Water parrameters

Hi everyone.

Bought a 125L fluval roma last week (secondhand)
Im running the same filter and heater that came with it.

When im testing my water, im getting high ammonia, zero nitrites and 30 nitrates.

does this mean my tank has started to cycle again?

We need more information to asnwer you. If this tank was only set up last week, it can't have "cycled" and be doing so again. Perhaps you could explain this.

Second question, have you tested your tap water itself for ammonia, nitrite and nitrate? It is possible that one or more are present, and this is worth knowing not just for cycling purposes but down the road as steps may be needed to deal with it.

Something we all need to remember: The fish you've acquired was quite happy not being owned by you, minding its own business. If you’re going to take it under your wing then you’re responsible for it. Every aspect of its life is under your control, from water quality and temperature to swimming space. [Nathan Hill in PFK]
