I purchased 15 lbs of LR for my 10g Nano and Philipp shipped it to me in WATER per my request. It was more expensive to ship but WELL WORTH IT! I had absolutely NO die off. Tons of brittle stars and even an impressive crop of bright orange sponges that are still alive! I saw maybe a slight bump in NH4 and a max NO4 of 10. It has been less than a month and I already have fish and inverts with perfect parameters. I can’t recommend this stuff more highly! Purple corralline still looks gorgeous. Thanks a million, KPA.
