Hmmm... Dun quite get what u mean, how does that help to check for dead spot? The only dead spot I can find is perhaps in the middle between the 2 structural rocks but I can't place any wavemaker there.
Noted, thanks for the advice. I putting them nearer to my wavemaker. In fact, I think my blue Mille is doing better than my green one in term of visible PE.
If it is the case, I bring a cup of my tank water for him to taste, maybe he can also taste & tell the levels of the other parameters, ca, kh etc... Will help save $ from buying all the expensive test kits, lol.
The blue mille, I cut out the base rock it is attached to and glued it to my structural LR. Also accidentally broke one of its tip,
now the base looks a bit ugly. Hope it can recover and encrust itself to the rock.
I's been a week and I'm really pleased with the work rate of this baby. However, I've adjusted the water level to the minimum and I still get wet skimate.
The recommended water level is between 120 to 240mm but my sump water level is appox~300mm. I tried elevating it but the water level inside the cylinder becomes extremely low. So decided to just leave it as it is right now.
