not feel right. I have also started to get a small outbreak of Hair Algae that I need to scrub every 4 days or so, and then there is the Cyano. It is showing up all over the place and there are bubbles on nearly all the rocks in the tank. This stuff is even floating to the top of the tank and making like a film on the surface.
My params seem to be fine:
PH 8.5
kH 9
Ammonia 0mg/l
Nitrite < 0.1 mg/l
Mitrate 0 mg/l
Phos o mg/l
Calcium 520
- I have moved my light pendant up about 5cm.
- I have increased the flow from the return by driling bigger holes in the spray bar and letting the pump push as much as it can.
- I have added a new powerhead in the one back corner pushing 1200l/hour across the back of the tank. Moved one of the existing circ pumps to face the front of the tank and I cleaned both circ pumps which seemes to have increaded flow quite a lot.
- I harvested my calerpa out of the fuge (and unfortunatly let a lot of the crap get back into the main tank by mistake)
- I am curently running floss between the fuge and return to catch as much of the junk as I can.
I am worried about the crushed coral sand bed in both the fuge and main display.
My idea is to first redo the fuge so my question is, would it be ok to empty out the sump, clean it up and replace the crushed coral with play sand as more of a DSB. I will put the live rock back that is currently in the fuge.
Once I have done that, I would like to do similar for the mian display (after about a month or so). Move everything to a container, clean the tank and replace the crushed coral with play sand and then put everything back.
At the same time as I do the main display, I will put a power head with a spray bar at the bottom back as a sort of closed loop to create a circulation at the bottom behind the rock.
Possible or stupid idea?
Thanks,
Ross
