Does This Tank Need To Be Cleaned?

[guruboy]

Just had this LP72 steel tank tumbled and then hydro tested. It passed and came back like this (see pictures).

Does the bottom of the tank need to be cleaned more?

yes, bottom needs to be brushed out. tumbling may not help, but you need to use a brush on the bottom

Shoot. The bottom was the reason I had it tumbled. Guess I wasted my money there.

We have hydro shop here that does internal shot blasting of tanks. They get less than 20 bucks to do it and it does a better job than tumbling. This may be worth looking around for.

if it looks like that after tumbling, you need to get your money back... When you get it back from tumbling, there should be nothing left on the walls, or the bottom. It looks like they "tumbled" it, but didn't do it properly.... sorry

It needs more work for me to be satisfied with it.

Look on the bright side it looks like they almost finished the sides of the tank.

If thats what they call a "Tumble"...and / or "clean"...I shudder to think what other maintenance and/or dive practices they engage in.
Get your money back...and warn all your dive buddys.

oh, just reread the OP. The tank shouldn't have looked like that coming out of the tumble session and unless the hydro shop botched the job and let it sit with water in it for a few days, the bottom shouldn't look like that... You need a new dive shop buddy because this one clearly doesn't know what they're doing

1. get a refund on the tumbling
2. find a shop that can use an extension brush on the bottom (quicker than tumbling)
3. if you have it tumbled again - ask to check it before paying for it
4. relax - the walls look real good
