Chucks Calculator Question

I read from Rex Griggs' site that Nitrate should be about 10 to 20 ppm, but Chuck calculator says 5 ppm is the target.
So what should the target be?

Thanks

Always trust the Grumpy guy. Chuck's calculator has several figures in it that are not in line with current thinking.

I'm right.

I thought so, but had to ask anyway.
Hey, Do you like the Fertilator?
Thanks again

hey it's free- what's not to like :-)

Some folks will keep the nitrate leaner to enhance red coloration in their plants, but it is a fine line and best for advanced growers since it is easy to get algae problems if you let it go too low.

Just follow what Rex says the Grumpy Guy knows best!

My Nitrates are always high anyway. Usually around 20.

My nitrates are always zero. Will flourish nitrogen help that? And how much should I use? that calculator thing didnt help me at all. guess math is not my bag.
tank has been up 2 weeks with the plants. entire tank been up 5 months.

all stats in my signature.

Seachem Nitrogen will help. But it will get expensive quickly on a tank that size. Head over to www.gregwatson.com and order some bulk dry nutrients.

Wow that's quite a bioload! You should have some Nitrates unless you are doing water changes very frequently I would think. Perhaps a high plant biomass and high light tank with Co2 would cause Nitrates down to 0 also though. Yeah definately want to get Nitrates in the water or else the plants will die and algae will grow.

Rex has a good webpage if you have questions about dosing.

This is very difficult all the while Ive been thinking nitrates are a bad thing only good for showing signs of cycle.

I also have 0 or very little nitrates. I have a pretty large bio-load also.

This is going to be a tough thing to break ADDING nitrates into to the tank OMG.

I think you have confused nitrites and nitrates. Note the different spelling. Now go to www.wikipedia.org and look them up.

Take the time to read my Guide.

Fish-only people tend to think nitrates in the water are a big no no. I used to use nitrate levels to figure out when to do water changes on my goldies. Haha, how things have changed...

Also keep in mind that you are adding inorganic Nitrate to the water column which is relatively harmless. If I recall correctly one very repected hobbiest that is on here from time to time did some tests with Amano shrimps (which are way more sensitve than fish are to water quality). He found that shrimp did not die until the nitrates got to 100ppm. Thats a lot of KNO3!

In general though there are some things that we can get away with in a planted tank that fish only folks cannot and when these things are apparent it makes one wonder why they kept fish only tanks for so long when a planted tank is actually more beneficial to the fish and nicer to look at anyways. I cannot say how many times my fish have spawned and reproduced in my planted tanks no to mention the general color and display of natural behavior they exhibit. This has never happened in my prior 10 years of experience as a fish only hobbiest (well guppies don't count) they'll almost breed with no water! LOL

Yes I know Nitrites are VERY BAD...I know this from learning about the cycle.

Nitrates are still bad for my Discus and I try to keep 0...well tried..LOL

Yah makes me wonder also. I read on another forum people were doing to pretty strange things....needless to say I dont go there anymore.

I have a spawning pair of Discus in my 65 gallon planted tank. I will give it a go at raising them in there. Ive always had a decorated tank with gravel, I am just now getting into a planted tank. Ive only had one fish spawn on me before, it was some sort of Indian barb...I really wish I could find this fish again...but no luck.

I would agree that guppies dont count, my Endlers are breeding without any effort on my part. Now the Discus....this should be a challenge.

One thing I learned to keep in the back of my mind is this is a planted tank forum, with great planted tank advice....not exactly a Discus planted tank forum, although there are some great folks here doing so the advice is obviously plant oriented....sometimes not the safest thing for my Discus.

If you have questions about Discus in a planted tank let me know. I have had my wilds for almost a year now in a planted tank. They have been spawing for months. The babies always get eaten by the tetras though. I actually moved the pair to a bb tank for a couple months, but they lost that lovin' feeling LOL. Put them back in the main tank and they spawned that same week! I really treat it the same as any other planted tank using the logic that what is good for the plants is good for the fish, but it is a compromise I must say for both the fish and the plants. Like the temp for example. Most Discus keepers want 85 to 90 if I recall. Most plants just can't take those temps too well so a compromise has to be make and the temp is kept at 83.

You may also find that with Discus you won't have to add as much KNO3 since they produce a lot in their own.
