Okey guys, an update, and a little sad one at that:
This NPS tank is no longer. Financially I was unable to do 50% water changes per week, and the corals slowly deteriorated a bit. Another issue I had was that feeding them proved almost impossible with a Copperband Butterfly in the tank, as he would steel the food quicker than I'd eat, and this some times went together with sun coral polyps beaing torn off by the Copperband's skew aim.
As some may know, I also got a shipment from Lanzo of four suns (2x Tubastrea Faulkneri, 1x Tubastrea Micrantha (branching black) and one unidentified branching orange sun.) I went to pick them up, and between Gauteng Road agency and a broken clutch cable they were bagged and in a 37deg Celc car for 7 hours!!! This was not good.
This, together with deteriorating water params made the two branching corals starting to fall apart, and the high temp also cost me half a sun coral colony.
Then I had to make a plan, as I could not let everything die.
I broke down the arch, got myself a 2foot tank, and moved the NPS system to a nano NPS system. This allows me to afford 50% water changes per week, easier feeding and no hassling fish. Flow is also better on the smaller tank, so detritus can be sorted out easier.
Still no skimmer, but I am considering a HOB skimmer, as my total tank volume is about 60litres only. The new tank has a DSB, and the algae scrubber from the original tank. Since I have done this move ( a week now) my NPS have started opening again, feeding, and even the branching suns are doing much better.
The branching suns did not open at all for four weeks, and feeding them then is impossible. I have now moved over to target feeding on a next level, and that is feeding with a tweezer. Here is a stunning photo of the very first black suncoral head tanking a mysis shrimp.
This was two nights back, and last night I counted 10 open heads!!!!!!!!!!!!! Seems I might be able to save them, and I will keep on tweezer feeding them for another month or so.
Here is a photo of how it looked on Sunday evening, and you will note the tissue die-off happening. I am however confident that it will heal again now that it is feeding again.
Here's a close-up of the rare orange branching, and I can not get the polyps to extend more than this as yet, so feeding this baby still is quite difficult, but it took about 3 mysis last night, so it will slowly regain it's strength.
And here is a "bad" FTS of the nano, I will try to take a few better shots and post:
As for the original tank... It is now a softie and LPS dominated tank. I plan on keeping "easier" corals and fish, and have the Nemo and Dorry in there for the kids.
I will create a new thread for that tank when it looks nice again.
