    Product was exactly what I ordered and was a good price, however the salts came in as almost a solid unit and felt hydrated to the touch. I had to tap it a few times with a rubber mallet to break it up enough to scoop. This also means that it takes longer to actually dissolve.

    Despite all this it still works as intended.

    Product did as it should, GH has been raised. When I emailed NilocG with a question they responded within minutes. Great!

    Bag came damaged with a hole from shipping. Got support from Facebook and a few days later I received a new bag to transfer the gh booster from the old bag. Fast and great service.

    After ordering and using NilocG’s GH booster I noticed that my plants are doing even better than before. I didn’t think that my plants could do any better since I’m not using CO² but I was wrong! Using Thrive alone really opened my eyes to the fact that Seachem was selling me water and now with the addition of the GH I am getting unbelievable results. Nobody believes that I’m able to get the results that I get without CO² but like I tell everyone. Stop wasting your time and money and start using NilocG’s products! You can’t go wrong… Also a sufficient source of calcium for shrimp and snails.

    This stuff works great. The stuff is hard to dissolve but that is the nature of the beast. if you have soft water this stuff is a must. Even if you do not have soft water you get benefit from it. These guys ship super fast and have the best deals. I only go through them for my plant needs.
