Aquarium UV Bulbs

I have recently used medication in my 50 gal freshwater fish tank with one 22 year old comet goldfish in it . the meds cured my fish but must have killed my beneficial Bacteria as now my established tank has been going through another nitrogen cycle. It's been four weeks now the ammonia us back to zero so is nitrite zero BUT my nitrates are now spiked about 80 and the water is cloudy. Did 2 partial water changes over the last 8 days. Will a UV sterilizer help ?? Please advise. Thanks Lina

Hi there. So I am looking into getting a heat dome for my crested gecko. I know they don’t have to have a heat lam but I want him to have a UVB bulb Because it’s good for them. But I am not quite sure that type to get. Any suggestions? I was looking at petco’s tropical combo pack. He lives in a 10 g. With live plant. (I will upgrade when he is bigger) also do you know an age on him? I got him 3 months ago from petsmart. I could tell he was a male a week after I got him. (Pic from yesterday)
