Water Tanks for Storing Water

[TW]

I'm thinking of buying a food grade 1000L tank for storing & aging water. I've found a couple of 2nd hand ones. One previously held sugar & water (guess that equals glucose) & the other previously held cooking oil. Both are to said to have been thoroughly cleaned, but I don't know by what method. If I find they have been cleaned with either soap or detergent, should I give them a miss?

Thanks for any advice on this.

What material are the tank made of mate?

should be ok, just give them a good wash when you get them and let them sun dry for a week.

Matt, looks like some sort of plastic. Here's a picture of it. The one pictured contained cooking oil & has been washed with detergent.

I'm going to look at it today & guy says it will take a submersible pump - but the opening doesn't look big enough to me. I might have to cut things a bit.

The guy selling the one that had sugar/water mix hasn't yet told me what he cleaned it with. The picture is same as this one though.

Noticed add didn't say "Food Grade" - thought it did (got confused - been looking at lots). Guessing if it contained cooking oil &/or water/sugar, then must be food grade??? I will check, though.

ILLUSN, you think it will be alright, even though washed with detergent? Unless I cut a big hole on the top, doesn't look like I can easily scrub inside. I can leave in the sun like you say, but will the sun get enough access to internal tank walls, without cutting big hole? I can cut the hole, if that'd be best.

A container of this size will make water change night heaps easier, but I don't want to risk my precious fish.

Any other comments would be great to hear. Cheers & thanks, Robyn.

I'd cut the top off it, makes installing pumps, heaters and cleaning easier for you, being clear after a few months its gonna get some algae clean up.

just give it a good wash with tap water, fill it up and add a 3-5x dose of prime, then drain and sun dry it should be fine.

how much is he selling it for ? i work for an agricultural chemical company and we can get them brand new "un used" and they sell for approx $350 + tax if it's dearer than that have a ring around ur local agricultural chemical companies and try get a second hand sulfuric acid IBC least that way u can rinse it out and have no detergent residues...

It's going to cost $130 all up.

i've got one of those myself - plenty of room to put heaters, pumps etc thru the opening.

Hi Gypsy3, was yours 2nd hand? If yes, how did you deal with the detergent issue & did you have any problems.

Thanks
