Hi this is my first post so please be gentle
please help i had my 220litres tropical tank running cycling for 7 weeks before i put any fish in started adding fish steadily and after 2 months all was ok ph between 7 and 7.5 no ammonia , no nitite and no nitrate.
1 month later all is going wrong my ph dropped to 6.5 i added bicabonate of soda and now seems stable again all other readings was 0 except nitrae which was about 20 ppm ,i thought it may be because i over fed so i didnt feed them for 3 days and now its very high 50-110 ppm probably near the top and i dont know what to do was going to change the water tomorrow but unsure i changed 25-30% 2 weeks ago i use ro water.no new fish for 3 weeks plec and large gourami were the last added
my filter is an xp3 i wash my sponges out using the water in the filter i have ceramic rings and the black balls in there do i need to wash these in tap water to clean them as i only washt hem in the filter water
the fish are 1 large silver shark 6 " long,1 large pleck 10" long,1 opaline gourami 2-3"long 1 moonlight gourami 3-4"long,3 sailfin mollies 2"long (1 male 2 females),3 flying foxes 3"long,2 large snakeskin goramis 5"long 1 small snakeskin gourami 2"long i have lots of air with 2 outlets the plec clears algee for me 8 real plants (not sure what they are but been in before fish went in) 2 pieces of bog wood which had been in a show tank for 3 yrs 1 300 rena heater jewel rock background with the back of the tank covered with cardboard to prevent algee and gravel.
