LR curing question - sitting in water 7 years

[duijver]

Hi Everyone,

So, I took a fairly long hiatus after two tank crashes due to extended power outages and I have really been fighting the itch to restart since Covid started.

Now, I still have a lot of my equipment except for the main tank... So, I just picked up a Fluval EVO XII (13.5 G AIO) as a quick way back in.

My question is, how do I deal with my old LR that has been sitting in a water mixture for about 7 years. Should I just add it to the tank after a few SW rinses? More details below.


Shortly after (or maybe before) my breakdown I bathed some of my LR (30-50lbs of a mixed bag of Fiji, Pukani, Tonga, others) with either Muriatic acid or H2O2 35% followed by bleach. I am pretty sure that I did a Vinegar bath as well somewhere in-between or maybe instead of Bleach. Too long to remember.

Then I let it sit with lights off in a heated brute with salt water (I am assuming salt and with high salinity, but I can check that later I guess) with flow for a couple of weeks.

Then the Brute (maybe it was pre-Sandy rock I was cooking) sat in my garage until today. I opened it up and there is a light film on the top of the water, but otherwise the water is crystal clear and I still see quite a fair amount of Coralline algae on the rocks.

I still have LiveSand and before I opened the brute I was thinking about seeding the rock from the ocean.

I appreciate your time and guidance!

I snapped a quick photo of one of the rocks in the brute. I am surprised that some algae and the Coraline (maybe dead but not bleached?) survived for 7-8 years without lights, proper heat, or a WC.

It seems like this forum will not let me post embedded images, so maybe this will work: https://ibb.co/dKw6VZd

IDK...if its been sitting that long and it has coraline algae growing maybe its worth a try to put it in a tank with circulation good water and see what happens. I mean you really got nothing to loose.

I definitely wouldnt seed it from the ocean. While that sounds like a good idea on the surface, you might end up "seeding" things into your tank you dont want in there. Its a lot easier to keep bad things out of your new tank than it is to get rid of them once you got them in there!

Get some Fluconazole this great for fighting hair algae and bryoiss.

Looks surprising good. I would not over treat it. I would put in and see what happens.
