This is myth about PO4 = algae in planted tanks.

It's no myth Bob. If I maintain measurable Phosphate, any
measureable phosphate, I get algae far in excess of it's
normal rate. That's a long established and infinitely
repeatable fact. I assure you, because of my setup and lack
of any substantial bio-load, Ammonia is as non-existant in
my tank as it is likely to be in any tank, anywere.

Buyer Beware.

What type of algae are you getting, BBA?

That's a long established and infinitely
repeatable fact.

What's your tap water like? Phosphates?

Too late Its a done deal.

After 10 odd years, I'ved ended up innoculated with green
spot, green water, and green hair. All well managed.

That's a long established and infinitely

repeatable fact.

Phosphate present at .25mg/L.

of any substantial bio-load, Ammonia is as non-existant in
my tank as it is likely to be in any tank, anywere.

My warning is only that people with serious money
investments should think twice about nonsense like suddenly
dosing their tank to bring phosphate anywhere near 5ppm
levels, just to learn a lesson. Indeed, suddenly dosing
anything in excess may quite likely teach them a lesson
they'd rather not have learned.

Plants need phosphate. They do. Most get enough in
food/tap water changes. If not, then small doses are surely
needed. Better to tackle the issue in the PMDD style. Then
does additional P if, and only as, needed.

P is also rate limiting for plants. If they lack an
abundance, they simply stop/slow growing. Nice that, once
you've planted and pruned you tank to perfection - and want
it to stay that way for awhile.

My version of Bob's experiment would go like this:

1) Dose your tank to PMDD specs for a couple of weeks.

2) Buy a bag of Phosphorus Pentoxide (P2O5, Super Phosphate)
and make a stock solution of a scant 1 tbs per pint of water.

3) Having achived appropriate levels under the PMDD regimen,
slowly dose your phosphate stock until you see your front
glass getting cloudy more quickly.

Slowly, in my case, would be about 1-2ml of stock per 135G
tank, per week, max. This tank is also subject to a
continuous 5-6 GPD water change regimen. This results in a
spike, detectable by testing day 1, and non-detectable
within the week.

Generally, tho, I don't does P anymore. Overgrowth is as
bad as anything else, and just another maintenance chore.
