Aquarium Advice Regular
So Friday I get home from work and all my fish are dead(I have had them for about 5 months). I tested my water Saturday and everything came up normal, so I figured it was alright to replace what I lost a little at a time. I added a lawn mower blenny Saturday to just test the waters first hand and see how he'd do since I was still a little reluctant to put anything else in since I had just lost everything. Well I wake up this morning and the blenny is dead. I saw him last night and his gills were moving very fast like he was breathing really hard and he came up and hit the surface a few times. This leads me to believe there's a lack of oxygen in the tank but I don't see how that's possible as I have water moving in my sump which no doubt would aerate my tank. So my question is just what do you guys think is the matter? I really havn't been able to come up with anything since I tested my water and everything came up negative. I have some micro-algae growing next to my spray bar and it seems to be turning dark green and stiff looking(it was light green and very wavy before) the closer you get to the spray bar almost like something coming out of the spray bar is hurting it. I don't know if that has anything to do with my big problem but just another piece of evidence. I also have somewhat of a green hair algae problem growing on my walls and live rock could that be suffocating fish? How much is needed before the hair algae starts killing things? Because I don't think I have nearly enough to suffocate my fish. Well any help is greatly appreciated on what yall think is wrong, and I will listen to anything haha this is driving me nuts.
