Help please

I have a 36g tank.

Today I inserted 10 live plants. I have adequate parameters. However, I was trying to be too clever and I hooked every plant up with 1/8 fishing sinkers. I don't live at the house with the fish tank and I have work all day tomorrow.

I've been researching the past few hours and found that lead sinkers are apparently problematic in fish tanks. I would have never thought this the case since so many sinkers are at the bottoms of streams and people attach sinkers all the time.

I have a few questions now.

#1. Can I leave the sinkers in there for a couple days or so?
#2. If I remove them from my plants, is my soil therefore forever contaminated?
#3. Would my fish be safe if I remove them from the plants in a reasonable time?

If anyone used lead sinkers and has had success/failures, please let me know.
Thanks

I don't think you'll have any issues with the sinkers:

A couple of the responses in that thread hit on the key areas: Lead doesn't break down very quickly if at all and your Ph would have to be low enough that your fish would die well before lead poisoning becomes an issue.

The new plant weights that stems come with are largely zinc. That's mostly a reaction to the effort to get lead out of consumer products at every level.

Never used em before but I think everything will be ok even if u left them in there for a
month. I doubt it will contaminate soil so fast.

Mine are definitely lead. They aren't plant weights. They are sinkers. Do you think it would be ok to keep them there until 01/24?

You won't have any problems if you keep them in there until 01/24/2050 unless your Ph is somehow well under 6 (think acid and metal here). But if that were the case, you wouldn't be worrying about lead contamination.

A lot of the crimp on weights actually went zinc. Seems people crimp them with their teeth and the Federalies didn't like that. Of course being the super avid fisherman I once was I never crimped them with my teeth. <<cough-cough>>

The zinc weights don't taste as good as the lead ones.

Dilution is the solution for the pollution.
