After waiting absolutely ages for delivery I was finally able to set up my shiny new GHL Profilux 4 controller over Easter. The hope is that when the time comes I can monitor the tank whilst I'm away, so less worry for me. At the moment I just have it set up with four probes measuring temperature, pH, redox and conductivity.
There is just 0.1 degree Celsius difference in temperature readings between the digital GHL probe and the Simplyaquaria temperature controller which is pretty good going considering the price difference between the two. I am going to keep the Simplyaquaria controller running as a backup to the GHL, two alarms are better than one in my books. I may actually move the Simplyaquaria probe to the DT so that I have two separate temperature readings to compare.
The conductivity of the tank water measured by the GHL probe was 51.8mS which converts to a specific gravity of 1.0257. My calibrated refractometer measured it to be 1.026, again the values are pretty close which is good. I am happy to know that I've been maintaining a suitable salinity using the refractometer.
I never bothered to purchase a pH test kit this time round so I had no idea what the actual pH readings were going to be. The levels are fluctuating between 8-8.2 or thereabouts, I would like to study the whole 24hr cycle but haven't managed to work out how to access data from the Profilux yet (if indeed it's actually possible to do).
The redox probe is still bedding in, to be honest I'm not really sure what to expect from the readings as I've never used one before. It came with the set so I thought it'd be interesting to set it up and investigate what it can tell me about the tank.
On the livestock front, Charlie the hitchhiking hermit crab is now on borrowed time after his first tank misdemeanor yesterday. He knocked my prize Acropora gomezi frag off the rock in his quest for food. I supposed I should be pleased that he just wanted to graze off the rocks and not eat the coral but still it's annoying. He's really quite big now so I'm sure that he'll cause more trouble in the future if I don't try and catch him now.
I think the T. nudus gobies have spawned again, Hop has been sequestered in the cave for the last two days and Skip won't let him out to feed, so I'm hopeful that there are eggs hidden inside. I hope I actually get to see some fry this time round, pretty please! The Cardinals also appear to be courting but there's been no further release of eggs.
So far the corals (and clam) that I have purchased from my (sort of) LFSs have arrived with 'extras'. Aiptasia, nudibranchs, pyramid snails & red bugs. The corals I have mail ordered from Reefworks however have been hitchhiker-free, so it was a kind of a no-brainer who to choose for my next additions. On Friday I took delivery of some lovely new corals. A beautiful frag of Oxypora sp., so well encrusted that the frag plug was completely hidden, it's my new favourite coral. A frag of Cyphastrea sp. "Meteor Shower", also well encrusted although I would have preferred to have been able to remove the frag plug entirely for positioning onto the rockwork. It looks kind of unnatural at the moment but hopefully it will 'grow in' given time. I also received a frag of Acropora sp. "Red Dragon", and a frag of Acropora sp. with purple tips (but is currently not purple at the moment), plus a frag of Red Tuxedo zoanthids. The zoas are still settling in so I don't have a photo of them yet and the I'm still working out how to take a decent shot of the "Red Dragon" (the bloomin' Welsh Dresser gets in the way. It's going to have to go, lol!).
Whilst I had the camera out I snapped a few other shots, more to follow including a FTS later in the week. Acropora sp. #2 that I treated for red bugs is now looking much happier with good PE. Acropora sp. #3 with the blisters is actually showing some improvement, a couple of the blisters have burst and the wounds are healing nicely. I think it's on the up and up now.
For the most part the tank is doing OK. There is very little in the way of nuisance algae, the furry stuff that was coating the rocks seems to be fading away without any intervention on my part. The zoanthids are opening up nicely and looking good, so I think the nudibranch problem is solved. The LPS expand nicely during the day and are always ready to eat whenever they sense food in the tank.
Most of the SPS corals are doing well, showing good growth or at the very least basing out. Colouration however is not great for some of them, I'm hoping that with time and stability the colours will improve. Maybe it's a nutrient issue?
There is one Acropora sp. (#3) that does not look good. I have noticed recently that there appears to be blistering to the flesh. This is a new one on me so I did a bit of searching on the web and others have reported this ailment. Unfortunately no one really knows what causes it. Some say that it's due to an imbalance with the big three, i.e. KH, Ca and Mg but in my case I have those parameters well within recommended levels and they haven't fluctuated much either. The only suspect I can think of at this stage is KZ Sponge Power, I began dosing this on the 11th February (1 drop every other day). It may have nothing to do with the problem but I think I'm going to stop using it for a while and see if the Acro improves.
I nuked the tiny Aiptasia that sneaked into the tank on the clam shell with Aiptasia-X and didn't feel bad about it at all. Now I just have to be vigilant for more Pyramid snails. My list of hitchhikers found in this tank is growing ever longer.
I'm happy to report that the fish are all doing fine. It's been just over a month since I added the Pink Streaked wrasse and I'm thinking that the time might be right to introduce some more soon. This time I definitely want fish that will swim out in the open. I have fish that hug the rockwork, that sit on the sand and one that hides in a hole in the sand, I really need some bold fishies that aren't shy!
The new corals have been fixed in place and are looking great, I just hope I can keep them looking as good. I had to move the Lobophyllia as Lurch the conch kept barging past it and knocking it over, it's well away from the Acanthastrea now so there'll definitely be no coral warfare between those two.
Also, and try not to laugh too much, but I managed to take a quick video of Gordon the Whitecap goby and Al, his pistol shrimp partner. Al had decided to rework the 'wall' yet again giving me the best chance of capturing them on camera. Unfortunately I had to position the camera downwards to see into the hole so there is some glass distortion and I've never taken a video in my life so there's that, lol! Still you can see that they are alive and doing their thing.

Up till now I have avoided ordering corals through the post but this week after seeing one of my 'wishlist' corals available online and checking the shop reviews I decided I should give it a whirl. Boy am I glad that I did, the frags arrived yesterday from Reefworks and they look great, easily as good as those that I have driven to the LFS and picked up myself. The colouration was excellent right out of the bag. The coral that I really wanted was the plating Acropora hyacinthus (red planet), this growth shape really speaks to me of reef. Naturally I couldn't just order one coral so frags of A. gomezi and A. loripes were also added to my basket along with a gorgonian for some movement. I'm not sure that they would necessarily be found together in the wild but my tank is quite static looking at the moment and they apparently can take a blasting in regards to flow so hopefully it should fit in quite nicely with my set up.
I'm pretty much set up for SPS corals now, maybe I could squeeze one more in along with something encrusting perhaps. I am happy to say that the corals that I have all appear to be doing well either basing out or growing at the tips, I expect that I'll need to keep a close eye on the KH levels etc now, the extra corals are bound to suck it up quicker. Now I just need to find that perfect clam...
