Cloudy Water, Old Setup?

    Hey guys!! I've had fish tanks since I was 7 I'm 25 now. So I pretty much know all the ins and outs of fish, equipment, water quality all that good stuff. I've ran into something I've never had a problem with before....I've had my fresh water 45gallon tank set up for months now (like 8) and everytime I do a water change the water gets this cloudy appearance for a LONG time. Like I'm talking it doesnt start to clear until it's time for the next water change. It's kinda like a cloudy white ish...not milky but like a slight cloudy. I've tried water clarifiers...I've changed my filter... I've done everything I could think of and it's just not going away...oh theres only 4 fish in there all about 2 inches so I know ita not overstocked.

    Have you tried.........Purigen? I don't know what your water quality problem is, maybe crappy tap water or something but if you have not tried Purigen then I would get that to clear up the water.

    The water in your tank might be cloudy due to dirt, sand, fish waste, particles, plant matter, and uneaten food floating around. Moreover, the particles might be way too small for your filter to catch. The stuff making your aquarium water cloudy can’t even be detected or stopped by the filter.

    Try the information here first (Make sure you have fine filter floss in your filter):


    Build a DIY Water Polisher here. I built this and it works great in large tanks:

    For smaller tanks, try this:

    Diy Micro Gravel Vacuum/water Polisher

    If all the above does not work… this will:

    Acruel F

    Start with 1 drop per gallon first, not the 2-4 drops recommended to start. Your water will get cloudy for about an hour or so and then start to clear. Make sure you have fine filter floss in your filter. If you need another/higher dose 24-48 hours later, fine. All Acruel F does is clump the free floating particles together so your filter can now pick this up. Guaranteed this works wonders.

    Keep your tank crystal clear? Chemi Pure Blue

    Green water? Get a UV Sterilizer with flow control (13 watt) and set it to the lowest flow rate so the water stays in contact with the light the longest. Will clear in about 7 days then remove it.

    I've never tried that. I'll have to give it a shot! Would I use this instead of carbon?

    Very informative!! Thanks so much!

    It really is your choice. I personally don't use any carbon because it's uses run out fairly quick and I replace it with polyfil. You can use both if you want, but I love Purigen for the water clearing properties and it controls Nitrates, Nitrites, and Ammonia.
