Reef nutrition

Rostatos Reefer 450 and Reefer 170

I didn’t see any. I can’t see how anything else would quiet it down. It’s mounted properly
What I remember it was about hownirs mounted, something about reducing the vibration which reduce the noise.
If the noise coming from the peristaltic head rotating or is it from the vibration of the pump when ita dosing?
 
That’s about what it sounds like. By far the loudest thing on my tank.
Lol Man 2 feet away from the stand i do not hear it.
But I get it, look like its the regular level.
This is large peristaltic pump, that's typical noise level. Stenner is way way louder as an example..

I can here it with the doors closed and be all the way in the other side of the house.
 
A little over 3 weeks with the dastaco and here are my thoughts.

I’ll give the bad first, and then the bad.

Bad
1. The manual was very confusing, but not impossible to figure out.

2. They should tell you to read the entire manual before you buy it( and you can’t get a manual until you buy it). There are a few quirks to this reactor that I was not anticipating. Example? The line from co2 solenoid to co2 chamber, and reactor to sump lines have very specific lengths that they need to be or the reactor will either alarm for or simply just not work properly. This made the install very difficult for me, and I needed the help of creative minds on the Facebook group To make it work. You really need this thing to be right next to your sump for it to be a see less install.

3. You must use either triton or dastaco pure media because the ph in the reactor is so low. So no trace elements are entering the tank from the media, but also no impurities going into the tank. So maybe a plus, but I consider it a negative. Now I’m dosing tritons infusion elements. I’ll have to send an ICP soon to see how it’s doing.

4. Can’t use remag. See#3. So now I have to dose magnesium

5. It’s by far the loudest thing on my tank. I’m not saying it’s loud because I don’t mind it, but it’s the thing that “sticks out” sound wise on the tank. Before this, it was my old MP40’s with the old dry side and the QD driver and wet side that were the loudest thing on the tank. The loud part is the peristaltic pump. It kinda grinds while it runs. I guess it’s nice to know it’s working...

6. So far my dkh is more unstable. I’m not sure why, but I seem to get much larger dips In my dkh (in the realm of around .5-.7 dkh) every three hours during he peak daylight times. I didn’t have this issue when using 2 part. I know I’m still tuning it, and I expect it to be better soon, but it’s been tough to keep the dkh from swinging too much. I’m just glad that I have my apex programmed to turn back on my 2 part dosing to supplement when needed.

7. I had to disconnect the light sensor. This measures the intensity of the light and reduces the dkh output accordingly. Sounds great, but when I had it plugged in, my dkh was plummeting almost 1 dkh overnight. So I unplugged it.

8. The low ph effluent made me have to turn up my co2 reactor, so I expect the media to last about a week less than before.

9. My ph is about 1 point lower than it was before adding the reactor. Before it I would peak around 8.4, but now I’m peaking around 8.3.

Good
1. Set and forget. I’ve had zero alarms or issues. It just works.

2. Easy to dial in. Just turn a knob. I’m almost at setting 5 of 10 with zero overdrive yet.

3. Everything I needed except the co2 tank was included

4. Great support. My Eheim pump impeller housing was broken and they sent out a replacement fast.

5. A very active and very helpful Facebook group.

6. Did I mention, set and forget. No ph probe calibration...nothing

7. My salinity is much more stable

8. I don’t have to worry about my 2 part reservoirs running out if I go on vacation. I was dosing so much two part that my reservoirs would only last 8 days.

9. The corals seem to like it. They are already growing a bit faster than before. But there could be other factors or I made up in my head. Either way I’m happy so that’s all the counts.

10. It has an audible (very annoying) alarm with different tones to tell you when something is wrong. This is awesome!

It sounds like a lot of bad, but most of those are just inconveniences that I expected. My salinity is more stable and that makes me happy.
Were you doing water changes when you used only two part? I never noticed a salinity increase
 
If your salinity is shifting because of your additives, how would water change have any effect here? Unless if you start shif5ing your water mix which is absolute pain.
Because the water you're replacing should have a lower salinity than the tank water that's increasing from the 2 part. So it should keep the salinity in the tank from increasing very much. There's also some water being pulled out by the skimmer that is replaced by freshwater.

I'm at 90ml/day for 2 part and my SG in the tank is 1.025 vs 1.026 in the mixing station. I change 10% of the tank water per week.

i know how to quiet it down, grab the whole unit and toss it out the window. :oops: & go back to dosing.
lol
just kidding, it sounds frustrating. I hope you figure it out. Good luck

I’m not sure why, but trust me. My salinity was always creeping up.
 
There’s sodium in part one and chloride in part two, when the carbonate and calcium are used these combine to make salt in the water.

but there’s also the fact that when you measure the salinity it isn’t only salt, it’s also the other elements in the ppt that are measured so adding two part will increase those values, but obviously the idea is that the coral is using up most of what is being added.

but that’s just my understand and I’m no chemist so someone else may be able to explain better.

All I know is that my salinity would slowly rise from 1.026 to 1.028 within a month. Water changes don’t really help if you changing with 1.026 water.

I also know it’s been 3 weeks with the reactor and my salinity has not changed.

I use the Milwaukee digital reactor.

The idea is the frequent water changes keep up with the rising salinity so it doesn't rise that much to begin with. I'm not sure what the calculations are to determine how much you need to change per week to keep up with the rising salinity.

"Dosing 4.4 dKH of alkalinity per day (and the equivalent calcium part) will raise salinity very roughly by about 0.2% per day." Maybe your demand is so high that the water changes just can't keep up. Were you also using ESV b-ionic? What's your dKH use per day?

I’m not sure how much it will use per day because I’m too scared to figure it out. All I know is I was essentially dosing 2 part non-stop all day.

even with the calcium reactor and the 2 part dosing going during peak periods the tank will still drop over .5 dkh in three hours.
