thanks, tanks has been running for a year or more.
inhabitants are 2 8 inch arowanas , 11 pcs silver dollar 3 inches.
3 small plecos and a pir of green severums.
tank is a 300 gallon 8x2x2ft tank.
filtration is 4 ft overhead filter with 15 gallon sump tank and 3 internal power filters.
the tank is outdoors and recieves morning sunlight. but no algae problems.
its a bare buttom tank so its easier to clean with 2 pcs huge driftwoods.
i sometimes notice cloudiness even with my other tanks.
out tapwater is chlrinated , but i use a dechlorinator .
after a few hours thetank clears up again.
but i've noticed before when changing more than 50 % water , there seems to be slime or wgite stuff buildup on the glasses , what could be the cause?
