Hi, I’m new to saltwater fish and I think I researched everything to get started, but either we had bad luck or I’m missing something in the tank. Here is how I started,
37 gal tank 30x15x22H
Live sand
Live and dry rock about 25 to 30 lbs
AC70 filter
Heater
Red Sea salt mix
Sicce nano 2000 pumps X2

I cycled the tank fishless. Use ammonia and bacteria.
After completing cycle I did a water change. Checked water parameters and everything was in range whether it be mid or high in range. Salinity was 1.025 to 1.026
Day 1: We got some corals and a pair of small clownfish from non chain FS that had a bunch of saltwater fish. it was about 1.5 hr drive home. I acclimate only by floating bag and because I kinda saw one fish not moving as much. Once I put the fish in the one that was not moving as much was having trouble immediately. At this point we only had one sicce pump on. They seem to have trouble swimming in flow. I placed the pump to face current away hitting a glas to get flow away from them. A few hours later the small one died. By morning the other one died. I tested the water they came in and salinity was fine and close to mine. Only kh,mg,ca were higher than recommended from the reading I had done, but I don’t think that would be an issue for them.

Day 2: I checked the water parameters and seemed fine, no ammonia or nitrite. I did a water change just in case. I went to a local chain store and got a pair of slightly bigger clown fish. 40 min drive home. When I got home I floated the bag, this time I was going to add some tank water to the bag to acclimate that way, but when I check salinity in the bag it was 1.001 or so. I triple checked it. I checked my tank and even calibrated the refractometer. That was salinity in the bag. I started slowly adding tank water to bring up salinity slowly without leaving them in the bag too long. I don’t know if the store did a mistake and added freshwater or their tanks are messed up. It is what it is at that point. Once I added them to the tank they seemed fine but would hang out in an area for the most part.

Day 3: they both made it to morning, later I added the second pump for corals going by that one would not be enough flow but to me it seemed like no matter how I placed them it was too much flow for the fish and later even seemed to much for the corals as a whole . Mostly lps and a couple soft. So most of the day I had both pumps. In the evening I turned off one because it just seemed to much for the fish. I noticed that the bigger of the two would stay in place more.

Day 4: I woke up to find the bigger of the two fish dead. We can’t figure out what is going on.

Ideas:
1. the pumps which are 530 gph each were and are too much flow, maybe even one at 530 gph seems too much. These pumps are stream pumps could that be it?

2. Could it have been the salinity in the bag being low?

can anyone say if we are missing something to check as nothing looks or tests abnormal. Besides the flow of pumps.

We are holding off getting fish until I can figure this out.

Welcome to Reef2Reef!

One thing, and I think you already picked up on this, at last the second fish went through a tremendous rise in salinity. Fish don’t handle large rises well. I suspect that this played a role in your first losses as well.

Another thing - any fish transport in bags, longer than an hour or so, should be in oxygen, not room air.

Here is an article I wrote of acclimation:

https://www.reef2reef.com/ams/acclimation-methods.903/
 
With the salinity I had a similar experience. 16ppt measured. Fish were deliver via package.
I removed some of the water from the bags and over about 40-50mins, I added a bit (around 200ml) every 2 minutes and reached 30-31ppt. Then I transferred the fish, and they were fine.
It looks bad that your fish were struggling in the bag already.
The store recommends a different procedure (I wrote in another thread I wont watch their video but I did) - basically adding a lot of water from your tank a few times - I did not follow that.

welcome to reef2reef!
I agree with Jay with the salinity swing likely being the cause of death
as far as the pumps, controllable pumps would help greatly so flow can easily be adjusted
 
I think you found the issue yourself - good for you - the salinity from the fish store was much lower. Fish stores commonly do this to suppress disease, so its important to test or ask before leaving the store what the salinity is. Often it requires a few hours to match the salinity safely.
 
Yes, definitely would be asking every time before leaving the store for test. So if I’m understanding this correctly

First fishes that passed was most likely the travel stress?

Second time fish that died most likely the 1 hr plus in low salinity?

Is the flow of 530 gph stream pumps too much for the fish and coral in a 30” long tank? Should I be looking for smaller pumps or controlled pumps? What would be a good gph for this tank to start?

I appreciate the fast responses from everyone. Thanks.
 
Sadly I managed to tire to death a few fish with too much flow.
Really? Do you mind explaining a bit as far as how much flow and tank size? Were the fish small? I think I might have done the same and with added water issue it was too much.
 
I always place the bag in the water for 15-20 minutes. Slowly add tank water to the bag. I do this for 30 minutes before adding the fish to the tank.

As far as your wavemakers. I don't think it's a flow issue with that size of your tank. Do you have the wavemakers pointed to the surface? Where do you have them placed?

Yeah, no joke. It was a 330l cube. I had it running just on one circulator pump. I added a second one. Thought it would help with some dino or cyano issue. It criated so much flow that 2 fish died in 2 days. Didn't see any other reason. Both too little and too much flow is bad. The fish need space to rest as well.

I tried a couple of different ways.

1. One on each side pointed to the opposite end. One close to back glass and the other close to front glass. Tried tilted up to surface and also at glass next to them. Moved the up or down on the glass.

2. Tried both on back glass opposite ends pointing towards front glass at various spots and tilted up to surface.

In the end when I ran only one the fish seem to move around the tank a bit more. My rockwork is only about little less than half the tank height.

I’m thinking of going with a smaller pump or controlled pump but either way less gph.
