Why is my breeding tank for gouramis all dirty on top???? Ten points for best answer!!!

Question

I am breeding gouramis, first time, and I did al the stuff a reliable web site said, but when i looked in it today, the top of it had like dirt looking stuff and the filter was on. I just spotted the bubble nest next to my floating plants on the opposite side of the filter of the tank. I now unplugged the filter so it doesn't bother the bubbles and soon to be eggs!! yay!!! Can this scum be because of the bubble nest?? Could it be from the pH lowerer I just put in the tank at around 5 o' clock central time zone. Could you tell me what it might be please??? Also, will it effect the fry and bubbles and eggs??? Will it effect my parents, but mostly my male since I will soon be removing the female???? Answer all the questions please and leave a source if possible!!!! THANK YOU!!!!

Answer 1

the dirt on top of the tank is most likely from the bubble nest. nothing to worry about just scoop the dirt out with a net. but after a day or two it may happen again but again nothing to worry about just scoop the dirt out again.                 hope this helps!

Answer 2

what it is on the top is just a little bit of bacteria residue started up there, and then the bubbler sends tiny drops of water up there when the bubbles at the top pop, and it rapidly spreads. it kinda sux, i know because it looks nasty. i would just move the bubbler somewhere away from the edge, so not as much little water droplets splash up there and give you more of that nasty scum.as for the male chasing the female, not for this to sound creepy, but the male is a little "frisky" and wants to exercise his pleasures on the female, but she doesnt want to give herself up to him right away, and so they chase for a while, no more than a day, then they mate, and you get more gouramis!!! best answer plz, good luck breeding! : )
