Most of your advice is sound, but... I think people put too much stock in the whole pH shock thing. I've had a lot of mistakes along the way and tbh I've moved 3x and had to break down and put my tanks back up. Logistics in moving large tanks beING what they are, Ive always ended up having to replace 50- 75% of the water. I haven't lost a fish yet and this last one, it was 30 degrees out and snowing. Generally speaking, you should change some of your goldfish’s tank water once per week.

If you have white cloudy fish tank water or gray cloudy water in your fish tank and you have just set it up, it could be the dust from the gravel or sand. Be sure to thoroughly rinse your substrate before adding it to your aquarium. This can be difficult to do with sand but the dust particles should settle in a day or two.Usually the result of an algae bloom. Read up on how to . The green cloudy aquarium water will not harm your fish but it is not the most pleasant thing to look at. This happens because of the amount of nutrients and the amount of light entering the aquarium. Your tank water is nutrient rich, which may mean that you're feeding too much, your tank may be overstocked or you're not doing enough water changes or a combination of all the above. The main problems are usually high nitrate and phosphate levels. If you have a saltwater aquarium consider using a and . Avoid placing your aquarium where it could receive direct sunlight. Direct sunlight will add fuel to the fire so to speak and direct sunlight will cause temperature fluctations as well.An aquarium with water so dark most plants cannot thrive and fish are practically invisible may sound senseless to some, but there can be many reasons to invest in this type of tank.The easiest and most obvious - and usually the cheapest - is to usetap water. Tap water is available to almost anyone keeping anaquarium, and is almost always going to be fine for yourfish. However, you do need to be aware that if your tap water is froma municipal water supply, or if you have a holding tank for your watersupply, you probably have chlorinated water, and you will need to usea to make the water safe for your aquarium, depending onwhich compound is used in your water system.To correct this problem, perform 25 percent water changes daily, rinse out or replace the filter media to reduce the amount of nitrates, feed your fish a little less and leave your off for a few days or until the water clears up. If you do practice good aquarium maintenance and still have algae problems, look into testing your tap water. You may be introducing nitrates and possibly phosphates into your tank via the water changes and not even know it. Also look into keeping live aquarium plants which will compete with the algae for available nutrients.Bottled water is another choice people consider. I would recommendagainst bottled water unless you KNOW your tap water isunsafe. Bottled water is often not regulated or tested, so the waterparameters are unknown. Also, bottled water often has vitamins,flavors, preservatives, colors, or other additives added to make thewater more appealing. These can be devastating to your fish tank.
