Ive been in the saltwater aquarium hobby now for about 7 months. Ive had my downs and finally my ups. I have lost more high end SPS than I care to admit to myself. I've recently bought a dosing pump (cheap Jebao) and have begun to dose B-Ionic Alkalinity & Calcium. Also going to start supplementing AcroPower weekly. Purchased an APEX system to keep things automated and this is a real game changer vs manual dosing, etc.
So to my main question. What makes a stable tank? When I first entered the hobby I understood what stable meant but not in an aquarium sense. Let me see if I have this correct.
(These numbers may vary from user to user, this is what I believe is right for my tank for the research I have done)
1. Keep pH at 8.30 without major fluctuation.
No, and trying to keep PH stable can cause BIG issues Mine varies from 7.75 to 8.5 depennding on the time of the year. Typical daily variation is 7.8 to 8.3.
2. Keep Calcium at 420 - 430 by dosing daily. Increase dosage as you add corals or corals grow.
Test Alk and dose a balanced 2 part, Kalk, or use CalRx to maintain.
3. Keep Alkalinity at 9 - 10 dKH by dosing daily. Increase dosage as you add corals or corals grow.
I would target 7 and not vary by more than .2
Most important with KH in my experience ... falling too low annoy and if not corrected eventually will hurt acros, rising too high too fast, especially when nutrients are low, will cause significant long term damage.
4. Keep Magnesium at 1350 ppm by dosing.
5. Keep Salinity at 1.024 - 1.026 (Check a couple times a week with refractometer)
I see no reason to vary from 1.026
6. Use ATO with clean and fresh RODI water to maintain salinity
7. Do weekly 10 -25% water changes. (Fun, Fun, Fun!)
8. Keep Temp at 78 (use quality heater controlled by APEX)
9. Keep phosphates at 0.03 (run GFO and clean tank weekly or bi-weekly)
.03 - .06 works ok for me. Stable PO4 is also critical so be careful with GFO, especially if PO4 get's high. A quick downward swing can cause a lot of damage.
10. keep Ammonia and Nitrate at 0 (should never really be an issue since no fish are present)
11. Keep Nitrate under 10 ppm. (will be managed by weekly water changes)
12. Dip all corals to prevent pests, RTN, STN...etc
Since this is the SPS forum, I would only dip in Bayer, break off frag plugs, and inspect for eggs. I do not believe in dipping after the initial pest dip but it's a personal preference.
Am I missing anything?
