Foam on water surface
My friend has asked me for help on a problem with foam on the surface. I am perplexed. She claims nothing has been added such as dechlorinators or anything to buffer. I'm at a loss for info as i do not have water parameters to provide. this is what i can tell you
low tech standard florescent all purpose type bulb
been cycled for a 3 or 4 weeks
PFS for substrate.
hob filter, best guess marineland 125
lightly stocked - 2 rasboras
tap water, guess 7.5 to 8.0 ph
hardness who knows
water level is topped off properly
The foam, and i'm not exaggerating, looks like she has got dish soap on it and ready to wash dishes. she can net it out and it will be fine for a few hours then slowly starts building back up. My wife and i have a waterfall/fountain in the yard and we treat it with an algaecide. if over dosed, and she has, it will foam like that. My friend claims nothing has been introduced in to the tank such as that. i did however slip her some florapride. Can that fertilizer cause foaming if over dosed ? i used that very bottle in a pinch and dosed properly and never had any issues,
I know i'm not giving you all enough info and i apologize but i would still like some input from a generalized stand point.
