i built a canopy for my 180 awhile back
on the outside i stained the lumber and on the inside i used a white high gloss kitchen paint,

so every couple of weeks i pull it down to clean it and ive been clean some blackish mold off lately

is this normal... is there an issue for fish health here,
the mold is very minor thin/nonraised and only in a couple of areas,

do you think i should repaint the inside with a mold resistant paint?

what kind would you think i should use?

i woulda though kitchen/bath paint would resist mold but i guess not

any way let me know if im just being over cautious

any thoughts?
 
I'm in the same boat. I used that white rubberized roof coating that is mold and mildew resistant. I remove golf ball sized fungal growths weekly from one end. :nilly:

I think I shot myself in the foot, because I think I can only use more rubberized roof coating over it. I'm thinking the best solution will be an outdoor oil based paint. You can get a funguscide/mildew additive at the paint counter at HD and Lowes, but I think "outdoor" paint already has it. Oil based paints are about the most weather resistant paints you can get.
 
I cleaned this off either Sunday or Monday, and it is now a tad larger than a quarter.

This is the inside. This is the back corner and goes all the way around to the front. I also cleaned it from the inside Sunday or Monday (it was a freaking forest in there).

Line it with polished stainless steel or aluminum foil tape. No more mold and both offer a BRIGHT finish that reflects very well.
 
Damn, that was too simple...and I have some stainless tape too. Why didn't I think of that. :screwy:

That will be an excellent "quick fix" but I still have to take the hood off and do it right. The mycellia (sp.) has to be deep into the wood and is eating my canopy from the inside out. :nilly:
 
Wash it with a bleach solution, let sit, rinse well, let dry,scuff the surface with a scotchbrite pad or sandpaper, wipe clean, and stick it to it!
 
That's my 250g hood. If it was one of the smaller tanks, it would already be done. :( Getting help to take it off and put it back on is what is holding it up.
 
Ya gotta do what ya gotta do.

The hood isn't in the water. The rest is all about concentrations and percentages. Any splashes that may drip back are going to be so minute in volume that they won't be able to carry back anything in enough quantities to be concerned about.

If you were to assume significant leaching, water changes would be your forgiveness. The water volume back to the tank from splashes would be so small that if water changes were not regular, the levels of toxins would still be insignificant. Calculate the ratio of one drop of pure whatever to the volume of the tank to get an idea of what we are dealing with. When you medicate a fish, you put it into a quarantine tank so you can concentrate the dosage to have an effect. Splashes would never be an effective means to dissolve medication and to get it into the tank. Where medications are intended to be soluble, paint is not. Fungicides/mildewcides are not soluble either. Otherwise they would wash away outdoors when exposed to rain and would no longer be effective. They are effective after years of exposure and there isn't a renewable supply.
