Hello everyone!
I just acquired a new tank, a nasty looking Craigslist special. When I brought it home my lovely wife was totally horrified by the looks of it!>:)
Hence the name of this thread!


Check out the photos below. It was used as a saltwater tank. I am planning to convert it to freshwater planted tank. I always wanted a tank with a sump setup, so this is like the ultra poor man's cheap Ferrari for me! Excited!! :grin2:

But, I gotta clean it first! Any cleaning tips for that nasty crusted algae on the weir?


Here is what it looked like, in the Craigslist listing:






By the way, it is a 75 gallon, not 90 gallon as the seller says in the CL listing.





Horrifying, right? Only a fool like me would go get it! >:)


Anyway, after bringing it home, it is sitting on the deck. Took these photos as I started to spray some water on it...





It has a "proper" Durso overflow!



Came with a sump



Protein skimmer, not sure if it is usable/working though. It may be useful later on......when I want to get Discus fish.




Came with a couple of pumps, I tried plugging them in, both seem to be dead


More soon!

Congrats on the score! You don't need to worry about coraline algae containing palytoxins. That's a concern for when fragging the live animals, but I've never heard of any surviving dry. Mostly what you are up against is calcium based algae. It's a real shame the owner of this didn't at least clean the tank and give it a good wipe down when he broke it down. As for cleaning, it can be a beast getting caked on coraline off of glass. I generally use full strength vinegar soaked in a towel for an hour or two at a time. Just turn the side down you are working on and let it soak, it will eventually break up and release its grip. You want to be very careful not to scrub too hard because the shards of this stuff can scratch things up if you aren't careful. Muriatic acid might be needed if vinegar can't cut it.

I'd clean up the skimmer and put it on CL and recoup some of your spending. They aren't effective in freshwater, it's just too thin to get much of a skimmate.

if you put the vinegar into a spray bottle you can 'spray fix' kitchen towel sheets onto the vertical glass, (if you can steal an electric steamer from the kitchen while the wife is out too you can put that inside and cover the tank then power it up occasionally to humidify the air to delay the vinegar soaked sheets drying out )

Update

Thanks for the tips guys! I appreciate it!


Here is the latest status:
This morning I sprayed everything down with a garden hose. I was surprised that most of the gunk on the glass came off easily. Then I scrubbed it with a brush and now this is what it looks like:


Tank:




Sump:







Why is the weir double walled?




The problem child:



The skimmer...I think it is missing parts.




The overflow pipes setup

Vinegar treatment:

I soaked a towel in vinegar and wrapped it around the weir. So far, it doesn't look like it's going to free up or dissolve any of that buildup from the weir.
Maybe I should wrap the tank with a tarp and leave it overnight.



Yes vinegar worked well for the glass. I brushed neat vinegar, with a little bit of scrubbing most of the deposits came off. Now very little white spots are still left on glass ...



I brushed neat vinegar on the inside of the skimmer, then soaked the skimmer in a dilute solution. Hoping to get it reasonably clean.

Coming along nicely! Skimmer seems to be missing the pump, pump attachment and lid. Might be worth a message to the person you got the tank from to see if they have it still. Near worthless without, seeing as sourcing those would cost as much as a new mid-range skimmer. If that was an H&S or Bubble King, I would say otherwise. Let the vinegar sit for a long time, it never really stops working unless it dries or is spent. It will never eat through the glass, so even if it's 48 hours, it beats scrubbing it off and potentially scratching glass.

I have the pump for the skimmer, it's shown in the bucket of water in the first post l. I plugged it in, doesn't work. It does have the air sucking mechanism attached to it.

Lid? Hmmmm, can you please check the photos of the skimmer in the second post above. Does it seem like the lid is there?

Shouldn't it have anything inside it? Like a mechanism or something?

This skimmer doesn't seem to have any marking on it. I was expecting a make and model somewhere on it.


Also, I wonder if vinegar will affect the tank's silicone.

Ah, I see in the earlier photo that lid is there, sorry. From the side it looked open. There's not much else to a protein skimmer, they're pretty simple devices. I'd take the impeller out and clean it, hopefully fires back up. Sedra appears to still be making these if you do have to source anything. Does this look like your model? https://premiumaquatics.com/products/asm-g2-insump-protein-skimmer-sedra-pump-open-box-return.html

Bing!

Thank for the info! Yes, you are spot on :) :grin2: Mine looks exactly like the one you linked.

So it is the ASM G-3 model with the Sedra KSP-5000 pump.


I will check it out further, yesterday I took off the pump's "cap" to check out the impeller. I noticed a couple of those needles were broken and the impeller was jammed. I plugged it in anyway, hoping the motor would at least hum...but it did not seem to hum. Now that I know that impeller is replaceable, I will try to pull the impeller out today and try firing up with pump again.



BTW, when I plugged it in, I got a 110 volts shock! Had wet hands, my bad! First time I got a 110 volts shock......so much better than a 220 volts shock that I have got many, many times! :surprise::nerd:


PS: Now I know that the outlet on the deck is not GFCI protected, JUNK!

Yes, I am crazy! :grin2: and like my lovely wife loves to say, too cheap!
Money saved? I like to think so...it was 100 bucks for everything.



I was planning to drill my existing 60 gallon for an overflow. Just the overflow box I wanted is around 130 dollars. Sump, pump, plumbing etc would have costed much more...so I think this is a better bet. Plus I like this tank's dimensions and aspect ratio better.


PS: The cleaning (so far) was surprisingly easy. The tedious part is taking off the crusted coraline algae from the black plastic weir. :frown2:



Wow what a cleaning job you signed up for - good work though and nice money saved I'm sure!

The double wall on overflow box is a high/low flow balanced design so water is pulled into all the slots on outer wall equally.

When you get tank clean set on garage floor or outside on a level surface, shim if needed and leak test for few days to make sure all the seems are solid and don’t burst. You don’t want that happening in your house.

Thanks for this info on the overflow box, Dave. It's a curious design. I used to think that weirs are supposed to skim water from the surface of the tank, so that it stays clean of the buildup we sometimes see in our tanks.

Also I read that co2 setups benefit from water skimmers, I forgot what their point was though.

And yes, I do plan to set this tank up on it's stand in the garage for a few days. Wanna make 100% it doesn't leak. The seller insisted that it doesn't leak, but when I went to pick it up, I noticed the carpet under it was wet. I pointed that out to them, but didn't get a satisfactory answer.

Maybe the two bulkhead fittings leak. I do plan to change those washers/seals with brand new ones.

When you get to water testing with pump float a little flake food in front of those lower slots and you’ll see it suck it and upswell in the slot sweep it up and over that inner wall rim.

We were building tanks with those type of overflows late 90’s early 2K era so they’ve been around for a while.

You basically need enough pump to fill all the slots with decent water flow. If you want to go with lower output pump it wouldn’t be hard to modify that inner wall but still get good surface extraction.

Clean tank!

All right folks! I got the tank and the overflow super clean. The towel soaked in vinegar got almost all of the overflow clean. It dissolved almost everything there into a toothpaste type thingy.


So I got excited and went out and bought some Muriatic acid for the internal baffle of the overflow...it still had tons of deposits. But the acid did it :grin2: Man it fizzes and releases the bond almost immediately. Now the overflow's inside is squeaky clean!









I have set it up in the garage to check for leaks. Check out the pics:


Filling it:



I cannot get rid of these smudges in the glass, presumably made by the wavemakers



and




Overflow looks pretty big after filling it with water

Bummer!

Uh! oh! Bad news...

I discovered some pretty obvious scratches. Looks like someone tried hard to take off something. Too bad the glass is scratched right in the middle of the viewing area. These were not obvious when I was cleaning the tank. Only after I filled water in it they became apparent. They are pretty visible when the tank is lighted up. I taped the background back, temporarily to see if I can live with the scratches...I guess I have no choice at this point :crying: They are hard to photograph....but pretty visible in person.


I'm pretty disappointed! :frown2::crying:

Check it out...





I do not think scratches on glass can be repaired or reduced, right?
