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.
First few days in my tank was ok. Then out of sudden, the tube worm dun come out during lights on and only come out when lights off.
I have reposition it, suspected my flameback is nipping at it.
