Everything seems to be ticking along nicely at the moment. The KH dipped a little following the addition of the carbon dioxide filter and I've had to up my dosing rate as a consequence. I'm hoping it means that the corals are happier with the higher pH values and have increased their growth rates. Unfortunately perhaps, also due to the dip in KH (down from approx 7.0 to 6.5), the coralline on the back wall took a bit of a beating. It's not a problem as such but clearly I need to keep a better eye on the alkalinity level.
Swipes the porcelain crab, Petrolisthes galathinus, has settled in nicely and is proving to be a star attraction with the rest of my family (after Lurch the conch, who still remains the absolute favourite inhabitant). She has made her home underneath the left-hand rock pile and spends the majority of her time hanging out with Edna & Kylie (the two wrasses), filtering out small morsels of food from the water.
Ming, the Pom Pom crab (Lybia sp.) has also settled into the left-hand rock pile, in a small hole, way under the ledge. He's still pretty shy and we don't get to see him out in the open very much as of yet, I did manage to capture a sneaky shot of him in his hidey hole using flash today however.
It's pretty time consuming trying to take individual photos of all the corals individually on the same day so there just a small selection below, I'll work on adding the rest later in the week hopefully.
To finish, I just have to share a couple more shots of Crystal the Red Spotted cleaner shrimp, Urocaridella antonbrunnii, because she is the most incredible looking shrimp.
This tank is approaching the 6 month mark (on the 16th April). Wow, where has the time gone to? It's now well and truly in the 'spotty phase', the back glass is covered with spots of coralline algae and spirobid worms. I have scraped it once already and am now in two minds if I should do it again. Does it look natural or does it just make the tank look messy? I can't decide, answers on a postcard please. :o)
I've had to move the Lobophyllia yet again. The Lobo was very happy in its last spot but, darn it, the snails (Mr Conch I'm looking at you particularly!) just kept knocking it over no matter how hard I pushed it in to the sand. So now I've glued the base of the skeleton to the rock work on the right-hand side at the back. It's not great for viewing but at least it won't get damaged there. Fingers crossed that's the last time I have to move it!
Acropora sp. #2 still appears to be red bug free and the PE looks good. Acropora sp. #3 is on the mend I think, to my eye there appear to be less blistering now. It's not completely out of the woods yet but I'm feeling a little more confident about its future. General coral colouration is not great but I'm not too concerned about that at this point.
My mysterious hitchhiking crab has thankfully moved away from the S. hystrix and has set up home in the uppermost right hand rock. I still don't have a decent picture of him to show I'm afraid, he moves like lightning whenever I get close. So far he's not attacked or eaten anything that he shouldn't, I regularly observe him scraping at the rock work with his spoon shaped claws and he does a great job of keeping that area clean of algae and detritus. He has grown considerably and I am probably not helping matters by occasionally feeding him directly. I have tentatively identified him as Chlorodiella nigra which is a member of the Xanthidae crab family. According to my research they are generally fine when smaller but can become troublesome as they grow and their appetite increases. I am investigating removal options just in case.....
Yesterday afternoon I introduced probably my last fishy additions for this tank, they are still settling in at the moment, pictures to follow hopefully later on in the week.
So my tank seems to have passed the first coral test, all of the frags I introduced 12 days ago are still alive. Phew! The Stylophora is even showing signs of growth. I think it might be time to add a few more at the weekend and maybe even another fish.
The coralline has really started to take off, I'm seeing spots of growth on the pumps and on the back wall too. I am undecided as to whether I should scrape it off for a nice clean look or leave it au naturel. I'll live with it for a while and see how I feel when the coverage increases. Spirorbid worms have also begun to appear in the DT and in the sump too.
The tank parameters as of this morning are:
Specific Gravity 1.026 d SG
Alkalinity 6.85 dKH
Calcium 425 ppm
Magnesium 1270 ppm
Nitrate 0 ppm
Phosphate 0 ppm
I'd like to tweek the KH and Mg up a bit more but those values are not too bad. I am extremely surprised not to have any detectable NO3 or PO4, this is a bit of quandary for me, I don't think I've ever had a tank with no (or low amounts) of NO3/PO4. I guess the Siporax and refugium must doing their thing, it is early days though and stocking is light I so expect that the levels will rise soon. I do have a bit of furry algae growth on the rocks and a film of algae forms on the glass so I know that there must be some nutrients hidden in there even if the tests say different.
