I know this thread is over two years old but I wanted everyone to be aware of a similar problem that is occurring with my Marco Rock. Approximately 6 months ago, I bought 200- lbs of Marco Rock (all shapes and sizes) from BRS. I spent considerable time cleaning and soaking the rock to get all the dust and fine particles off. I then spent over two weeks getting my aquascaping looking ”just right”. My tank is 365 and has been running now for 5 months. Recently, I noticed a lot of small pieces of Marco Rock all over the bottom of my tank (bare bottom tank) along with a large amount of granular dust particles that are starting to make the tank really unclear. The rock clearly has something wrong as no matter how much time I spend sucking-up the fine particles on the bottom, a couple days later its covered with fine particles again. I thought when I bought Marco Rock from BRS I was getting a highly reputable/quality product. It really doesn’t do any of use any good to hear we “might have gotten a bad batch”….NO batches should be bad for what we spend on this rock. It‘s so painful to see what’s happening as I have patiently done everything by-the-book in setting-up my new tank.
Stuff happens. These days it’s more frequent. Cost, quality, speed. Choose two kind of deal particularly in this age.
Have you ever owned a home, or a card or anything else that is more expensive and that has had problems? For what we pay, those things should be flawless and last!
What is the threshold for when bad QA is acceptable? 100,000$, 10,000$, 1,000$, 100$, 10$? Even video games are released these days with seemingly more bugs than promised features.
I’m not saying it is okay. But I am saying that people saying “bad batch” may not be wrong. If you determine and can agree that is the issue, then your beef is with the product and the manufacturer. Call them.
