Oxygen in tank?

[Zbutcher]

Hey everyone,

I kinda have a weird question so my AIO 25 gallon saltwater tank has a sump system in the back of it, 3 chamber. As the water flows into the last chamber it agitates the water a bit and air bubbles get sucked into the impeller of pump and tiny air bubbles get pushed into the tank.

I was curious, i know dissolved oxygen is good but is there a risk of TOO much dissolved oxygen? How do you even regulate that?

Thanks.

I also have a weird issue with snails where every time i put them in they instantly close up and dont move for days on end then eventually die. My parameters are perfect. I even took the water to my LFS for testing. I have finished my cycle i am in a diatom bloom hence why i bought the snails. Someone mentioned it could be metal from the old pipes in the house. So i did a 20% water change with RO water from safeway and also added in some Rid-Metal from kordon just in case. Does anyone have any ideas? There are other animals in the tank. I have 2 growing baby clownfish that are eating and swimming well. I have 2 nassarius snails that i dont see much they just go under the sand but everytime i do find them they are alive. I have 1 hermit thats fine and 1 emerald crab.

Thanks.

The bubbles can irritate soft corals so you can try raising your water level a tad or if you are crafty you can try and silicone in a bubble trap. The model/tank name can help if someone has been through this before.

Your diatoms could be dinos (pic would help) as they are toxic. Nitrate levels could be high or significantly different from your LFS. Snails love dying on me too.

Thanks for the reply! So thank tank is custom made its 18x18x18 though if that helps haha. But maybe if i put a sponge laying flat against where the water comes in that would help. So with the water jet should i have it creating a bit of a wave on the surface foe dissolved oxygen?

Its nor dinos i know that for sure. Its more brown film algae. But yeah its weird all my levels check out. I literally have no idea. Im almost tempted to by established water from a tank. Empty out mine and use theirs and keep my biological media the same. I cannot think of anything else.

Inverts are more sensitive to parameter swings. How do you acclimate them? Humor me... what is your late nitrate reading?

Sponge would likely help as well but may cut down on the flow a bit. Return jet optimization will vary tank to tank. On my evo I have a flat nozzle skimming length wise down the tank and a Random Flow Generator nozzle diagonal to other corner and about 15 degrees below. Having them aimed at the top helps if you have other flow generators and helps with air exchange.

Nitrate reading is 0. I acclimate them by floating them for a good half hour. The add a little water to the bag. Wait another half hour. Add a bit more. Rinse and repeat until there is more water from my tank than the LFS.

Ah its cool i just topped it off with some left over saltwater from my water change. Yeah since mine is a custom tank i jerry rigged the return jet. I can't find the attachment that screws onto it for a gooseneck nozzle, no where locally has anything like that, maybe amazon but idk what to search for or the size.

I would try and make the nitrate non-zero but should contribute to snails dying...

Last idea on the snail death thing..
How warm is your tank? What types of snails are you getting and having die? I remember reading a while back that some types of snails only thrive in cooler waters on the lower end of reef tank temp ranges.

Yeah i didnt think a low or 0 nitrate level would cause death.

Temp is 79-80 might fluctuate between the two but yeah. They are turbo and trochus and astrea which should be fine in those temps. I am quite literally stumped.

I bet its the algae.
Your particular strain is most likely poisonous to them. why who knows.

Or somehow something got into the tank transferred in by a hand, spill, or something that you may not have been aware of and wont be detected with water column test kits.

Let me ask this, as I re-read your original post.
When you say put them in...

Do you mean as soon as they touch the water the retract and shrivel, or do you mean in an hour or two you find them like this?

If its immediate then not the algae.

More just they touch the surface and close up.

Yes then there is something in the water column then.
Now its time to become Sherlock Holmes.
The regular regiment of water column tests will not find the substance.
It could be the existing snails have grown a tolerance to what ever it is as it may have slowly increased over time and for the new guys its lethal.

I suggest doing an ICP test, this may reveal the problem as it will tell you a lot more about your water column.

Wouldn't a large WC and running carbon eliminate such toxins?

Do they close up during the acclimation or just when placed into the tank? If you were to place one in a cup of the water and they don't close up I would lean toward stray current in the tank.

If the water the OP is using has the issue then no, as your just reintroducing the containment, at potentially greater volume if the source is increasing.
Need to know what it is the OP is dealing with first.

You have to ask what will instantly kill a snail?
Sounds like its a reaction that a garden snail has to salt.

Carbon would help but is not an instant fix, as it takes time to strip the stuff from the water column.
Could be contaminated box of salt or dosing additive, or a complete unknown that you would not even think of like changing the soap one washes their hands with.

Honestly i think my beat bet would be to just grab some ro water from safeway

It is definitely when i put them. They are fine in the acclimation process

 

[K7BMG]

Strange situation for sure, wish I could be more helpful.

Stray current could be it as well as NeonRabbit221B stated.

 

[NeonRabbit221B]

Grab yourself a multimeter and check for voltage in the tank.

If you don't have a GFCI and ground probe it would be wise to add those.
