The Nanostream 6025 is 2500 liters, so should work. But...Yeah, the stupid clips... I've had good luck with Seios, they've been completely reliable for me, everyone I've heard having problems with them bought them locally. I don't think I've heard of anyone having problems with imported ones.

If I remember right they only get to around 7-8 inches, so yours will be pretty much full grown. I think their latin name is Mystus Gulio? OOoh, Planet catfish says they get to 16"

That'd be pretty hard to tell unless you can get the fish to sit still.

Nutrient in the water, not necessarily that you're adding. Do larger water changes, 20% is tiny. Very likely. I had a green water problem I couldn't get rid of even after doing 90% water changes every day for a week. So I rubber banded a big clump of filter wool around the cannister filter intake and then rinsed and squeezed out the dark green muck a couple times a day. In 2-3 days the water was perfectly clear and the green never came back.

Two hours for 30 liters? My RO was fed by a pump at about 50 PSI and it was producing about 30 liters per DAY. At 15 LPH I'd be running that into a big tank and supplying the whole house with it.

I've heard people use "Goldfish" to refer to any kind of pet fish. I wouldn't be surprised if these people aren't fishkeepers, noticed there's something swimming in their pond and went, "Baby goldfish!" Yeah, they're hard to tell from colorless guppies. Similar size, similar shape, given the difficulty getting a good look at fish in a bucket, bag, etc I'd say they're extremely easy to get confused.

If you do a google image search you can also go by the pictures. Indian glassfish is another common name, probably better to search on, I just did now and every single hit on the first page was relevant.

Woah! Nice looking goldfish. I wasn't sure they existed. :lol:

Ummm...You can't find any info anywhere except for glassfish? Have you bothered to look at a picture of these glassfish? Because...That's what the rest of the world calls glass angels.

I'm skeptical that is the case. Fish usually do not need to purge salt as much as they need to retain water that would move out of their cells into the water by osmosis. If the salinity drops that basically results in huge volumes of water going into their cells and bursting them if they can not get rid of that water. Do you feel healthier and happier if you're stuck in a room that's at 98°F? I'd like to see proof that a lower salinity than a fish is evolved to handle is less stressful for it.

That's irrelevant. You feed the tank with ammonia until, basically, it can support a huge bioload. Then difference between the real bioload and the capacity dies off harmlessly. But, if you're wanting an idea, one medium severum in 20 liters produces about 2ppm of ammonia(When I put one in a container to treat him overnight) that would be about 0.00004 liters or .04ml I've seen references to a droplet of water being approximately .05ml. So call one medium severum equal to a drop of ammonia per day. Or a small tetra approximately 1/10th.

Bloody women.

Probably kind of work, but not very effectively, most of your cold would just be bouncing off the water's surface. The very simplest, but not best, method would be simply clamp it against the glass.

Hard to tell without pictures focused on the fish. But I'm inclined to guesstimate that in the top pic, right hand fish is a male, left is too overexposed to get an idea of its coloring. Bottom pic looks like probably a male.

If you have a skimmer or not is irrelevant, it's a matter of the salinity that's best for the fish and from what I've seen the salinity should be about 1/3rd that for a juvenile.

Careful your pictures don't get censored for implied swearing.

Bruy some artificial sea salt and a refractometer or hydrometer, as I've said in your other thread. 1.018 looks to be a bit too high to start with.

You'll need to bruy some artificial sea salt and bruy a refractometer or hydrometer. That link has the approximate water conditions, PH of around 8, salinity of 1.005 when small, 1.010 medium, 1.020 full grown. Soo, you'll also want to bruy some coral or something to keep the PH up.

Where did you bruy it from? They usually end up being kept in freshwater until they die. Have a look here: http://www.aquatic-hobbyist.com/profiles/brackish/gsp.html

They're strictly marine, though may handle brackish. You need basically the same stuff for any other marine tank, plus a chiller because they're coldwater and usually only live a month or two in tropical temps.

Cooling a PC and cooling a fish tank are different. Almost all PC cooling setups are simply cooling towards ambient temperature. So a big radiator/heatsink and fans works fine. A fish tank in a case like we're discussing you're trying to cool below ambient. Pump the tank water through a radiator in that case and it would heat the water faster. That would probably work well for cooling the hot side of the peltiers. Maybe 5 of these onesshould be able to get you about 200 watts cooling for some 400 watts of power usage with a near perfect heatsink. But then you have to dissipate 600 watts total with your heatsink. Something like this one is pretty big, at 10 inches long. It's spec'd at .3°c per watt dissipated. Ideally with good fans on it it should only heat up to about 210°C to dissipate that much heat. You'd probably want something that would be able to dissipate the heat without getting any hotter than about 80°c.

Anyone with a 12v power supply and a soldering iron could make something up. At the moment I have one connected to a small electric motor so you can put an icecube on it and it will generate power to spin a fan.

Definitely sounds overstocked, and you wouldn't a full grown cichlid in there, any SA cichlid will grow too big and then eat your tetras.

I've wondered how well a handful of peltiers would work. Probably put them on a big water block with lots of channels to pump the tank water through then a really big heatsink with fans on the hot side. Wouldn't be as electricity efficient at cooling as a proper chiller, but you could just flip a couple wires and turn it into a heater which it should do really well and probably at higher efficiency than a normal resistive heater.

How does anyone survive on 10mb? Glad I'm not on that plan, my bill this month so far would be $37,200.
