Sps corals bleaching from bottom up

[Acskippy]

That is... a lot.

I also pull about a tennis ball sized clump of slgae from my scrubber every 2-3 days.... barely got enuff to fill a ping pong ball after 3

Necrosis top down/Burned tips usually related to Alk swing. Necrosis from bottom up usually related to bottomed out nutrients.

I've lost many from the bottom up and not even close to bottomed out nutrients.

So strange, some fine, some completely gone... dont have pic cuz its night but im sure its because the hardier (cheaper) species can deal a lil better than the expensive ones

Throw the chemipure in the trash
I would throw the biopellet reactor in the trash as well, but the back shelf of your garage would work just as well. Carbon dosing and gfo are for heaaaaaaaavy input sps systems. You don’t need them if you’re only feeding 1-2 frozen cubes a day. My system is 50g and I feed 3 cubes, 1 sheet of nori, zoo and phytoplankton and ab+ reef energy. No carbon dosing, gfo, algae scrubber etc. Just a skimmer that’s on 12 hours a day and chaeto. No3 25-35 and po4 0.10-0.20

I never said it was from bottomed out nutrients.

You probably lost them from gfo or phosguard

Nopox is an sps killer as well

Chemipure was thrown in trash bout an hr ago and the gfo is off as well!! Hahaha

Dont use either

 

[Acskippy]

Scrubber, skimmer, chaeto

 

[Charlie’s Frags]

I was speaking to Gordonm

 

[Acskippy]

Iodine supp and mineral supp but been using that combo for years, esv 1,2 and mag

 

[Charlie’s Frags]

Just to prove 25 no3 and 0.20 po4 doesn’t kill sps

That's fake news...lol

I am not sure I agree that nopox, chemipure, Vibrant, and other items are always detrimental. Usually, people start using these types of products because a problem already exists and has become more noticeable. Coincidental that we start adding a product but do the Corals continue to show die-off because the irreversible damage has already occurred prior to the remedies?

 

[Sallstrom]

NoPox, bio pellets, phosphate remover etc, can all be used with success or have a detrimental effect. All depending on how and when they are used.
The other once mentioned I don’t know the ingredients in, so I stay away from them for that reason(which is a good idea IMO ).

Small frags are sensitive. Perhaps you got to too low nutrient values, perhaps they where not thriving for other reasons. You can’t always say why they don’t survive. Or at least I can’t

 

[River Lotus]

will a sudden decrese in light cause the same issue ?

 

[schuby]

I read somewhere on here that iodine helps prevent SPS corals bleaching from bottom up. I add a few drops of Lugols each week or two because of this.

 

[Charlie’s Frags]

That's fake news...lol

Dang. They’re a lot bigger now

Everybody is going to need to understand the difference in availability and residual levels to make this thread work. First, you need to understand that coral would much rather get nitrogen from ammonia or ammonium since processing no3 to get the n is costly, takes a lot of energy and is not efficient.

Availability is more important than residual levels - availability is usually what is in the water right now that has not yet made it all the way through the N cycle (plankton, ammonia/ammonium, etc.). Availability and higher residual levels are not mutually exclusive. However, if you are using a lot of media and chemicals, you can have very low availability and have higher residual levels still... this can be bad in some cases. You can also have very low residual levels and high availability - most tanks with lower residuals have this (zeovit, mine, etc.).

Everybody worries about residual levels since they have tests and stuff, but this is not where the prize is. Availability is what makes things run. Even people with higher residual levels are running off of availability even if they do not know it. I know that people like to post and talk about their N and P numbers, but this is like talking about horsepower only and not torque, gears, car weight, oxygen level, etc. when you are wondering if your car is fast... nearly worthless. Availability is harder to gauge and you have pretty much just feed a ton and then also export a ton to where your residuals are not rising - basically, use your residuals to double check your availability.

Using chemipure, GFO, LC, organic carbon, reactors of all kinds is OK as long as the availability is there. This usually required a LOT of feeding and a lot of fish. When I say a lot, I mean the kind that few people have, especially in small tanks. The mistake that people make is that they think that the application of all of these things is universal and this could not be farther from the truth. Using them is not universal and suggesting that people remove them is not universal. However, the suggest to remove them is usually more safe than adding them.

To wrap all of this up, if I posted that I was having X or Y trouble with my tank and then said that I had .1 residual nitrate and .01 residual phosphate, I would get no shortage of people telling me to raise my N and P and probably not one asking about availability. This is not helpful to most people and is too simple to do any good.

Update.... have now lost 6 sps... HOWEVER, i went back in my notes and noticed that i did 1 thing.... turn my biopellet reactor back on... didnt feed for 2 days after... nit and phos were very low (0.02 & 2-5) before biopellet... also added chemipure blue at same time... tested nit n phos today, 0’s for both.... could this be the culprit?

too many changes at a time

Best post so far in this thread.
