Frogspawn Issue

well so far without dosing which I have not to this point levels seem to be pretty good

calc anywhere from 330-360
alk 7-10
mag 1260-1320

It of course changes between water changes, maybe if I step up and stay weekly I can get by without dosing for now.

Do you know of anyone using epsom salts to get mag up?

you know though I could just do a water change and test again

 

I think maybe member Kevin. I have heard it's pretty common so a google search "epsom salts to bring up mag in SW aquariums" should bring up a wealth of knowledge.

 

thanks a lot for your help!

 

My pleasure. Please report back with results as appropriate, it's always nice to see if anything or everything makes a difference.

 

Personally, I don't think your levels are the problem. Unless you are keep a whole tank crammed with hard corals water changes is more than good enough to keep parameters where they need to be. I have my 10gal crammed with hard corals and I don't dose... ever! 5 LPS (3 of which are spawns) and 6 SPS. My levels are around the ones you have. The fact that none of your other corals are being affected, especially your other spawn, and that it is only ONE head of the spawn that is being affected doesn't point me in the direction of a parameter. Your Mag being slightly low isn't low enough in my opinion to affect a frogspawn. They are very hardy and can tolerate swings in some parameters. Try doing a water change and get a low turbulant flow going to that spawn and the other one before it starts happening to it aswell. That fact that it is only one head on that spawn that is acting like that is pointing me towards a flow issue and that one head may do a bail out soon or just die off. It seems that when it's a flow issue that is killing the coral each head will die off or bail out one at a time before the whole coral dies.

 

I will def try that with trying to get a more turbulent flow tonight, the wierd thing is this, I have not changed the flow in the month that the heads have been in the tank, does it sometimes take time before you start to see the result of something being wrong, ie it has been fine until now?

 

Yea, that sounds about right. Well, in the tank they were in previous to yours most likely had a different direction flow or a turbulant flow, so when you placed it into your tank, to the coral, it was another different kind of flow so it remained happy until it realized that the flow was not changing. Some spawns take longer than others to be affected. Yours took a month, my first spawn took about 2 weeks until I found out what was wrong. Some have taken 2 or 3 months... it all depends. This can also happen if it's in too much flow. With my experience I have noticed that spawns are most happy in very low turbulant flow that is just enough to move the polyps/tenticles that is a mix of very low/low/modeate... hard to explain... but if you collide to different flow sorces corectly you can get a flow that will soot out a mixture of very low/low/moderate flow at random times. That's what I have (took me forever to get it right LOL) and my spawns are getting huge! My pink tipped has about 6 or 7 buds all around it.

 

thats great, They are in a low flow area right now but they are one direction though, so I will turn the cannister return towards a power head and see what happens!

thanks again

 

karma to you and corraline for your help.​

 

ok good luck! you might be there for a while unless you are VERY lucky LOL If you have a canister that has a flow adjustment nozzle like a fluval does then it will make it much easier. That was you can lessen the flow from the canister so that the colliding flows aren't blasting the spawns LOL My tank is a little 10gal so it was quite difficult for me to get a turbulant flow that wasn't too strong lol I was there at one point for about an hour slightly tweeking to get it right lol. everytime it comes time for the power head to get a cleaning I have to do it all over again LOL it's a pain, but in my opinion it's worth having healthy corals lol.

Oh and thank you!
