Recently I set up a 32gal fresh water tank. I do have about 24 small
fishes including the rasboras, danios, barbs, tetras and couple of
live bearers and an angel fish. I have four small plants there. The
tank is filtered with RENA submerged filter 600L/h, and have two 61cm,
20watt full spectrum fluorescent lights(10-13hrs/day switched on).
My question is I am seeing small green spots on my sides of tank and
the water turns a little bit green even with partial water changes.
My white gravel is also changing to green spots color( looks like
rust) .Please any advice fellows? Solon
- If you have 24 fish in your 32gal that is too many fish. Angel fish
get to be about 5-6 inches alone. If I multiply 2" of fish times 24
I get 48 inches of fish. That doesn't include the larger angel and
possibly sword? livebearer. This inch rule can be pushed a little
if you had ALL neon tetras, but with your larger fish you definitely
went over the limit. Also with all that light and nutrients and only
small four plants I would expect an algae bloom. What kind of plants
are they? 10-13 hrs seems a lot for only 4 small plants. Jeff can
advise on the lighting requirements since he is the plant guy. Make
sure you aren't adding phosphate to the tank in any chemical form
and try to reduce the number of fish.
- Green,green,green...water...old problem lots of ideas and methods....first
take into consideration the stuff Joyce told you.. The green spots
on your tank are normal just scrub them off...as for the green water
algae kinda bloom...usually caused by excess nutrients and too much
light?....First drop down your nutrient levels and do a 50% water
change....starving your tank from light will work if you turn off
your lights and duct tape a blanket over it for about 4-5 days....choice
2..get daphnia...if you don't want them free in your tank you can
drop them in a net style breeders trap then remove them after...choice
3 get a diatom filter like vortex or UV sterilizer...lastly the bad
old chemicals like Acurel/F...but I always think about causes first
then treatment....after it's all done drop your light time to 8hrs
per day...if you want to talk plants we can revisit that topic later...have
