so i am not sure where this topic falls admins can move it if they wish.
but tomorrow i am doing a water change on three of my tanks and possible the th one instead of switching the days like always buuuuuut i think i have an algea problem in three tanks.
when i went to go put new fish products away after buying the supplies i was running low on i noticed in the guppy aquarium i was getting more algea than normal.three decorations in the tank lok like a dark brown like as if the were caught on fire but all the decorations aren't near the heater but i know it's algea cause i went to clean the feeding ring last week and this week it has algea on it again. doesn't seem to bother the fish but it' concerns me.this was in a 10 gallon tank
in my male betta's tank it has algea but it's green and looks gooey kinda looking just sitting there like web around the decoration this is in a 5 gallon tank
in the female betta tank hers is the same as the 10 gallon tank all brownish looking and such and she is in a 2,5 gallon tank
i have a 4th tank another 5 gallon tank with another male betta but his tank is perfectly fine no alge anywhere that i can see but it's just my three other tanks
readings seem fine.
i keep up on my water changes which is once to twice a week.
i clean the filters and pumps and i clean the rocks and decorations
so where is this algea coming from
all 4 tanks i know for a fact are cycled
i have moss balls in all four tanks. 2 in the 10gallon. and i want to add this live plant i bought today in one 5 gallon tank as a test to see if i like it and get more for my other tanks but i don't want it to get kiled if the algea is gonna murder the poor thing.
what should i do other than the logical clean the decortions.i want to know how bad it is and what to do
i have never had this problem before i've had 3 tanks for 9 months now one for about 4 months
