Algae Died

[Ratankun]

Hello All

I have a 15G tank which contains plastic plants. The tank is around 6 months old and contains 9 Harl Rasbora, 1 Betta, 2 snails and some amano shrimp.

The tank used to have a lot of green algae growth, too much for my liking. During water changes i used to remove a lot of it but within a week it was back. Since the last clean 8 days ago, not only has it not grown back but remaining algae seems to be dying.

Any ideas on what could cause this? Nothing in my tank has changed including light hours.

thanks

How long has the tank been set up?

6 months

Well, it is my personal belief that algae dies off when the microbial assemblage reaches full maturity. 6 months could be around this time. I don’t believe there’s any magic to it. Just patience.

Yes. A lot of the algae in a newer tank is generally blamed on the nutrient imbalance and lack of other beneficial bacteria that will compete for the nutrients

So, typically the issue sorts itself out as the tank matures! or for those that don’t like swamp water, it can be managed by uv sterilizers, reducing feeding, light and even completely covering the tank in darkness for several days.

If you haven’t done anything crazy like add a bunch of chlorinated water to the tank, I’d say chances are the tank has just started to balance out itself and the algae is losing the battle.

thanks for the replies, sounds like its just the natural lifecycle of a tank.
