Mystery Solved

[griss]

Been losing Acro frags one after another for a month or so. LTA and BTA have not been happy. Lost several Ricordea recently and Zoas started looking crappy yesterday.

I’ve been looking, testing, looking, testing for a cause. Couldn’t figure it out.

My magnetic (in tank) frag racks were getting a build up of bubble algae and decided to take them out and found the cause. A razor blade that was mostly rusted away stuck to one of the inside magnets.

Put some Chemipure in the media reactor, have water mixing for a change and ordered a couple Poly Filters arriving tomorrow.

Hopefully I can keep this from getting worse.

Polyfilter delayed a day.

Went to Petco and they had Chemipure Blue so I grabbed some of that and added it to the media reactor.

Hope you caught it in time to prevent any further problems.

Thanks, me too.

Sometimes I wonder why I stay in this hobby. I went downstairs to get the dogs their breakfast (we keep their food in the basement) and there was water on the floor. Somehow, the skimmer got moved and was holding the float valve for the topoff down flooding RODI into the sump. Salinity in the tank is down to 1.020. Had to leave for work so, I can't do anything about it until I get off work tonight.

I have a glass of rusty nails that I use to dose iron. So far, no problems, even though I realize it isn't very scientific.

I have done a lot of diving on rusty shipwrecks, and the corals grow better there than in the surrounding waters.

Catastrophe averted?

Yes, I’ve been slowly bringing the salinity back up this week.

As a side note, since finding/removing the razor blade, my LTA that I thought was a goner appears to be recovering.

Nice!

I have a few thought experiments for you.

You buy a sea animal and it comes in water that is in 1.016 salinity to suppress parasites.
How many hours and days are you going to acclimate it.
Or are you even going to know and acclimate it in 45 minutes like you always do?

Rivers run into seas. Are there massive kills of things that swim and crawl into different salinity water? Then there are tides.

You are caught in a burning building a saved but have smoke inhalation. Do the EMTs slowly change the air back to normal so you don't get shocked or immediatly place you on oxygen.

I thought of this thread last night when I poured 8 cups of salt into the sump to correct my salinity.

I am starting to sound like Paul. Sorry.

lol, about sounding like Paul. True, I was just going with what I’ve heard over the years that it’s worse to increase salinity quickly than it is to decrease it quickly.

I would call quickly something like 10 minutes. I have never had a problem doing it in 45 minutes. For the system I did it over 4 hours after my last flood event.
Disclaimer
throwing 8 cups in the sump only raises my system 0.001. It goes into a 100 gallon vat that dumps into a bigger one and both have large wave makers stirring them so dirt doesn't settle in them.
I do it a couple of times a week.
Sea animals seem very evolved to deal with changes in salinity and not die. Thats why you can FW dip them and not kill them. IMHO the same is not true for other osmotic agents only in aquariums like nitrates. Fish have not evolved to deal with those. It is actually quite bizarre to me some of the concoctions people dip animals in.

Having a hurricane or typhoon over a reef with torrential rain does not cause a mass extinction event.

Ugh George! I miss my tank but then I read things like this and remember why I literally threw in the towel.
