the guy at the fish store said with how bad your tank is u need to use stability put 5 caps in dont change the water cuz at this point ur taking out good bacteria instead bad and just ride it out and hope ur fish dont die there isnt much u can do but bare it and pray they live
Seachem Stability - Product Reviews at The Age of Aquariums - Tropical Fish thats wut im using at the point im going i was doing the water changes 50 percent every 4 days and honestly it didnt help a bit i woke up to a cloud again and again everytime i did that for a month before i went to the fish store today and he gave me this and im not talking abuot a crap store like petsmart or pet supplies plus im talking about a fish store fish only with shark egges stingrays they been around for over 20 years
With all due respect to the guy at the fish store, It is widely known that there is very little good bacteria in the water. What you DO have in your water presently ,if readings are accurate,is high levels of toxins that WILL kill your fish without 50 percent water changes daily until levels are under control .
You recently replaced filter with new one and it is possible that much of the good bacteria you had ,went out with the old filter unless you used some of the filter material from the old whisper filter and placed it in the new filter to help transfer the good bacteria to the new filter.
You also switched to sand substrate and the old substrate also held considerable amount of good bacteria for this bacteria gathers on and sticks to everything in the aquarium, the walls,the substrate,decorations,gravel, and filter.
The cloudiness could be combination of sand that was not rinsed enough before using, which despite manufacturers claims,,,should be done, and possible bacteria bloom.
The nasty smell you report in another thread, is result of waste build up from food and or fish waste that the filter cannot process and can only be removed by vaccuming a small area of the sand with each water change and a different area each time. Sand provides benefit of keeping waste on top of substrate rather than the waste working it's way into the gravel substrate used by many. The sand should be vaccumedfirst and then after vaccuming, you can sift the sand with your fingers or plastic fork, or other tool . To stir the sand BEFORE vaccuming,will result in that waste which we want to remove,,becoming buried in the sand and this could result in rotten smell or nasty smell .
The fish you currently have as they grow (not likely with toxins present) will continue to produce large amounts of waste and it will require frequent servicing of filter to remove those suspended particles that are trapped there and held until filter material is cleaned,and frequent water changes will be needed to keep up with that which passes through the filter material and remains in the tank until you remove it with water changes.
This applys to ALL aquariums ,,but with the load you have in the 55gal it becomes critical.
If you are not willing to listen to those who offer you sound suggestions or advice and try and implement these suggestions,, then indeed ,,perhaps fishes everywhere would be thankful if you ultimately choose not to pursue the hobby.
