campbell_wat Posted July 3, 2022 Share Posted July 3, 2022 Do you have enough flow on those zoas? It looks like there is some buildup on the mat. Im sure you know but rastas are among the pickiest and most temperamental Quote Link to comment

Im sure you know but rastas are among the pickiest and most temperamental thats what I was thinking. they're in a lower flow spot near the front so I was going to move them closer to my pump outlet and see if they perked up - but they were fragged off a bigger colony the day I got them home so I wasn't sure if they were sulky because of that/travelling/still acclimatising either. Worth a try though! 🙂 2 Quote Link to comment
InAtTheDeepEnd Posted July 5, 2022 Author Share Posted July 5, 2022 Ok so it WAS happier higher up. Till one of my arsehole hermits tossed it halfway across the tank. Sulking again now, which is fair enough I say 🤣 I'd sulk too if a crab used me as a volleyball 5 Quote Link to comment
InAtTheDeepEnd Posted July 6, 2022 Author Share Posted July 6, 2022 Just after lights on this morning I need to clean the glass lol There's some lil scypha sponges on my rock now too. As per I'll leave em unless they start taking over. Can't say I mind any of the hitchhikers tbh, they're just more interesting stuff to look at. Maintenance is still topoff once a day and WC every 1-2 weeks n it seems ok. Still experimenting with rasta placement but I'll get there. Gonna rehome my candy cane to the frag tank at work though probably because I keep forgetting to target feed it and it's got really skinny and sad, but that's my fault. 6 Quote Link to comment
InAtTheDeepEnd Posted July 8, 2022 Author Share Posted July 8, 2022 I think they could be out a bit more than they are but i literally just turned them the right way up from where the crab had tossed them, and then left them. So might see how they go tbh - they're bloody gorgeous. I do love zoas though 🥰 3 Quote Link to comment
InAtTheDeepEnd Posted July 12, 2022 Author Share Posted July 12, 2022 Acquisitions ..... Ten columbellindae snails and a green Monti (terrified about keeping the Monti alive lol). Have salifert magnesium and calcium kits and epoxy to hold it in place/keep it safe from vandal hermits, coming tomorrow though. Meanwhile my £5 blue shroom is encroaching on the rock next door. And there's two heads of rainbow zoa under the Kenya tree that id quite frankly forgotten I had lol but they seem fairly happy. 2 Quote Link to comment

The store where I work 🙂 We have a great selection of £5/£10 frags - not just softies but montis and things as well. My rastas were from there too though the manager just gave me those because he was fragging some stuff and they were too small to sell. The monti and palys were from there too. Monti free because it had fallen off the frag rack and was just sitting on the substrate, palys were £5 each. (less with staff discount lol!) But for the prices our frags are huge. Not local to you though unfortunately, it's Gloucestershire. If anyone more local wants anything specific I can ask about it and put it aside if we've got it. 1 Quote Link to comment
InAtTheDeepEnd Posted July 13, 2022 Author Share Posted July 13, 2022 Oh no!! Moved my Monti onto the central Island this morning and it bleached a little 😓 Put it lower down on the sandbed and its not lost anymore colour and the remaining green bits have brightened up again. If it stays ok where it is will target feed it on Saturday I think... Also tested my magnesium and calcium, with salifert liquid test kits; Mg was 1410ppm, Ca was 325ppm. Might raise salinity to 1.0265 for faster coral growth, it's currently 1.025. but I know my calcium is a little low and magnesium is a bit high. From memory the dkH was 11 or 12° last time I tested, and nitrate was about 5ppm, but I will check tomorrow. More feedback on my parameters would be really appreciated though. Need to do a full range of other parameters (kh, pH, nitrates) tomorrow - but I have COVID, so it can wait lol. Quote Link to comment
InAtTheDeepEnd Posted July 13, 2022 Author Share Posted July 13, 2022 However the other corals are happy. Just some teething issues with my first SPS I guess 🤷 1 Quote Link to comment

Need to do a full range of other parameters (kh, pH, nitrates)... 1.025 to 1.026 is good. Try to keep it stable within this range. Alkalinity stability is crucial for stony corals. I try to target the value of a newly mixed batch of saltwater, so that water changes have no effect on stability. The alkalinity level and stability is what's important, pH isn't usually very important to monitor. Some exceptions would be if you are doing something which might change it (like dosing Kalkwasser or running a calcium reactor) or if the room where you keep your tank has a high CO2 concentration. Phosphate is another critical nutrient level. Low nutrient levels negatively affect photosynthetic life and could potentially result in a pest like dinoflagellates, which are better able to thrive in those conditions (without the typical competitors). Get a good low range phosphate kit. Salifert's kit is adequate, but I prefer Hanna's Phosphate Checker (API's phosphate kit is a high range kit and therefore isn't very helpful for keeping most reef tanks).

InAtTheDeepEnd Posted July 26, 2022 Author Share Posted July 26, 2022 I guess the fact that I have nothing to report really in reef terms is good? But I have finally mounted the rastas on a plug. Hermits have touch wood been leaving the dove snails alone. Parameters are totally stable. Corals growing. Moving some of my zoas about I think at some point so they're together, then I'll probably grab some more of our £5 frags at some point from work. Some red mushrooms to contrast with my pretty blues would really pop I think. We don't have a great zoa selection so I'm thinking of getting some from Coralz, bit I dunno - I love watching my current corals grow and get bigger so might leave it and let them have lots of space to hopefully get massive. 5 Quote Link to comment
InAtTheDeepEnd Posted August 2, 2022 Author Share Posted August 2, 2022 One of my hermits has somehow got hold of a ramshorn snail shell and I can see a creepy amount of its body through it 😅 Aaah!! No idea why those are upside down, sorry 4 Quote Link to comment
InAtTheDeepEnd Posted August 6, 2022 Author Share Posted August 6, 2022 First major screw up in a while Water change Thursday, obviously didn't mix my salt up thoroughly enough because thought salinity was 1.025 but checked yesterday and got 1.020. Kenya tree is a goner and has been removed....gsp not sure on, everything else sulky but ok. Damnit! 😢 1 1 Quote Link to comment
seabass Posted August 6, 2022 Share Posted August 6, 2022 Any undissolved salt can burn coral tissue. But that's a huge drop in salinity. Are you sure you didn't do a water change with just freshwater? It would take a lot of freshwater to drop specific gravity from 1.025 to 1.020. I also question your test results. Swing-arm hydrometers are notorious for getting micro-bubbles on the arm, which make the results look higher than reality. Whenever you get a questionable result, repeat the test (that goes for any other test kit too). A calibrated refractometer should provide more accurate results. And, in theory at least, calibration fluid should give you the most accurate calibration; however, I've found that calibration fluid can be off, or become off over time. Therefore, I find that using RO/DI (or distilled) water to calibrate provides the most consistent calibrations. Dropping salinity quickly is typically less disruptive than raising it too quickly. To raise specific gravity, I usually just top off the evaporated water with saltwater until the level is back up where I want it. Sorry to hear about the mishap. I know that you are trying to provide a healthy environment for your marine life. You might be surprised how a coral can sometimes recover. Don't be too quick to remove unhappy corals. 1 Quote Link to comment
Snow_Phoenix Posted August 6, 2022 Share Posted August 6, 2022 Really sorry to hear about this - I went through this exact mistake just a few days ago and melted tissue on parts of my pavona (didn't mix the salt well, and kept dropping/increasing salinity to get it back to 1.024 too quickly). 😞 Seabass is right though - our reefs are quite resilient, and I wouldn't remove anything from the tank, no matter how unhappy it looks. Instead, just wait and observe, and also gradually raise salinity back to 1.025 over a day or two (don't jump from 1.020 back to 1.025 too quickly - because that'll stress out the animals even more). The kenya tree will be sulky for a while, but should recover once the salinity is back up and the tank stabilizes. 1 Quote Link to comment
InAtTheDeepEnd Posted August 9, 2022 Author Share Posted August 9, 2022 The kenya tree and gsp are sadly very definitely gone.....but everything else is doing good. I think my slip up with the salinity was a combination of things: I hadn't calibrated my refractometer in a while, I was water changing in a hurry so I took more than I intended to out, likely didn't mix up my salt correctly and also only checked the salinity of the newly made water once (normally I do it at least twice). There's also two large pieces of rock in there which I suppose may have affected things? (open to correction on that, I don't know in truth). So multiple places where mistakes were made/things could have gone wrong; in truth it was probably mistakes at several points in the process rather than just one! This is my bad but I have learned my lesson, sad it has happened at the cost of two corals (especially the kenya tree, that thing was gorgeous), and have now invested in a Hanna salinity checker too.

Generally alkalinity and calcium (and magnesium) are consumed in a typical ratio. Two part dosing additives were designed to replenish both alkalinity and calcium; however, you could just use the calcium additive. There are a number of vendors which sell two part additives like ESV, Red Sea, Seachem, etc. The calcium component is basically calcium chloride: http://reefkeeping.com/issues/2006-02/rhf/index.php https://www.bulkreefsupply.com/1-gallon-mix-calcium-chloride-single-use-bulk-reef-supply.html Quote Link to comment

I love the crabs but omg they are vicious little arseholes lol - they also like throwing frags. Quote Link to comment
