Slime coat

[Dainese954]

Fishes look pretty healthy but they look dull under a led flash light. How do I get their slime coat back?

[mistahoo]

Use prime, amquel+, or safe during water changes. Promotes slime coat. Dull under a led flashlight could just mean they're stressed.

They look dull because they are stressed.

+1 you should check your water parameters to make sure its okay and posibbly do a water change. what kind of fish do you have? btw

[BeefyG]

Do they look OK with the tank light on? Might just be weak light from the flashlight.

[Dainese954]

I use a half cap of prime during the 20% water changes on a 210g cichlid tank weekly they are eating like crazy. Water parameter seem to be in range. All their fins stick up and they are coloring up nicely just missing that slime coat

[BeefyG]

You could try Stress Coat by API too

I can only see a slime coat on my fish when they're out of water. Fish don't look "slimy" to me when they're in the tank. I have s feeling you're worrying about a non-existent problem here.

When they used to be in the 100 gallon tank the fish looked shiny when I put my Cree led flashlight on them but now they look matte and its only on some of them not all

If the fish are acting normally I'd say take a wait and see approach

Wait, half a cap of Prime? That's only enough to treat about 25 gallons of water. Unless you are pretreating the water before adding it then you need to add enough Prime for the entire tank volume which would be 210 gallons or a little over 4 capfuls. I suggest switching to Safe (powdered form of Prime) which would be a less than a teaspoon for the entire tank. Save the Prime for small tanks.

With safe, a little more than a teaspoon will treat the entire tank. It's 1tsp per 200g. Saves big money if you're constantly doing water changes.

That's what I thought and that's how I dose. I didn't feel like getting up last night so I doublechecked the dose online and Seachem's website says:

Directions for 250 g and larger
To remove…
Chlorine: use 5 g (1 tsp.*) to each 1625 L (450 gallons*) of tap water (removes 4 ppm).
Chloramine: use 5 g (1 tsp.*) to each 1250 L (300 gallons*) of tap water (removes 4 ppm).
Ammonia: use 5 g (1 tsp.*) to each 400 L (100 gallons*) of tap water (removes 4 ppm). Do not overdose!

I checked my bottle of Safe this morning and it does say one tsp per 200g. I'm not sure what's up with their website but a little less than 1 tsp works great for my 185.

[BeefyG]

At half a cap of Prime you're only dechlorinating only about 12% of the new water being added. That varies depending on how close you dose the Prime to where you're filling the tank up but the Prime is going to be diluted throughout the whole tank volume.

[KhmerStyle]

Well he says he does 20% water change so new water is roughly 42 gallons I think 1 cap full should be good imo
