what water Parameters do i need?


well i have a planted tank and i was wondering what kind of water Parameters do i need to go for? im not 100% sure where i need to have my Parameters at.


here is the specs of the tank: (i hope someone can help me here)

40 Gallon Breeder tank (about 30-32 gallons of water)
2 - HO 39 watts/bulb 6500k on tek 2 reflectors
Lights are on 6 hr's a day every day + 16" from the top of the substrate to the light bulb with a glass lid right under the bulb
pressurize co2
drop checker shows lime green color

Water parameters are:
Ph - 7.1
GH - 7 degrees
KH - 3 Degrees
Nitrate - 5.0 ppm
PO4 - 3-4 ppm
TDS - 200 ppm
Temp - 72-75F when lights are off ---- 79-82F when lights are on for the 6 hr's


heavily planted tank picture below:






some things i need to know is what ppm nitrate and phosphate do i need for this tank? cause i have Green Spot Algae on the glass, not bad but just some here and there and i recently got hair algae also which i have no idea where it came from... if some one can help me clear this issue that would be great... cause i'm not 100% sure what to do or if i am doing it right...

Grab an API fresh water test kit, otherwise you have no way of knowing. Amazon has it for $18 primed. Good luck!

These are from an article Tom Barr wrote several years ago. Many of the ranges can be higher than this without problems. It's a decent range to shoot for. As far as CO2, I would adjust that as high as possible without causing distress to your fauna.

NO3 (nitrate) range 5-30ppm
K+ (potassium) range 10-30ppm
PO4 (phosphate) range 1.0-3.0 ppm
Fe (iron) 0.2-0.1ppm
GH (general hardness) range 3 degrees ~ 50ppm or higher

i know that i need a test kit to test the water but thats not what i was asking in my op, and i do have a test kit already too... -.-

these would be the general rule of thumbs, but from what you see above is there like a more narrow Parameters you would recommend for this tank?

You're asking about water parameters yet not testing your water parameters?
Sounds like you're on your own......

i'm asking for options on what people keep their tanks at or what they think my tank should be at.



i will test my water tmr and have that info tmr in the op

If you're asking for fertilizer concentrations? If it's a high-tech tank, just go for EI dosing.

If you're talking water parameters like the ones from your tap? That depends upon your tap itself. There is no real target people aim for unless they have really low GH or something like that.

Your tank looks great to me. Whatever you're doing seems to be working. I'm not aware of one magic parameter list that works for all tanks. The previous ranges are good for the majority of situations.

The parameters can vary depending on water changes. My low tech is more stable because I do water changes every couple of months using very hard tap water. The parameters I do test are approximately;
  • ~20ppm nitrate
  • ~3ppm PO4
  • GH 11 degrees
  • KH 13 degrees
  • ~PH 7.8
My high tech tank varies because of large weekly water changes using R/O tap mix and EI dosing.
  • ~10-50ppm nitrate
  • ~2-5ppm PO4
  • GH 4 degrees
  • KH 4 degrees
  • ~PH 6.5
  • CO2 set just below fauna distress 45ppm?

so i just got done with testing my tank water and here are the results, let me know what is lacking or what i need to do to fix it if needed, also if there is nothing wrong then why are the Green Sport Algae and hair/thread algae?

Water parameter of the tank is:
Ph - 7.1
GH - 7 degrees
KH - 3 Degrees
Nitrate - 5.0 ppm
PO4 - 3-4 ppm
TDS - 200 ppm
Temp - 72-75F when lights are off ---- 79-82F when lights are on for the 6 hr's

am i missing something?

Your nitrate could stand to be a little higher over 10ppm. As far as the algae, increase your CO2. Drop checkers aren't a very accurate way to judge CO2 concentrations. If you look at a CO2/KH chart, which again isn't 100%, you're well below optimal; around 8ppm of CO2.

The one sure way to dial it in is watch your fish, plants and algae for a response. Increase the CO2 output a very small amount and watch the fish/shrimp. If after 2-3 days you see no change repeat that increase. Do this until you see signs of distress, gasping at the surface, lethargy or any erratic behavior. Then reduce it to the output previously. It takes time so don't rush it. That will dial it in better than any testing method available.

the co2 lvl u see is just an early start not at full time on, i will test the kh and ph again once co2 has turn off and i'm sure they will be at the right place it should be. i will post an update on that soon

Did u use a GH/KH test kit?
Also is that just black sand in your tank?
