Didn't you name the fox face I got from you, Fang?

Is this Fang-Jr?

I don't measure the effluent Alk. I control to the pH inside the CaReactor, to control the melt rate of the media inside. If you've got that control, you could try lowering the pH. (my reactor isn't setup as a constant bubble supply. instead, Apex turns on/off the CO2 solenoid based on the pH inside the reactor. If your system is setup with a constant CO2 bubble rate, you could just increase the bubble count) BTW, I find my CaReactor can't keep up. My coral mass is now Large. At @goldenbasketreef recommendation, I supplement with Kalk water. In my case, my ATO water goes through my Kalk reactor - which I do only at night. Balances out the pH swings as well. And in case you're wondering, I'm using ReBorn media in the reactor, and control reactor pH to 6.3-6.5, with a 5 minute minimum On time for the gas. Results in pH between 6.3-6.38

MILESTONE: Harvest #50 complete (Aug 16th) Easy Summary, no change to procedures, same good results, including 100% Poseidon Reef Fertilizer. I've had a request to show culture color Before Harvest, and After restarting. Before Harvest: After Restarting: The Harvest:

Welcome to the group, nice looking tank. I see the GHA, but I also see some good cleanup items (tang and urchin). At the same time, I see a Damsel. They've been known to protect and nurture GHA fields, by harassing's your cleanup crew to stay away. Do you see any of those behaviors?

Thanks everyone for coming. We had some great conversations. Thanks to @Lexinverts for the LED, lighting, and par meter talk. I'll admit, I learned something, quickly checked my led settings, and tweaked them live during the talk. (pulled down some red) Thanks Andy!

Next time! Next time I'll win the special raffle frag away from you!

Sir, you've got some awesome skills. Well done.

Yes, looking forward to meeting you!

Everything at once. (okay, my pipet is 2.5ml/squirt - so it's spread out across the time it takes me to do three squirts) And right now, daily chems are added manually - between 4-6pm-ish. One after the other. Currently daily chems are: Iron, Manganese, Chrom, Cobalt, Iodine, Selenium, Copper, Tropic Marin NP bacto balance (carbon dosing)... and now Ammonium Bicarbonate Due to large coral biomass in my system, I feel I need more Nitrogen than currently provided. I've been dosing Brightwell NeoNitro to keep my measurable NO3 in the 5-10 range. But it sounds like Ammonia can provide nitrogen in a more consumable form. @Lexinverts shared his experiences https://www.pnwmas.org/forums/topic/53523-ammonia-dosing-in-my-reef-tank Recent discussion https://www.pnwmas.org/forums/topic/54880-diy-ammonia-and-alk I been interested since last year, but really wanted to do this while able to track NO3 and PO4 more actively. Thus I've waited until getting the trident NP. https://www.pnwmas.org/forums/topic/53055-anyone-dosing-ammonia Some Main Reef2Reef discussions: https://www.reef2reef.com/threads/diy-ammonia-dosing-for-low-nitrate-systems.987087/ https://www.reef2reef.com/threads/ammonia-is-our-friend-thoughts-needed.1066535/ Here's how my Nitrate has trended over the past week. My last NeoNitro dose was July 25th, which raised NO3 up to ~9. You can see it's being consumed at a steady rate.

Status as of Day 3 of Ammonia Dosing. Observations: No negative effects seen Also, no magic "OMG the tank looks different" Trident NP Nitrate says Nitrates continue to be consumed on a daily basis (same as before) I believe this is as expected, the challenge of ammonia dosing is figuring out what actual amount is not being consumed. @Lexinverts - Do I have this right? My notes, for this activity; 8/4/2024 My stock soln is stronger than R2R article, (20g in 500ml, vs 20g in 1L) https://www.reef2reef.com/threads/diy-ammonia-dosing-for-low-nitrate-systems.987087/ 8/4/2024 Ammonia solution: 20g ammonium Bicarbonate in 500g RO water. Work up to 0.08ml/gal 8/4/2024 planned schedule: Week1: 7ml/day (0.02ml/gal) --> Week2: 14ml/day (0.04ml/gal) --> Week3: 21ml/day (0.06ml/gal) --> Week4: 28ml/day (0.08ml/gal) 8/4/2024 FIRST DAY - Ammonia Dosing. start with 7ml / day to begin with ... should be 0.02ml/gallon (on 350gallon tank) Currently here --> 8/11/2024 SECOND WEEK - Ammonia Dosing. Increase to 14ml/ day (was 7ml) ... should be 0.04ml/gallon 8/18/2024 THIRD WEEK - Ammonia Dosing. Increase to 21ml/ day (was 14ml) ... should be 0.06ml/gallon 8/21/2024 FOURTH WEEK - Ammonia Dosing. Increase to 28ml/ day (was 21ml) ... should be 0.08ml/gallon

Soo generous. Appreciate the offer.

What's the Alk of your freshly mixed tropic marin salt? I see the words "coral pro" ...

You'll never guess what's arriving today... I've held off switching to Ammonia dosing, waiting for a daily automated tester (Done. Trident NP) and confirmation I can use the daily trend information to figure out if I've screwed up big time. (I'm feeling okay on this now, for NO3). Expect Ammonia dosing to start next week. From Andy's post: mix 20g in 500ml of RO water Mike and Sanjay are dosing .08ml per gallon, but they worked up to this dose slowly and carefully Andy started dose at 7 mls per day for 200 gallon system (0.035ml/gal) worked up to 16 mls per day over 2 weeks (0.08ml/gal) I'm thinking of starting even more slowly. And stopping if I'm watching NO3 increase. I'm a bit worried about trident not reporting PO4 crisply, and may have to manual/hanna test that more often. To keep my N/P ratio up. 7ml/day - for my 350-400gal system (0.02ml/gal) 14ml/day - for the next week (0.04ml/gal) 21ml/day - for the next week (0.06ml/gal) 28ml/day - 0.08ml/gal

Got my latest Oceamo ICP-MS test back. Trident NP is doing great for Nitrate, still reading a touch low for Phosphate. Here's the Timeline of measurements/activities. July 21: Trident NP @ 1pm NO3 = 4.5 PO4 = 0.02 July 21: Hanna @ 5pm NO3 = 4.2 <- confirms trident PO4 = 0.043 <- double trident July 21: Additives @ 6pm +100ml NeoNitro, +100ml NeoPhos July 22: Trident NP @ 1pm NO3 =5.3 PO4 = 0.02 <- looks low July 22: ICP-MS, sampled @ 6pm NO3 = 4.6 <- trident is clearly close enough PO4 = 0.05 <- confirms trident still low, Hanna is closer
