Tip recession and Fe(rust)

[BLKTANG]

any new growth?

Woah 2 years,man im sure i could learn a ton from u,have u read the thread on zeovit forum about the older zeo tanks,& sterility?

 

[7thheaven]

Thogh I am running about 2 years, I changed my tank in last year so my tank is just 1year and 3month old...

Hey Vince, sorry to hear about your problems. Did you ever use RB salt? What's your start2 dosing?

I don't think it's your alk or potassium. I've been running zeovit since the beginning 7/2006. I used to use K bal. B bal. Alk 7 dkh. Right now I don't dose anything but the basic 4. I'm keeping my alk at 9 dkh without any tip recession.

You need to watch out for start2. Have you ever accidently overdose start2?

 

[7thheaven]

Thanks naka.

A few days ago I changed new version of zeo start2 from Pohl.

It is written 2ml of 250gal, and I dose 0.3x2 daily as Alexander recommend.

Do you have the better result after changing KH7 to 9?

At first I am suspicious about old food7 and start2 so I quit the dosing include bak but it is not work well either. so I found it is not problem because of this.

I heard from Alexander that New start2 is better than old one.
but not sure because I dose it a several days!!!

I gave up the RBS. I do not use it anymore.

I never had any problems w/ start2, but I dose very little. (3 drops/day) I know for sure that RBS (version 2) results in tip recession. That's why there is version 3 that's just came out for US. Can you get HW marinemix? I've been using it for last 3 months w/ excellent results.

Here's what I know w/ zeovit.

1) prolong overdose w/ Start2 = stn
2) RBS = tip recession
3) ALK = 9+ over 2 months w/ no ill effect (need more time)
4) Mag < 1200 results in Cal/Alk swings
5) Pappone every day = incredible growth

Although I do not run Zeo, I do not think it is related. I had very similar issues when I was running nothing(meaning Ultralith or Zeo)
7thheaven: do you by any chance have marineboard with a bunch of detritus and stuff caught underneath? Like I said, I am shooting in the dark; just trying to compare different things that both of our systems might have in common.

 

[7thheaven]

Thanks...

Naka~

I also have experience tip recession of RBS I stopped to use this
but After that, My SPS are dying...It may be coincidence...because I use just 2~3times water change 5% of total volume with RBS, it;s effect can be long until now?

I do not know about HW MarineMix. Is it from Germany?
Could you tell me the URL of this?

Dear rutz81~

Could you tell me more easily? I can not get what you wanna tell me cause of my not good Engllish..

I am using starboard or marine board on the bottom of my tank rather than just putting the rocks directly on the glass(for fear of cracking the glass) Many people use this when they run bare bottom. Anyway, mine seems to accumulate a bunch of stuff underneath and for the life of me, I can not get it out. I was just wondering if the phosphates, nitrates or something else is leaching out. Hope this makes sense.

I'm not sure if this is Zeo related or not also. My tank has been runing Zeo since 10/05, I'm actually on RBS v2, bucket #2 and have never had tip recession from using it. Odds are it was exsasperating an existing situation? I'd still lean towards metals at this point, Seachem Cuprisorb will also pull out heavy metals (despite being made for copper, it will pull out other heavies). Not sure if anyonelse knows of other products to remove metals....

[7thheaven]

Thanks..PW...

I am not sure either but I think it is bad batch of RBS. so Some guys have no problem but some guys have problem about this.

I know many people have same experience tip recession and gave up this salt. but I think this company do not admit this...
just thought....

Cuprisorb can help this thing? Do you think so? I can try this..

HW Marinemix

I get mine from Hawaiian Marine

PW, I need to correct my last post. Not all RB salt will cause tip recession, but there have been few incidents. I'm not saying RB salt is the reason for Vince's problem, but it could be one of the reason.

Few RB salt users (myself included) had tip recession problems, but since changing salt, the tip recession stopped.

 

[PrangeWay]

I'd try it. I run it in my tanks periodically just incase.

It will remove cadmium, iron, nickel, zinc, cobalt, cadmium, manganese. Also they know it'll remove other metals, but those are the only one they have tested data for.

Think one of their little prefilled filters bags of it runs like 10 bucks american so worth a try.

Thanks.

I read the url and it can absorbed the PO4. Abrupt many PO4 removal can be harm to SPS I heard... Is it OK to use?

How many should I need it in my 100gal?

Thats false. Abrupt P04 removal doesnt hurt anythign.


The Iron and Aluminum from phosphate removers are what hurt things.


If PO4 removal hurt things, you'd never be able to move a coral from a dirty tank to a clean one.

7thheaven - I am having the same problem now again. It stopped for a couple months then started. Here is what I think -

Recently change media in my CA reactor, caused ALK to go too high - 13 range. Did not notice recession at this level. Fixed reactor drip and now running ALK 10.2 and having die-off/stringing. Maybe just slow to respond to the high alk and now it's showing the signs of alk being high.

Testing MG with two different salifert kits, one shows my MG off the charts and the other at 1460. I wonder if MG is too high.

I am bringing ALK down slowly, and will being doing a major water change to reduce the MG levels today.

I also use Tropic Marin salt. I will be testing a new batch of mixed salt today to see what the levels are. It's a brand new bucket.

All the corals last time, with the exception of my tenius colonies all grew back the tips. The pics you posted, the coral died. I have a tort that is bad and some others with dead tips.

I have no idea what this is caused by. I still think it's either an ALK or MG issue. Those are the only two items that are out of range possibly. I keep this up to date.

hmmmm....I am using TM salt, too. But, my alk went really high too, just like you. Looks like we are in the same boat, I'll keep this thread updated on if it happens again. Haven't had any problems in like 2/3 weeks.

TM or TMPR?

 

[7thheaven]

I checked my cross fan if it can release rust or metal source.
but I think it is not source.

The equipment I have is.
1. cross fan upper the tank side --> no src
2. Tunze 6100, vortech
3. Octopus Skimmer
4. RD 65m for return
5. eheim pump for zeovit reactor
6. maxijet for Ca reactor
7. titanium probes for ground, temperature

Old or bad Ca media can be problem? I have granulate sand for
media more than 1.5 years during this, no change media~
There are less half of it in my CA reactor.

I ordered a granulate ARM media and would change it.
and I ordered also 2 x Seachem CupriSorb 100 mL Bag and
would give it a try.

I'm been using the regular TM. Get this though, when it first happened the bucket of TM I was using had little grey particles in it - some about the size around of an eraser head - and they were a clay-like matter when I rubbed it between my fingers. Also, when I'd mix water from that bucket some of salt would mix into a cottony substance that wouldn't mix ever. I finally stopped using the salt and could never get a straight answer on what it was. I switched from buying TM at the LFS to online (saving money too).

Also, I noticed my salifert MG kits are different and might be why I am seeing different levels. The old kit says 6 drops and the new one has 4 drops. When I test at four drops, the color never changes. Which do I go by? I'm gonna check it all later.

I have the same problem with my sps at the moment and I'm using instant ocean, it all started a month ago after using a 2 part epoxy, the only thing I can think of.
