Keep a sequence of planned and performed water changes, compare nitrate dilution estimates with actual after-tests and preserve the assumptions behind the plan. HOW IT WORKS 1. Open Tools and Water Change Journal. Verify net water volume, starting nitrate reading and its date. 2. Add changes with replacement volume and source-water nitrate. Mark a change performed only after doing it, and add an optional actual after-test. 3. Review the chart and sequence, save the journal and share the record. Tank records, tests, maintenance tools and references remain available. The calculator now flags source water that cannot reach the requested nitrate target. An unreadable tank store blocks replacement and preserves the original file. WHAT TO KNOW Dilution assumes uniform mixing and no new nitrate production or removal between steps. It is a planning estimate, not a recommendation about a safe change size. Actual after-tests become the next starting value. Use measured net volume. Up to 12 changes per journal and 100 journals. pH is no longer offered as a linear dilution calculation. iPhone and iPad.

That moment when your mind goes blank in front of someone you like. Practice with Rapport, and next time you'll be more you. Rapport is a conversation practice app for first dates, casual drinks, and meeting new people. Talk out loud with an AI partner who reacts like a real person — then get warm, honest feedback afterward. ◆ Voice conversations that feel real Tap once and your practice date begins. Your partner laughs, asks you back, and even loses a little interest if you fire off interview questions — just like a real person would. ◆ A partner whose face responds Their expression shifts with the conversation. Watch them burst out laughing at your joke or get shy at your compliment. ◆ Honest feedback when it ends Speaking ratio, open questions, empathy moments, missed emotional cues — observation, not lecture. You get exactly one skill to focus on next time. ◆ Choose the situation and the person First date, casual drinks, an evening walk, or free talk — practice different temperatures of conversation with distinct personalities. Prefer typing? There's chat mode too. ◆ Your conversations are never stored Practice sessions aren't saved anywhere. When a session ends, only your feedback remains — the transcript disappears. Practice honestly, without pressure. Rapport Plus includes 100 minutes of voice practice per month. Subscriptions can be cancelled anytime in Settings and are billed to your Apple ID.
