So it's been a while since I updated on the tank shenanigans with the 38 gallon.
After doing a 90% water change down to the substrate I refilled it completely with new salt water, ran it for a month and tried a (what I assume to have been well acclimated) molly as a guinea pig to see if there are any more issues with the tank being able to actually keep fish. The Molly didn't make it to the next day. That could have been because I did too fast of an acclimation and it wasn't ready to go in the saltwater or because of any residue in the tank.
Another 3 weeks I added a damsel fish which lasted longer, about 5 days, but ultimately died as well.
Because I'd like to keep more than snails and corals in the sink I am going to be tearing it down completely, removing the substrate the filter the live rocks everything.
I will then refill the tank with fresh water and some bleach and allow it to run for a day or so in the hopes of cleaning the filter out as well and then do a 100% water change add a bunch of safe to the water and allow that to run for a couple days before I do a 100% water change again and also I had a bunch of safe to the water and run it for another couple days.
Once I'm sure that I have worked out all the bleach in the system then I will go ahead and clean the tank and hopefully reset it.
I have moved all my corals and two of my live rocks that have mushroom corals on it into my 13 gallon. I will not be keeping any of the other live rocks but replacing them with a mixture of live and regular rocks. I also have a reverse flow under gravel filter that I will not be replacing. I purchased new hoses and new filter media for the Fluval 307 that I have set up on the tank. Also hoping that the little bit of bleach in the water will help decontaminate my current makers as I'm not sure how much plastic has absorbed any of the scorpion fishes toxins. I've never had a saltwater fish tank that had a scorpion fish dying it so I'm not sure what the issue could be but I'm trying to cover all my bases.
It's a bit overwhelming but my plan of attack is:
- Remove the remainder of live rocks and drain the tank as much as I can.
- Remove the substrate going through it to pull out any snails that I can find and staying away from the bristle worms.
- Pull out the undergravel filter and clean the bottom of the tank as best I can.
- Remove all the media from the filter and empty it of all salt water.
- Make a dilution of bleach water and refill the tank, leaving the current makers in the tank to aid in water movement as well as possibly cleaning any toxins or residues from the current makers themselves.
- An hour or two later try to remove as much of the bleach water as I can, refilling the tank more fresh water and a bunch of Safe. Let the tank run for a few hours at least.
- Rinse and repeat, but let the tank run for a day to ensure that there are no bleach residues in the tank.
- Empty the tank and clean the glass of any algae and other residues.
- Clean out the filter, and redo the tubing system with the new tubes that I purchased.
- Rinse out 40 lb of dry sand (FUN).
- Reset up the tank with the sand, and set up the filter with the new tubes and filter media.
- At the new live rocks and other rocks and add a container of the turbo start bacteria starter.
- I think I'm going to leave the tank to run for a day or so before I introduce the corals back into the tank.
It's a bit overwhelming, and I got to purchase a couple things before I am able to actually set it up like the live and other rocks and the turbo start.
Anyone have any suggestions on the bleach ratio for 38 gallon? Not sure what kind of concentration I would need that would be safe running through the filter and going through the current makers.
The 38 right now.
