Floating Particals After Partial Water Exchanges

I set up my 10 gallon aquarium 11 days ago. I cycled without fish for 5 days and the on the sixth day added three Brilliant Rasbora. Twice since then I did partial water changes of about 4.5 liters each time.

The steps I took were
1. I used a gravel cleaner to remove what ever waste I could. I went over the whole bottom.
2. After dumping the bucket I filled it with approximately the same amount of tap water as I removed.
3. I then added 5 ml of Nutrafin Aqua Plus and 5 ml of Nutrafin cycle to the bucket.
4. I poured the bucket as carefully as I could into the aquarium.

When I did that it stirred up a large amount of what I call waste or debris. Would that be common or what am I doing wrong.

I also noticed some white algae on the front glass. Do I such need an algae scrapper to clear it off ever few days.

I am trying to learn the proper way to look after fish with my grandkids and any advice or suggestions will be greatly appreciated.

First of all doing a fishless cycle for 5 days then adding fish is useless ... after 5 days you arent even cycled yet then you add more bio load that could create an ammonia spike and reduce the effectiveness of your bacteria
anyhow the whole point behind fishless cycle if to not hurt the fish... and by ading fish on day 5 its like you added them to an ammonia soup or nitrite. as for algea already that would mean it either has too much light time or sun ligh hitting the aquarium, anyways I would return the fish and continue with the fishless cycle it should take about one month to be complete.

If ammonia is an issue and assuming that the fish aren't going to be returned, you're going to have to do frequent large water changes to keep the ammonia level below .25 ppm if you want your fish to survive long term.

This will slow up the cycle considerably but you'll have fish that are alive and healty at the end of it all.

When adding water back in after water changes, try using a water jug or pitcher and pour it over an ormanent in the tank or use a coffee mug or bowl at the bottom of the tank and pour the water into that instead of directly over the gravel. That will stop from stirring up anything you missed when siphoning.

If you have that much stuff left after siphoning, you might be overfeeding.

Animal testing is a terrible idea; they get all nervous and give the wrong answers.

Partial Water Changes

I added the fish because the man at the Pet Shop said it would be ok. The three fish seem to be ok from what I can tell.

Amonia does not appear to be an issue I've check it twice and it is below .25.

im sorry to tell you this but most animal place will tell you its ok because they wana sell you stuff adding fish in an aquarium that is beginning to cycle is not good even tho ammonia may be less then .25 ppm for now it doesn't mean it will stay this way. here read on aquarium cycle then you may understand what I mean

Brilliant Rasbora don;t seem to be eating

I have three Brilliant Rasbora in my aquarium for over a week now. I feed them Nutrafin Max Flakes twice a day. The last three days they don't react the same as in the beginning when I feed them. at fish as soon as I fed they came and it was actually fun to watch them eat. Now they pay no attention most of the time when I put food in. Should I be concerned?

How are they acting otherwise? Are they swimming as actively as before, or are they more lethargic? Are the gills red? Any remaining near the surface, or even sort of gasping air?

If any of the above applies, coupled with the refusal to eat, it suggests the ammonia and/or nitrite got to them. Another member linked the cycling article previously, that will explain how this works.

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

Thanks for your reply. Other then a change in eating habits yhey seem to be doing great. I've checked the amonia and that is not a problem. I am thinking maybe since they are my firsat fish I might have been over feeding them. I did not feed yesterday and will only feed once a day from here on.
