I have about 35 OEBT shrimp in a 20L (prob holding 15 gallons of h2o)with a air powered sponge filter and a fluval 20, sponge on the intake.
for plants I have a bunch of moss and a good 20-40% of the surface covered in floaters.
I add no ferts except a 'dash' of potassium every two weeks when I change about a gallon of water.
every mon-wed-fri the shrimp get about 2-3 flakes of fish food.
I top off only with RO water.
On the fluval20 I only use the sponge inserts.
So far, I have had zero deaths I have a few saddled females and I have one berried.
20 shimps have been in the tank about 5 weeks. 15 in the tank for about 2 weeks.
How often should I clean my filters? I have been taking the 'keep your hands out of the tank' approach so far and I'm happy with that.
I was thinking to just clean the sponge after 3 months, the HOB 3 months after cleaning the sponge, then the sponge in another 3 months.
-you get the idea.
FYI all my parameters are fine and filters fully cycled, nitrate reads zero or it is so close I cant tell the difference.
any feedback would be appreciated.
