My green bubble coral and frogspawn are both sulking

[Toni1984]

Hopefully someone can help as both of my stonies are struggling and ideas just wondering if there is something that i need to feed them or do different for them.
Many thanks

Pictures, water parameters, flow and age of tank will help to answer this question

 

[Toni1984]

Oh ye sorry
Nitrates 10
Phosphates 1.025
Ammonia 0
Ph 8
Calcium 450
The tank is 14 months old
The flow for the bubble is low with low light and the frog spawn is moderate flow and moderate light, they were fine for months but all of a sudden they seem to be struggling

Is that really your phosphate level?? Or is that salinity? Really hoping that is salinity.. because that would be one heck of a phosphate number

Well first things i see as problems are that you have 10 nitrates which is a bit more then what LPS usually like.. They should be probably less then 5 but you should still have a few ppm of nitrate, 0 Nitrate is bad. Then phosphates look like a big issue there... 1 ppm of Phosphate is very high and should be kept around 0.030 ppm. Unless you mistyped and meant salinity. Also please include your Alkalinity that is one of the most important in keeping corals.

 

[Toni1984]

Ha sorry ye that's the silinity
Phosphate is 0

 

[Toni1984]

Alkalinity is at a steady 10

Are these corals new to the tank?

 

[Toni1984]

No they've been in there for around 4 months and been growing nicely. This is what I don't understand what's changed

The frogspawn definitely doesn't look happy. Possibly brown jelly disease. The bubble looks like it isn't all THAT bad. Sometimes corals deflate and then reinflate on their own.
If nothing has changed recently, temp, ALK or salinity, then you may have just keep an eye.
LPS corals like things a bit dirtier than do SPS. Personally, I think nitrates should be in the 10-15 range with phosphates low, but detectable. Like the 0.03 range.

I may need to get some better testing gear. I've got some monti also and it seems to be doing well and growing nicely also. I may just be my clowns that have damaged the frog spawn I've moved it to a different side of the tank and got them a bubble tip do hopefully it will be left in piece. Thank you for the advice

Toni, where are you located? I lost a bunch of coral for an unknown reason as well during your time. I found out that where I am (LA) the water source was changed and was coming from the ground now (because of all the recent rains) which happens to be nutrient rich and my RO/DI wasn’t enough. I have since our heat an extra three stages of DI ‍
