Campden tablets

[GaryE]

I used to brew beer, and in looking at my old stock, I noticed I have campden tablets for food grade dechlorination. They are still good, and in a few weeks, I am going to be restarting a rather large fishroom, dechlorinating a lot of water. I'll be dealing with chlorine, and not chloramines.
Has anyone here used crushed up campden tablets to remove chlorine? They aren't indicated for aquarium use, because that would be a pretty obscure application given how well they sell for beer making.

I just did a quick Dr googly on the interweb thingy and probably would not use it for aquarium purposes. It contains sodium or potassium metabisulfite and probably isn't wanted in a fish tank.

Can you use Prime for Zymurgy? I'm not sure I ever de-chlorinated, but I never advanced past the kit stage. With the current prices for beer, I may get back into the hobby .

Prime is NOT suggested for beer making as it has some ingredient secrecy going, and that makes it dangerous for anything we'd consume. I hate buying products with secret ingredients - I'm now on the lookout for good old sodium thiosulfate.
I rarely use any dechlorinator here, if I am going with 25% water changes (I have no chloramines in my water and chlorine mostly gases off). But I am going to be filling a lot of tanks from scratch, probably around 1500 gallons total.

If you only have chlorine in your tap water, just fill the tanks and let them aerate for a couple of days. that will get rid of the chlorine.

I use API Tap Water Conditioner, which does state the ingredients - sodium thiosulphate (for chlorine) and tetra sodium EDTA (to bind metals). No aloe vera or other additive to 'stimulate the slime coat' and no secret ingredients.

 

[GaryE]

If I'm going to add chemicals to my water, I want to know which ones, and I want them to go in clean.
Aloe is a gimmick in water, and most things that stimulate slime coat production (like salt) are irritants. The fish secrete slime to protect themselves from potential burning sensations.

Hmm. I may be stuck with a seachem product. I have an immune suppressed family member, and given the pandemic where I am, I'm not going to be wandering through aquarium stores anytime soon. Priorities...
I don't want to online order anything liquid, as it could well freeze in transit here, at this time of year. I see "Safe" as a dry product. All I need is thiosulfate, but it's seemingly hard to come by.

All I need is thiosulfate, but it's seemingly hard to come by.

Wardley Tristart contains sodium thiosulphate and should be available in the USA. You might be able to find a shop that will send you a few bottles.

Alternatively, get a couple of big buckets, fill them with tap water, and aerate them for 24 - 48 hours.
