My ammonia is now almost undetectable, and nitrites are pretty high, around 3ppm. I dosed a tiny bit more ammonium chloride today, but I think I'll now stop dosing until both ammonia and nitrites drop do below 0.2ppm. Once that happens I'll try dosing more ammonium chloride and see if the levels go down to 0. I'll keep waiting for 0.2ppm drops to dose until both are undetectable.
My Skimz QuietPro 4.0 DC pump and 2.0 DC pumps are pretty loud. At 40% my return pump registers 55dB. I asked BRS if I could return them and they said yes. I'm replacing them with Reef Octopus VarioS S-4 and S-2 pumps. They're a bit more powerful, but they can be controlled down to fit the bill. I'll be running the S-4 at around 550gph, and the S-2 around 250gph. I was originally going to go for the Vectra S1 as my return, but I keep seeing broken down M1 pump threads pop up. Even though replacements and what not are sent out quickly, I have yet to see any problems with VarioS pumps. Skimz users say their pumps are really quiet. VarioS owners say it's dead silent, and there's no noise at all. So I'm hoping for the best.
I don't really need to control these with Apex, other than on/off. I'll have the return on the Apex Jr.'s eb4 outlet, but the skimmer/reactor VarioS S-2 pump will just be on a powerstrip. I'm saving the last outlet I have for my algae reactor light (turning it off if things get too hot).
I'm considering getting an eb4 or even an eb8 to control:
1. Heater
2. Chiller
3. Return pump
4. Reactor/Chiller pump
5. Algae reactor lights
6. Skimmer pump
7. Gyre pump
- I'll probably also eventually get an auto feeder. Then my Apex would turn off the return and skimmer pumps, feed, and then turn on the return and skimmer pumps again. Good for when I'm not in town (which will be often)
- I want to control the algae reactor lights to be opposite of my AI Hydra, so a simple time based on/off would work here. I will also have a heat failsafe, so if the heat gets too much (like beyond chiller ability) I will shut off the reactor lights
- If leaks are detected, I'll probably have everything except the gyre pump stopped and an alarm sent. If anything, I have a nest cam that I can look through or call someone to go over and check. The gyre pump should keep things alive for a bit.
An extra FMM module from my ATK for a total of:
1. PMUP
2. ATK sensor low
3. ATK sensor high
4. LD-2 leak probe (in cabinet)
5. LD-2 leak probe (behind cabinet on floor)
6. Solenoid to refill 5 gallon ATO reservoir
7. OS-1 optical sensor for ATO reservoir low
