hi i need help to reduce my PO4...
My PO4 is too high, all my green, brown and hair algrae is growing...

I don't think PO4 causes algae bloom. Perhaps you can give us your tank specs in order for us to help you see whats the prob?Originally Posted by com996
A noob & poor aquarist
Please fill up the tank spec form so that people in the forum would have a better understanding of your tank before quality advise could be suggested...
How much were you dosing?
Tom Barr's Estimative Index shows he dose 1.0pmm to 3.0ppm PO4 weekly. And he reported plant uptake of PO4 is 0.2-0.6ppm in 24hrs in a high light/OC2 tank.

yeah overdosing of PO4 in substantial amounts might lead to an algae bloom. I am currently dosing 2.5ppm per week and everything is fine. I tried to O.D once 6.0PPM per week before my rescape as an experiment and found that GSA take over my tank walls but on the plants as well.

No. It does not trigger algae...bark up another tree.

Probably I was lacking in the CO2 department then? After my rescape, I've maintained my schedule but pumped the CO2 to have 30PPM currently and algae free for the time being.
Anyways, truth being that PO4 does not trigger algae is indeed correct, in excessive amount, I don't really know, just gonna play safe for myself. Perhaps the experts can enlighten you further com996

Algae happens through many many many ways. com996, we need more information on your tank setup. Give us as many info as you can.
Thks friends,
Well my tank is (4*2*2)ft
Abt 400l
Lighting 4*55w PL
right now my hair algae is blooming.
Some of Shop owner adivce me to measure Kh... is it necessary?
What are the thing to take note and what are the thing to be measure; CO2, Kh,PO4....
thanks..

You must ask yourself, what is the reason for measuring the kH?
Please, fill up this form and post it here.
We will tell you how to rectify your problem. Meanwhile, do a good clean up of the algae, buy new plants if you need to throw away the algae-infested ones. Increase your CO2 bps to the point where fish do not show signs of distress. Do this slowly day by day, slight turning of the regulator knob only.
apparently the shop owner needs to log on to AQ more often..
i'm ADDicted to this wonderful hobby
Thks Terence,
But if i increase my CO2 will my green and hair algrea grow even faster?
rite now i i'm using CO2 reactor, and haf decrease my filter flow rate..
will it help?
Thks

No it won't. It'll help your plants, which will help in fighting off the algae. Good plant growth = poor algae growth. Nitrate and phosphate do not cause algae. Ammonia and its compounds will trigger algae. Algae will not go away after it hsa grown, even if you have corrected conditions. You need to remove it physically; harrass it.
Decreasing your filter flowrate doesn't help imho. Why would it help? Plants need a mild current to bring nutrients all around the tank so it comes into contact with their leaves.
1. Clean up everything real good. Whack the algae hard in the face. After all the cleaning, do a 80% water change. The next week, clean the filter's mechanical media. If a plant is too infested to be cleaned properly, throw it away and buy a replacement.
2. Increase your CO2 little by little day by day until fish show signs of lingering at the water surface/abnormal behaviour, then turn back the knob a bit so that you get the maximum rate of CO2 you can bubble into your tank. Make sure water flow is good so that CO2-enriched water gets to all parts of the tank. There should be pearling/bubbling from the plants at the end of the day if your tank is growing well. This will eliminate the CO2 factor from the list of problems.
3. Next, get fertilisers: KNO3, KH2PO4 and Seachem Equilbrium. They can be bought from Nature Aquarium opposite Thomson Medical Centre. Dose 2 teaspoons of KNO3 and 1/4 teaspoon of KH2PO4 twice a week. Dose 1/3 the recommended dose of Seachem Equilibrium weekly. Do 50% water changes weekly. This eliminates the fertilisers problem.
4. Make sure your temperature is below 29 degrees Celcius. Make sure water surface movement is very slight. Make sure your tank is fully planted, not just planted with a few stalks of plants and wait for everything to grow. Plants are cheap in Singapore, buy them en masse. Change your light tubes at least once a year.
The above should get your tank back in shape. I realise I've just given straight instructions, no explanation whatsoever. Feel free to question me.
The above "instructions" might be wrong too, do take note of other people (especially PeterGwee) if he posts her. He's the guru on algae problems.
