What is the crystalize yellow stuff?

[JBBeaubeaux]

I bought a tank blaster and pushed it down the toilet into the pipe that connects to the black tank. It started knocking off this crystalized yellow stuff in chunks that then fell into the tank. The entire pipe from the toilet to the tank is covered with this stuff and I can't seem to get it all off. Any one know exactly what it is and how to remove it all?

Struvite is a phosphate mineral with formula: NH₄MgPO₄·6H₂O. Struvite crystallizes in the orthorhombic system as white to yellowish or brownish-white pyramidal crystals or in platey mica-like forms.
Formula: NH4MgPO4·6H2O
Solubility: Slightly soluble, dehydrates in dry, warm air
Crystal system: Orthorhombic crystal system
Crystal habit: Euhedral to platey
Crystal class: Pyramidal (mm2); H-M symbol: (mm2)
Formula (repeating unit): NH4MgPO4·6H2O

In other words, crystallized urine?

We use Tank Techs RX. Never did have any buildup, but we’re using it to prevent formation of struvite. Seems to be working for us.

It's what kidney stones are made of.

For the OP, the treatment for your plumbing would be the same as for dissolving kidney stones in the body. Apple cider vinegar should do the trick.
