Sps tank all in one vs sump

[3l3ments]

I am currently losing a battle in my 250g system and looking to down grade into a smaller tank so it's easier to manage. Looking at like the 60g or 80g nuvo's. Looking to still keep it sps dominated. Question is do sps do well in all in ones? Or is it better to buy a drilled tank and sump it.

Question? Why you losing the battle on your 250G.
Do you have any pics?

In the past couple months my acros are dying and I can't figure out why I also test my water twice a week and everything been stable. I have increased the amount I do on water changes but things are just not getting better. Alkalinity is staying around 9 and calcium at 380. All other lvls are where they should be. Have inspected for pests can't find any, but took them out and dip them anyways.

And it's not just the actors in the tank my chalice and other LPS corals are doing awful

Mg?
NO3?
PO4?
CA Its a little bit low, try bringing it up to 420-440.

Louisville,Ky? Maybe I can come over and help you figure this out.
What type of lighting is on this tank looks like T5 from the pictures.
The frag rack seems low in the tank.

I would look for stray voltage, or possible heavy metals leaching into the water? Hows your ro/di....have you changed filters latley?

 

[acropora4u]

question, how much and how often are you doing a water change and is it 0 tds ?

 

[3l3ments]

Havent tested my NO3 or PO4 but mag is around 1350. Running 250w radion 20k MH. My filters look fine but I'm changing him out today my tds is reading 1, and I do about 60g a week

The frag rack was low cause I just got them in day or so before that picture.

What is this stuff?

If the tissue is sloughing off, then it Looks like the Beginning of Stn/rtn. As suggested above. Look for possible stray voltage or the possibility of heavy metals.

But rule out no3 and po4 first and then go down the list

I have a small 20g nuvo that I might transfer them into tomorrow after I do a large water change on the 20g now that I replaced the filters on my RO DI system. You think that would be a good idea?

 

[nemo1017]

Couldn't hurt;but before you do that, test that batch of water.

Couldn't hurt;but before you do that, test that batch of water.

I am going to let it run for an hour or so tonight to wash the new filters out a bit then test my tds meter tomorrow and see what I get

 

[ejazzle]

Test for heavy metals. Make sure you aren't using any expired supplements either. Put one of those poly filters in there and pray it doesn't turn blue lol

Alk?

If you are putting the corals into a new tank make sure to acclimate them slowly to the new tank water. Drip acclimate them for a couple of hours into the new tank water.

I agree with this.
I think they looked paled out. First, I would test for and rule out the simple obvious things.
They may be starved. Chalice and lps require more nutrients. They may not be getting it if you are doing 25% weekly water changes and not feeding enough.
