Assuming a healthy aquarium, how often do you use this?

I've only had to use this product when I had a problem with setting up a new tank. I just use their conditioner once a month after the tank is well established.

It personally identifiable use it when it do waters changes. I also use it when it when there is a slight ammonia spike in between waters changes.

You use 5ml for every 10 gallons of water upon the setup and use it with every water change but only use it in the water you are changing for instance if you take out 10 gallons of water you add 5ml of it to the 10 clean gallons that you are putting in that's all you need and this bottle will last you quite a while if you have only one or two medium sized tanks. This is the proper way to use it as per the instructions that are on the bottle and I called them to be sure.

From what I've read and what I've experienced,the fertilization/nutritional aspect of the substrates depletes with time as your plants use it. How long it takes depends on how dense your aquarium is planted. My lightly planted tank last about 6 months. Just be careful with it because can change your water parameters if you get a bad batch. If you see any white specs or rocks, Do Not Use it. See my review for more info.

The instructions say that once you have a clean tank, you need to use it "periodically" to keep your tank clean. I presume the frequency you use it depends on your water (e.g., well water, city water, conditioned water, etc.). The type of water you have going into your tank may make a considerable difference in how often you need to use it. I have a water softener, so the water going into my tank is softened and I need to use the toilet tank cleaner infrequently. Someone with hard water going into their tank will likely need to use it much more frequently. Just check your tank once in a while and you'll know when it's time to use it again. Hope that answers your question. The instructions say that once you have a clean tank, you need to use it "periodically" to keep your tank clean.

I've had it for only a month but it's a hard wintertime and air indoors is very dry and full tank is good for no more than 20 hours. I cleaned the filter after 3 weeks but I will do it every 2 to be safe with my hard water.

I use what has worked for over 50 years - change about 1/4 to 1/3 the water every month, vacuuming the gravel to remove waste when I do so, and change the filters at that time. I've got clean water conditions and minimal losses to anything other than old age. Have even had spawning in 2 tanks this summer.

I have one beta fish, and rocks at the bottom of the aquarium. I tend to clean the bowl weekly as it gets a bit cloudy. But that said, I also tend to overfeed my fish a bit :)

Depending on your biomass I think about once a month. I usually trade off between rinsing the sponges and replacing the carbon (PS to save money buy cartons on carbon and refillable bags). IF you miss a cleaning nothing too dramatic happens but it's good practice.

I usually go 18-24 months under normal use (<5 gallons/day). They typically will advise a year or less so you buy more. Never have a changed one that is visibly dirty. I also bought an inexpensive total dissolved solids (TDS) meter to monitor monthly.

I would clean and do a full water change once a week. The filters are easy to find on amazon for cheap too and should be changed out every 6 weeks or so. Other than full water change and just wiping down with a paper towel, it's a pretty low maintenance tank.

I have run at least a dozen tests and I still have plenty of fluid left. Its a great value. I would say easily 6 months to a year of tests. I usually test water quality about twice a month now. Every other water change since I don't see any problems in my aquarium.

I also have a 100 gallon tank and I put in 100ml of purigen when i clean my filter out which is usually about every 3 months

If you're concerned about bacteria levels in serious sized tanks, please consult with an aquarium store or service and not a pet store chain. Just asking means you know more than I. Product web site and or Internet may have your answer also. For the device in question, it's often slow to appear effective. I would use a larger unit for 55g tank and expect to wait 24 hours per 10 gallons for results. But the results are awesome. I use one in every tank. Crystal clear effect is no exaggeration.

I wash it out once per month, mainly because I over feed my beta. You do need a sponge filter on the intake, or you fish will be trapped by the suction. Also I only run the filter a few hours each day so the fish can rest.

I change it once a month. I have 3 cats and 1 dog. Fill up the tank every other day.

I use it when I do a 10 % weekly water change. And on initial tank start up, waiting a few days before adding fish.

I just change it regularly every 3 months. It also depends on how many fish you have in your tank. I think you can use the aquarium salt to recharge the granules.

it actually depends on your useage, water quality, and seasonal factors. to be safe, every 6 months to a year will do. -J
