Firstly another equipment change to report. I finally decided to change out the Beamswork EVO refugium light for a Kessil H80 Tuna flora. I had been considering replacing it for quite a while now, not because I was unhappy with the light but because the metal stand was rusting in all four corners where it sits on the top of the refugium. I'm not sure if this has caused any metal contamination in the tank yet or not but I wasn't happy with the situation so it had to go. The reason I opted for the Kessil is because it's pretty much the only light that I could find small enough to fit over the refugium, everything else was either too big/long and would have caused a huge light overspill issue or excess heat in the small sump area. To combat at least some of the light spill produced by the H80 I have added a small piece of black acrylic sheet between it and rest of the sump. The red light is something that does take a bit of getting used to but if the macro algae grows well under it then I'm happy, time will tell.
Now for a Fauna Marin Skimbreeze update. The FM media lasted two and a half weeks before needing to be replaced, about the same amount of time as the most recent ATI 1l disposable unit. I'm not that keen on the design of this reactor itself as air is preferentially pulled from the side the outlet tube sits (as can be seen in the photo below). So when changing out the reactor some media is still unused. I think I will try rotating the cylinder next time to see if I can reduce the problem. To refill the reactor I used the Spherasorb media, it looks exactly the same as the FM stuff but costs a lot less.
As for the livestock well everything is ticking along. Acropora growth is slow to nonexistent thanks to the red bugs but at least they are not dying. The exception to this is the A. hyacinthus which seems fine (with a rather odd growth shape it must be said), I've accidentally fragged it with the algae magnet a couple of times now because it's growing too close to the front glass.
The Utter chaos zoanthids are becoming annoying as they keep detaching and floating around the tank ending up in spots where I don't want them in or sucked on to the powerheads. Since I don't have anywhere to place frags (and hate the look of frag racks in the DT) I've chucked the loose ones I've found so far.
The sun coral is still releasing planulae and I keep finding baby polyps popping all over the tank. The more I look the more I can spot, they've even settled out on the clam shell. The larvae are fascinating to watch, tiny orange tear shaped blobs that wiggle around the tank until they find somewhere to settle out. It's very cool!
As for the Balanophyllia now living down in the sump, I can't decide if it's doing better or worse. There is one thing though, I happened to knock it over whilst trying to feed it and when I set it straight again I noticed it has some tentacles poking out the back, my initial response was Oh ****! Aiptasia!! But on closer inspection it actually looks like a baby Balano bud. I'm not sure if this a good sign or a bad one? Is it failing so badly that it's sending out buds as a last ditch attempt to survive?? I surely hope not.
I'll sign off with a few photos.
And finally a FTS..
Yesterday I (along with the assistance of my better half) installed my long awaited shiny new GHL Doser 2 SA pump. No more manual dosing for me, yay! This piece of equipment is seriously snazzy, it feels solid and it just looks so very, very cool. I almost wish I'd got it sitting in full view; the light show it gives off is seriously impressive. It flashes violet, red, yellow, green, white or blue depending on its status. It reminds me of my teenage disco days lol! My only disappointment with the unit so far was the lack of a UK plug. Why?! The Mitras light has one so why not the doser too?? Very annoying indeed.
The initial set-up was straightforward and I especially enjoyed calibrating the pump heads, it made me feel like I was back in the lab again. Programming the dosing schedule through the GHL Control Centre was easy too. However where we fell down was trying to connect the doser to our home wifi network and then on to the myGHL Cloud. The disco light was supposed to turn blue when connected but it resolutely stayed blinking white no matter how much I shouted and pleaded with it. We did get there in the end after we double, triple and quadruple checked the instruction manual and all the data required (IP address/password info etc). I'm not sure I would have been able to sort that bit by myself to be honest. Good job my other half is useful with a computer.
The doser and dosing containers are situated in the cabinet next to the tank along with the ATU tank. Presently I'm using it to dose Tropic Marin balling salts (A, B & C). One pump head is currently redundant but I'm fairly sure I'll find something extra to dose at a later date. The liquids are dripped into the return chamber of the sump. Since space is severely limited inside the cabinet (with the refugium tank in place) I swapped out the Reefloat Sensor sump mount for the new Reefer mod. This was very easy to do, rather like changing a plug. Now the dosing tube holder sits where the sensor sump mount used to be, all very neat and tidy, well sort of if you ignore the spaghetti junction of tubing and power leads down there.
I always love to check out what's happening is the sump/refugium areas. The refugium whilst not particularly successful at growing lush macro algae, is at least good for cultivating amphipods and has a healthy number of spirorbid worms growing on the glass (as does the back wall of the DT to be honest). I was pleased to discover last week that at least one of the three mini brittlestars that I introduced as part of a refugium pack in December is still alive and and much bigger too. It's the first time I've seen one since the week of introduction (8th December 2016). Interestingly I discovered a sycon sponge has settled in the sump on one of the siporax rings, I think this is a good thing rather than bad.
The tank is now just under 10 weeks old and all the equipment is finally up and running bar the dosing pump for Balling salts (that's going to have to wait a while as I'm currently penniless at the moment).
The sump has changed quite a bit since the initial set up photos were taken. Within it now resides a Deltec SC1351 skimmer, a Schego 200W titanium heater, a Tunze 1073.02 return pump and the sensor for the Reefloat ATU-pro3. Additionally it now contains siporax in three separate baskets, two in the sump and one in the old ATU tank. Altogether they contain 5l of media and will be cleaned on an alternate basis to minimise disruption to the bacterial colonies. To the left of the sump sits a DIY refugium, it's a bit of an odd shape, tall and narrow, it remains to be see if it will grow algae efficiently or not. It is lit by a Beamswork Evo 6500K 18W LED on a reverse cycle to the display tank. Presently it contains a layer of Tropic Marin reef mud and a variety of macro algae (Cauperpa prolifera, Caulerpa serrulata, Chaetomorpha and a tiny bit of C. racemosa that sneaked in with the Chaeto). Both the refugium and the old ATU tank are supplied with water from the overflow via a small Eheim pump, they have been fitted with bulkheads to allow the water to flow back down into the sump and up to the display tank (DT) via the return pump.
I have removed the filter sock and to begin with I ran the tank without any form of mechanical filtration. Recently however I decided to add a bit of filter floss as I was starting to see increased levels of particulate matter in the DT.
The electrical sockets are sited away from the tank in a cabinet to the left, along with the RO reservoir for the ATU.
