First line of the third bulleted paragraph and I quote:
"Minimize nutrient levels with frequent water changes."
Algae control in the aquarium
"Phosphate
Phosphate as a by-product of mineralization of dead matter such as plants, bacteria, feces, uneaten food, fish slime etc. are all internal contributors.
Dead plant material or rotting food particles settle either on the
substrate or within the filter. Rinsing filter materials and vacuuming the aquarium
gravel at every
water change can significantly reduce potential
phosphate accumulation from these internal sources.
Silicate
The most common points of entry are the substrate, salt, and water. Please keep in mind, that R/O and D.I. units (filters to purify tap water by membranes or by chemical/ mechanical processes creating distilled water) will prevent silicates only for a few days, before they find the way through the membranes.
Another form of silicates is silicid acid, created by decaying organic matter. Same as
phosphates, they can be water insoluble at a high pH, and become readily available with decreasing pH levels."

Those are just 2 of many articles I found by using a simple google search of "how to reduce
high phosphates and silicates in a fresh water aquarium".
Notice the trend of "do water changes"?
Wendi,
Just because the water change isn't on your doctor's invoice that doesn't mean the company doesn't do them. My LFS and I myself offer these same services and neither of us put water changes on our invoices. I put them under " general tank maintenance" and they put it under "other package included". So you can't honestly say for sure if PWCs are being done or not.
Secondly, as you do promote water changes, perhaps you should understand that dilution is the solution to pollution. The more you do a water change, the more you are removing the other issues that cause the outbreaks of diatoms/algae/ammonia etc.
Since the OP has issues with doing regular maintenance on his tank, he is in essence causing his own problems.
Until he either
A) gets a grip and starts a regular maintenance schedule instead of shooing away the great advice that many people have given him through out his self-made saga
B) finds a company to hire that does these types of services
C) re-homes the fish and dismantles the tank
he will continue to have issues and judging from all his replies in all his posts, this one included, he will continue to ignore advice and egg people on.
