Can I clean filter during cycling?
Hi I am a novice. 204L AquaOne tank - 2nd hand tank but all the filters were cleaned with tap water before I purchased. Doing a fishless cycle - have some plants and have an airstone working. Using Prime and now Stability - initially I was using a prawn but now using a pinch of fish food daily. Water tests shows that it is cycling - I hope. Readings now 0 Ammonia 0 Nitrite 40 Nitrate. Ammonia only went up to 2 and Nitrites have been 0. Can I clean the filters (in tank water). Did a 50% water change 2 days ago as nitrates were 40. Substrate is Amazonia and at same time as 50% water change I removed some driftwood as PH was very low and thought this may be the reason - the water became very dirty. I thought it was an algea bloom it does looks cloudy when the lights are on but when I changed 10% of water today it was brown - unsure if it is it an algea bloom or just dirt churned up. Has been cloudy for 2 days now. My concern is the filters are too dirty to clean this up. Has been cycling for 3 weeks now and I haven't touched the filters. My query is should I clean the filters or will this slow things down. I think it is OK to leave the light on while it is cycling but is this still OK if this is an algea bloom. Steep learning curve and any advice would be most welcomed.
