The old filter does okay. Would like to get another one in the tank. For the mold I have tried limiting the light it gets, and when the GF ended up sick with ick (thanks to my daughter throwing a fish in there without quarantining it first) I put a heater in there while I was treating it for ick and then turned it back down, so it's not warm in there. Since I have limited the light the mold has lightened up but now my plants have died. Since the ick and cleaning the entire tank and throwing everything out and buying new, this is the problem I'm having now. I've never had this in the 9 years having a tank. I take it out scrub it, vacuum the floor and do a 25% water change every week. I bought some erythromycin cause I was told it looked like Cyanobacteria. Thank you for letting me know I've done something good for him! lol It's only one gold fish and I've never had so many problems.

Okay I'll do that. but I could get rid of the air stone I have in there now right? It's just the regular filtration system that came with the tank. It's a 55 gallon tank that I bought at PetSmart 7 years ago. Here's the thing, this gold fish was won at a carnival 9 years maybe even 10 years ago. I had a 1 1/2 gallon tank with a snail in it and just put him in there cause normally they don't live that long, then I ended up with a 10 gallon and now a 55 gallon. I know nothing about fish tanks but I really love them and would like to continue, but I have no idea what I'm doing. lol This poor fish has been through all kinds of illnesses, parasites and has survived, now I'm trying to keep some type of mold from growing in the tank and I'm just frustrated. But I would like a different type of filter in it.

So you just add the air line to the top of the sponge filter? If I get one of these, I can use the stone on the inside and can get rid of the one I have on the bottom. also if i did this sponge filter, I can get rid of the filter system that came with the tank, correct? Thank you so much for all your help and the video.

Thank you so much for the info. I will look for the video. I have an air stone in the tank now hooked to an air pump, could I splice that to the sponge filter up think or would I need two air pumps?

Does anyone have a video I could watch regarding sponge filters? I have a 55 gallon tank and a carnival goldfish I've had for 9 years now, we call him zombie fish. I want to do a sponge filter but not sure how to set them up or size I would need for that size tank. Any help would be wonderful. Thank you!

Thank you so much!!

I did have the heat up cause my daughter bought a new fish and just dumped him in the tank and did not quarantine it, so I had an out break of ich and i forgot about the heat being up and I just turned it back down a couple weeks ago. Maybe that will help. Excess nutrients? What type of nutrients are you referring to? I really appreciate your help and knowledge! This is my first and only fish tank ever, so don’t really know alot about them.

Thank you! So should I try erythromycin? You don’t think it’s the light? Another question, I just put live plants in my tank a couple months ago too, I never had live plants in it before and this started happening around the same time. Would that have anything to do with it? thank you again for the help!

Thank you so much for all your help. It happened again so I took pictures. It just keeps coming back. Your right it’s not mold. So could it be my light is to close? I have never had this problem before, this just started a couple months ago and I’ve had this tank for 7 years. 😞.

The top of my decor and front and back aquarium glass had what was either black algae or black mold on it. My water levels are on point, the best it’s ever been and my temp is right where it should be. It’s a 50 gallon tank. I do 15 to 20% water changes every week cause my zombie fish is a dirty gold fish. Today I took all the decor out cleaned it, did a 50% water change. Why would this be growing in my tank that bad? It was black. The tank is by a couple windows but no direct sunlight to the tank and at night I do turn the light on for a couple hours. The light is a fluorescent bulb, could this cause it and if so what is the best light to use or does it not need light? Thank you for any help! kelly

That blog confirmed! THANK YOU!!!

Thank you so much!! I absolutely love you and your videos and go to them often for information, so funny that you would answer my question. Thank you so much for the response and I will check out the blog and site. The one dose has seemed to help tremendously so fingers crossed it will turn out for the good. Thank you again!

I bought Ich X and have a question. It's says to do a 1/3 water change every 24 hours, I have a 50 gallon tank. So I did a water change, added the Ich x (5ml per 10 gallons - 5 capfuls) now in 24 hours when I do another 1/3 water change, do I just add 1 capful or do I add 5 capfuls again? Thank you for any help you can provide. Kelly
