I made the switch away from MD to BRS for all of my reefing needs many years ago because of poor customer service on the part of MD. There is absolutely no comparison in the customer service between MD and BRS, BRS blows them out of the water. My most recent experience was with replacement blades I ordered for the Hammerhead Float I bought from BRS. They have some blades on the site which are not compatible with any of the "plus" algae free scrapers, which is apparently what I have because the Plus version is all they sell. Long story short, I ordered the wrong blades but BRS agreed that it is confusing and is shipping me the correct blades. Thanks again @Bulk Reef Supply
