Welcome to the forum! although nano tanks are not usually the culprits, red sea has a well-documented history of tank seam failures and making it difficult for hobbyists to get refunds or replacements. Just search for "red sea seam failures" to see horror stories. Don't spend your hard-earned money on red sea tanks, at least until they prove they care about their customers.
