Other factors might have to do something with it, like NO3 level and the lighting intensity. Some says lower NO3 level and intense lighting will bring out the red followed by some Fe dosing. But of course running lower NO3, you at risk inducing BGA. Everything have to be in balance.
By the way, what is your NO3 level (ppm) and lighting (wpg). Care to share and help bring out the red?.

Hi Nasfish,
After I read what you posted, I i felt that i'm wrong and confused too
But anyway, just something more detail...
I'm having a standard 4ft tank, DIY co2, but i'm too lazy to measure the ph and kh to get the readings...
NO3 level...i'm not sure cause i don't have the tester.
I have 5 x 36W FL with diy 2 reflectors. so roughly about 180W, and WPG calculation is roughly about...
180W devide by 60G = 3 WPG
When they grew red, that time i only dose Ferropol after water changes, and Ferropol 24 everyday. Calculations shows that i need around 5-6 drops everyday, but i increase to 7-8 drops everyday, so over dosing it as i don't add any other ferts since i have 11 neon tetra, 2 albino cory, 1 CAE, some feeder prawns, 6 yamato shrimps, 2 otto and plenty of snails. I think they could generate reasonable amount ammonia, KNO3 and i over feed them to get more PO4.
But then after a water change disaster, 50% water change killed all my neon tetra and my newly bought 2 SAE, so we can see how bad is our water, and my area is affected with the smelly water case, and these days we have ALOT chlorine in our water, I can actually smell it when i'm taking bath, feels like at the pool side. So then I rescaped my tank and i bought 11 cardinals this time, 2 SAE, 1 banana shrimps, and 5 cherry shrimps.
My ferropol 24 is used up, so i haven't buy it yet. Now i only dose rough ammount of KNO3, K2SO4 and KH2PO4 to my tank, using fert calculator to calculate the targeted ammount, then i measure them and mix with water, and then apply to the tank. So i dose the 1/5 of the targeted amount everyday 3 days, and dose 1/2 of the targeted ammount everyday water changes. I also dose Epson Salt now. But i'm sorry to say that i don't have all the measurements of the water parameters. I'm Sorry
So now, i only does the above mentioned...no additional Fe tabs or Ferropol 24 use for now. But i'm interested to try out the Hagen - Nutrafin Plant Gro Iron Enriched, i saw it with a newer series, that promise to have more Iron in the bottle.
Regards,
John
