Well is it okay to dose Sera Liquid fert?
i forgot the name edi but i think there is only 1 type of Sera liquid fert
i have only those plants which costs from rm1.20-rm5
and also some java moss n riccia in my main aquarium
my ottos n shrimp cant seem to survive
they keep on dying fast
only my SAE survived
but my other fishes have been with me for months
neon tetra, rummy nose, zebras, rasbora, black tetra, cory, white cloud

den i have this nano aquarium which im using to grow riccia
however, the temp goes quite high up coz im using a 16w lighting
its a really small aquarium, can the riccia stand high temp?

my temp in the nano tank can reach up to 32 celcius

I think the sera liquid fertilizer is Florena. Which is quite a good product. You can dose the fertilizer. but don't over dose. follow the instruction on the bottle and figure out how many liter of water do u have.

your otto and shrimp dying due to high temp. (just my guess) coz i hv a shrimp tank and was forgotten to turn off the lighting for 3 days. End up all the shrimps inside there died.

try to get a fan blowing to the nano tank. Riccia can't do well in high temp. They are sensitive to water as well. Try to change 30-50% of water weekly. Higher temp might easily cause the algae problem.
