Fish Tank Maintenance Clearing Up Cloudy Water in Fish Tanks
OK, we can get our tank set up and then frequentlywhat happens is, seem to be doing everything right and then all of a sudden you wake upand you have cloudy water. No reason to panic. This is a frequent thing that happens andit really has to do with natural causes. What frequently causes cloudy water is or chemicalimbalances is that naturally occur. Remember we talked about that imbalance of bacteria,the negative bad kind of bacteria overcoming the beneficial bacteria that takes a whileto build up in a naturally occurring system such that it'll cause cloudy water. The otherthing that can happen is you can inadvertently overfeed fish and the water will not be ableto take on and naturally purify it as it will
later on when the aquarium's established.It'll cause a bloom and cloudiness. The other thing that can happen is if you have too muchlight, too much photosynthesis, too much biology going on here and it causes algae to bloomand you can get an effect like this. Not to panic, there are solutions to every aquariumsituation that comes up. The importance of the frequent water changes will really help.The other thing, instant answers in the form of products that will clear your water. Thisis our favorite one here. This is called Acurel, we love this product. Follow the directionson the bottle, it's very simple. This will not disturb the biological beneficial bacteriathat's occurs in your tank. They made it with
that in mind. Simply, OK three drops per gallon.So we're going to add, this is a larger tank here. We're just simply going to drop thedrops in and count. One, two, three, four, five. OK, this will take a while to take effectand in a couple hours we're going to come back here and this presently cloudy tank isgoing to be pretty much crystal clear. And then, it's your job to from then on continueto practice good aquarium maintenance procedures as far as not overfeeding, making sure thelights not on, doing your frequent water changes. And on we go to enjoy our clean, healthy,sparkling clear aquarium.
A Quick Fix for Dull Foggy Photos in Photoshop Add Instant Contrast and Pop to your photo
Hello, I'm Helen Bradley. Welcome to thistutorial tutorial. Today I'm going to show you a quick fix for a dull or muddylooking image. This is an image that lacks tonal range. It lacks contrastand we're going to give it a punch and we're going to do it quickly and easily. In this tutorial tutorial I'm going to showyou how you're going to fix an image that looks a bit like this.This image is what I would call muddy. It actually lacks tonal contrast. There noblacks in this image. We've got some light pixels around the sky area but there areno blacks. And the result is that the
image looks a bit foggy, a little muddy, a little lacking intonal range, lacking in contrast and the color is a little bit flat as well. And this is the fix that we can apply tothe image extremely quickly and Photoshop will actually tell us how to make the fix. It will tell uswhat's wrong with the image and how to fix it. So let's have a look and see how we'lldo this. To start off with, with the image openin Photoshop I'm going to choose
Window and then Layers because I want to seethis layer's palette. Now we're going to choose an adjustmentlayer. It's exactly the same as making anadjustment except this time it is editable, and we would like to get you startedusing adjustment layers because it gives you a little bit more power in Photoshop.So we're going to choose Layer, New Adjustment Layer. And the one that we're going to use iscalled levels. So let's just click on Levels and see what we get.
We get offered to add a newlayer so I'll click Ok to say yes. And then we get this dialogue here. Now this might look a little bitconfusing but it's actually Photoshop telling us what's wrong with the image andgiving us a chance to fix it. This is the pixels in the image. It's ahistogram. And what Photoshop has gone and done is it's hada look at every single pixel in the image, how light or dark it is, and it's counted up how many really darkones it has and how many middle
tone ones and how many light ones. And it's done that for all the255 tonal ranges in this image. So we gotfrom 0 to 255. And it's telling us how many pixels arein each of those ranges of tone. And this is black and this is white. Soyou see that we've got a few pixels very, very white and then a lot of pixelsin that sort of light white area which is of course all around in the sky.
But see here, this is the problem in thisimage. There are no blacks. There's nothing in this black area of thehistogram. And so levels is not only telling us that but it's also giving us achance to fix it. So what we can do is we can drag on thisslider here, the one under the chart. I want you to ignore these ones all the way at thebottom. It's these under the chart that you're interested in. And when you see the chart
