So update , nothing major this week. Everything just ticking along.
Fish , all good, I had a clown problem but she's now starting to fatten up again.
Blue spot. Still doing well, he's had a new challenge this week in the form of an engineer goby invasion, but he's holding his own, Not sure what to say with regard to engineer gobys. I like them but they do tend to move around the tank and kick out any fish that Is in the way, that being said I never see aggression , just pure Bulshyness !
Corals all seam to be ok - I've had a pearly bubble start to recede a little and a couple of things get dislodged and fall on to other corals which has caused a little damage to a couple , but apart from that looking good. Spa seams to be doing very well , growing nicely. I am a little worried about the colour of one it may be browning out , worry white when I had it now bright green with the blues on , but more brown with daylights , not sure if it's recovering or getting worse. Never kept spas before so no real point of reference.
Equipment - had a radion fail, second time for this light , no problems with the others just the one but radion are replacing it for me , very good service. I have also championed the rollomat , I do love this..... But .. Over time I am not sure of its robustness for salt water. Electrical contacts corroded. Motor intermittent on the float switch, motor no longer powerful enough to drive a full mat, and very difficult to clean and service. All that being said it does strip out the larger waste particles , keeps water clean and no filter socks to change ( I change the mat about one every three months). So good product but needs tweaking .
Dosing - I'm now doing calcium and magnesium . No real difference in the tank or corals I am just doing it because I think I should be. I am having a mystery with my alk. It's always around the 9 to 10 mark, but I never buffer it ? Originally I was a using calk , but I have stopped using this and it's still high. Anyone got any ideas why ? The only negative effect of dropping the calk is my ph was 8.1 to 8 it's now running 8.02 to 7.95.
Pest . Aptasia and bubble algae, I may have a small improvement on the bubble algae, but I've now had an aptasia explosion. Think I'm going to try and get the slug that eats them and see what happens , tried aptasia X but they just come back in the same place only larger.
Going coral shopping this weekend , Aussie shipment in . Hoorah !
