K: 420 ppm (Salifert)
Alkalinity and calcium consumption are at an all time low due to deforestation. Limewater is for the first time meeting the tank's alkalinity and calcium requirements almost exclusively in these days. I am adding only 36 ml part-2 daily, which was well over 100 ml per day when the tank was packed with staghorns.
I have started to dose KZ sponge power again albeit at a smaller amount (2 drops daily as opposed 3 drops ) to help recently cut frags heal faster and establish. I am getting more diatoms on the glass and rocks as a result due to suspected silicates in this product. My Coco worms and giant feather duster worm appreciate diatoms when I clean the glass.
Moreover, I have re-started TM Pro-Coral iodine dosing, which is essentially lugol's solution (elemental iodine), twice a week (1 drop each time). I suspect that I am overdosing iodine because the KZ A- elements I am using daily already contains potassium iodide and though I cannot prove it KZ Sponge power must have some in it too. Having said that I cannot see any detrimental effect on any animals so far including the fish.
Finally, here are some top-down photos I took four days ago:
The sarmentosa has settled down on its new location. Its polyps are extended throughout the day. One of the two acro crabs has migrated to the desalwii. The pink colouration on its tips is coming back slowly.
The granulosa's growth rate has picked up recently. There is less green pigmentation on it.
The microclados is growing at a mad rate. During the deforestation process I have decided to dedicate the entire live rock to it and thus removed the acro directly above it to prevented it from being overpowered by the microclados. There was evidence that it was going to lose the acro war (see the white tip stung by the microclados in the second photo below).
