I left from my city for a ~1.5 month , for health problems, in family.
A friend care the tanks , only food every 3-4 days.
The 180lt tank was without co2 and ferts.
I dont loose any of plants in this tank, but clado and bba grow.
Shrimp tanks, when i leave there was 2-3 of float plants, and when i came , it was a night mare..
Loose a lot of plants, rotala mac, tonina, and erios, but pantanal , grow out of the tank.
But i found alive all my shrimps .
After one week the 180lt , cleaning filters , substrate, water changes.,add co2 and some ferts.
In shimp tanks i left only the healty plants and they grow slowly..
