Small, daily water changes
Old 01-02-2013, 03:26 PM   #21
 
I am in agreement that if a biological balance can be acheived that water does not have to be changed as much. Right now for some reason, in a planted tank (3.5 weeks old) I'm showing nitrates between 10 and 20 ppm and I'd rather show <5 ppm.

Because of this I've been doing small water changes daily since observing the nitrates. I'm heating water to 21 in the tub (to avoid using hot water tank) so the largest change I've done is 18% today (12% the day before, 10%, 10%).

For some odd reason the nitrate readings persist. I do hate reagant tests where the colour judgement can be subjective. I did check the tap water at trace so that does not appear to be the issue. In soil, it takes some time for nutrient cycling microorganisms (protozoa & nematodes) to establish for plants to uptake all nutrients and I suspect that may be what is occurring here but I'm unfamiliar with the waterplant microbial nutrient loop.

I'm tempted to use a product to lock up the nitrates. Prime has been mentioned but it also treats other things like chloramines which I do not need. Seachem recommends Purigen for this. Any thoughts...experience?

I chose not to use the hot water tank water either, over concerns of adding unnecessary calcium to the tank. Are there other reasons that it should be avoided?

I have since changed my mind as I am just going to cut in some RO water anyway so the added calcium at that point will be negligible. It would just make preheating the water a lot easier.

I would not use any chemicals expecially to lower nitrates.

An initial nitrate value is part of a planted tank cycle as the plants are consuming ammonia for nitrogen.

Just let things be and nitrates will drop down once the aerobic bacteria build up and consume the ammonia.

Copper. From the hot water heater is another conceern. I always use straight tap water from a commonly use cold water faucet. And let the water run 30 seconds to a minute before collecting. (I also just top off). That way I reduce copper and other things that result for long hot water contact with the water heater tank.

If my readings are Am-0 Nitri- 0 and Nitra- never been above 3,(closer to 1(its a 1-5 scale)) even with a longer gap between water changes etc - over xmas - would i class this as having a balance? If thats the case, why do i change the water?

Ok, so i change it to lower nitrates......if they never rose- ive obviously not tested this over a long term basis - i basically wouldnt need to change it for that.

What about other minerals etc etc that get used up in the tank? Doesnt a water change supplement these, how do you then deal with this - if we are going to go wildly of topic, i'd be happy to take this to PM. I dont want to ruin the thread.
On the reason for water changes, I ask that you read my article on the subject as I see no need to repeat two pages here when it is all there. Here is the link:
http://www.tropicalfishkeeping.com/f...hanges-117205/

As you will see, water changes are essential in most fish tanks. There may be a few exceptions. But these are not the tanks most of us have.

Do you see any value in inoculating with Seachem Stability, supposedly aerobic and facultative anaerobic bacterial spores?

There should be little concern over using some hot water from a hot water tank as the amount of calcium and lime is so very small. It is always a good idea to let water run awhile before using for the aquarium to flush out water that has set in the pipes (copper, lead, etc)

There are no chemicals that remove nitrates. Prime binds nitrates which merely detoxifies them for 24-48 hours.

This statement is incorrect. aerobic nitrosomonas bacteria oxidizes ammonia into nitrites and aerobic nitrosprira bacteria oxidize nitrites into nitrates....as a result, nitrates increase. There are species of anaerobic bacteria that will oxidize nitrates into nitrogen gas. However, these bacteria can only survive in an environment with little/no oxygen which is extremely difficult to create in a fish aquarium.

The notion that there is no need for routine water changes is equally incorrect. Oh with a lot of plants and very little stock, one might 'get away' with few if any water changes, but it's risky for the vast majority of aquariums. As Byron (and countless experts) point out, all aquariums with stock benefit from the periodic removal of polluted water, replacing it with fresh water...just as nature renews fresh water with rain.

And to the OP, your water isn't so bad.... I have 60-80ppm nitrates in my well water from a 95 acre farmers field across the road!!!

Your plan to minimize water changes is good. Use lots of plants, even floating to reduce tank nitrates. Keeping the tank and filter clean and not over feeding really helps.
Seachem Purigen can be used to adsorb dissolved organics, before they become part of the nitrogen cycle. Purigen can be regenerated several times in a 50/50 water/bleach mix.
Products like Fluval Lab Series Nitrate Remover (FNR) and API's Nitra-Zorb are synthetic resins that effectively adsorb nitrates. They are regenerated in a salt water solution.

Keep us posted.

Off into town today, so I'll go to my LFD and see what he has in the line of Nitrate absorbing filter media. I was always under the impression the nitrate removers were some some of liquid chemical you added to the water *doh* and I hate adding chemicals.

I know I'm also probably guilty of overfeeding so I'll cut back and miss out feeding altogether one day a week. I will get these nitrates down *stamps foot*

Thanks for everyone's help, even that which went over my head.

This is a great forum and very friendly. I ventured into one or two fish forums before I settled here and found some of them a bit erm ... over critical ...not always helpful when you are genuinely trying to create the best environment for your fish.

I'll let you know how it goes
