Hello; First a bit of background. I needed to take down all the tanks in my fish room. I wanted to take up the carpet, both for my tanks and to have a wood burner in the room. I put down commercial vinyl tiles.

I set up spare tanks here and there to house the fish and plants. I decided to try to clean and disinfect my tanks as they are set back up in the fishroom. I have read about using chlorine to do this. After rinsing all the gravel I let it soak in a clorox solution for a time. I also test filled one tank and put a bit of clorox in it while it had only water. I allowed it to run empty for about a week with a HOB going. I put in some gravel and allowed it to run with the HBO and some bubblers for a couple of days.

Here is what I have learned so far. Even with the gravel having been rinsed off and the tank running for some time there was still enough clorox remaining to promptly kill a few snails I tossed in. A few live plants I put in at the same time, however are looking fine so far after three days. That I was suspicious is why I only tried a few snails (ramshorn snails).

The only water conditioner I could find locally is Tetra Aquasafe. I put some in today and a couple of hours later added a few snails. These snails are doing fine. No point in getting in a hurry to add more plants and especially not any fish.

I had not ever used clorox to disinfect anything about a tank before so this is a learning experience. I have learned that the gravel will need more of a rinse and/or a soak in a solution of safe/prime. The next time I make the 60+ mile drive to Knoxville I will try to get a container of safe. Am I correct in thinking that SAFE is the powder form and that it will have a long shelf life?

As the first tank has only water, gravel, some snails and a few plants what might be a good next step? I could drain most of the water out of the tank and then refill it? I could trust that the Tetra Aquasafe has done the job and the tank is ready for cycling?

One thing that may come out of this is a new, to me anyway, appreciation of live plants ability to handle a clorox solution that will kill snails. If the palnts do survive, then a way to kill parasites and pathogens might be in a clorox solution dip for a day or so.
 
That is really interesting. I'd love to know this it turns out. :) I clean everything in a bleach and vinegar solution, one part bleach to nine parts vinagar. Only problem I've found is that the more 'sensitive' plants can only handle a 60 second dip, but most are fine in a 3-5 minute dip. Then I rinse them under the tap and place them to soak in a bucket of water overdosed with prime, for one hour for every minute they are in the bleach.

Your way seems like it may be an easier way to do things, I wouldn't have to read countless bottles and smell countless fumes to ensure that I'm buying straight unscented bleach. And it gives the plants more time exposed to the chemical which means more resistant pests are more likely to cark it. :D

First; What is a cark?

Next; I really do not have an accurate estimate of the strength of the clorozx solutiion.

I will post more as time goes on. I will name the type plants if they survive.

Lol if something/someone 'carks it' it means they've passed on, rolled over, moved to the next world etc. :)
 
Chlorine and Chlorox are not the same thing. Chlorox is sodium hypochlorite. Chlorine naturally dissipates in water over a period of around 24 hours.

Sodium hypochlorite, on the other hand (in a 5% water solution) can take months to dissipate.

You will want to use a dechlorinator when you are trying to neutralize or get rid of the chlorox.

Tetra Aquasafe is a dechlorinator, so that's why things cleared up.

Hello; Thanks for the update. As I had not used clorox to sanitize aquarium stuff before, the step of adding a dechlorinator was not a part of my experience. One of the reasons I only took a chance with a few snails.

My plan for the future is to have some water treatment on hand. Am I corrrect in thinking SAFE is a long term shelf life stable product?

I assume you mean Seachem Safe. According to Seachem the powdered form is "good for the life of your aquarium", so effectively it will not degrade significantly under normal use. You do have to keep it tightly closed when not in use of course.

Hello; It has been over two weeks now. The excess chlorox killed the dwarf Sagittaria plants but not the Cryptocoryne and java fern plants. The crypts have not died yet but developed a shine on their leaves compared to their normal look. I have not yet spotted any new growth from the affected plants so it may be too early to say.

I think some of the ramshorn snails may have survived the treatment. It is hard to be sure as I put some more snails in the tank after adding the de-chlor water treatment. I base this on the observation of the bodies being gone from where they were laying and seeing more snails moving around than there should have been later.

This may be a common thing to those who use the de-chlor chemical water treatments. I noted what I think may be a preipitate in the last few water changes. Could this be from the chemical binding stuff in the water?
