Help with Frogspawn

[DD0513]

I will attach some photos, but I have changed nothing in my tank other than adding some microbacter7 due to a small cyano outbreak, my frammer has been only partially open for about 5 days now, color still looks good, but the coral just isn’t opening up. I attached photos of some of my other corals too just in case someone picks up on something similar between them. I am pretty new to coral. Frogspawn has been in tank about 3 weeks, looked great for first two weeks. I just did a 20 percent water change to help replenish calcium and other minerals. Any thoughts or suggestions would be appreciated.

How old is the tank? Can you share your parameters? What type of lighting and flow?

Frogspawn is not exactly a beginner coral IMO, it requires more stable parameters.

 

[Gumbies R Us]

I'll second with mojo

We need parameters, lighting, and flow for your tank
Anything that could be bothering it?
Age of tank?

I don’t have all of them, I know two days ago my ph was 8, temp 78, salinity 1.024, alkalinity 10, nitrite 0, ammonia 0, nitrate 20, I don’t have my calcium at the moment, will have to check it tomorrow. I use instant ocean reef crystals and do about a 20% water change every 10-14 days, my light is a fluval marine LED with blues turned to 90 and whites at around 35 and every other color is under that. The Frogspawn is about 2/3 of the way up in the tank Flow is maybe just on the lite side of moderate. I don’t have any other stony corals, just the corals pictured. I feel like sometimes the zoa looks like it’s “melting” but everyone claims this light is barely strong enough for the corals I have and they have grown and one has just added a second head in the last few days, the toadstool generally looks good and is growing. Xenia has gained a stalk and I’ve only had it for two weeks. The tank has been running since April. I don’t see any inverts near it, I only have hermits, a handful of trochus, a cleaner and peppermint shrimp, micro bristle. My fish are osc clown, Midas, diamond goby, mccoskers, gramma, firefish and two zebra barred gobies. Like I said, I was dosing micro bacter7 to deal with some cyano but I haven’t added anything else to tank. I have since slowed down on micro7 to see if it helps. Here is a picture of the spawn right now, and of the zoa and toad. I cannot get videos to work.

Melting corals usually points to newer systems where micro fauna diversity and population are not enough (yet) to feed the system. They “starve”

What phosphate? That’s the important one. Too much, too little you get some pest type algae’s.

Check that and ensure it stays .1ppm ish and stable.

Ensure all other parameters are on mark and not changing from day to day.

Well the soft corals are generally pretty forgiving in terms of lighting esp the shrooms. The frog is the most needing of good light and flow. As far as replacing Alk and Ca water changes generally won’t be enough especially in larger than small nano sized tanks. If you want stoney corals consider a 2 part dosing system plus at least magnesium. Microbacter 7 is just a bacterial aid. Shouldn’t affect the corals one way or the other.
Here’s a video of my hammers and frogs to give you an idea of flow and lighting

 

[Mr. Mojo Rising]

For success with corals you will need your own test kits, it’s an absolute must. Not API, get salifert or hanna.

 

[DD0513]

I do have my own tests I am not home at the moment.

I took a closeup photo, I can’t tell what the black spot is on the coral or whether or not the other small structure is a vermitid snail. If it is a vermitid snail should I remove it? The right spawn seems to come out about 75 percent or so of its original size now, the left one is still just kind of poking out slightly for most of the day. Calcium is 440 btw. Nothing seems to be fluctuating, I log my levels weekly and nothing has moved much at all in quite sometime. I did notice today my xenias are much more active than they have been now that I have stopped dosing the microbacter7. I noticed while dosing it, my diamond watchman starting surfacing and gulping air every few minutes. I am wondering if the bacteria was removing oxygen due to how heavily I was dosing it initially. I was following directions.

Your light is not strong enough for most hard coral.
