White debris floating in tank

HI I have a 45 gallon tank setup for about 4-5 weeks now and recently I've noticed that I have some white debris floating at the bottom and top of my tank. I sift and vacuum the sand about every other day or as needed. And do a water change of about 20% every day. Inside my tank are:
1 log of spider wood
3 Amazon swords
1 micro sword(trying to root it into my driftwood)
2 corys
6neon Terra's
6 rummynose tetras
1 otocinclus

Water parameters are good!
6.8 ph
83 degree water
0 nitrate
0 ammonia

My filtration system is a aquatop cf300
So I'm doing about 5x gph

I was told that I need a bigger filter is that true? Or would a circulation fan towards the bottom help?

 

I think your filter isn't bad, it's at the bare minimum required for a canister filter on your size tank.

Do you know your ammonia reading? It doesn't look from the results given that your tank is cycled.

I would also like to mention that your cories and your otocinclus are going to want more friends of their own kind

Also that your temperature is a little on the high side.

 

I think that nitrite should be 0 but nitrate should be under 20. If nitrates are 0 then I don't think you are cycled.

Can you get a pic? I have clearish white gunk that I think comes from my mystery snails. It vavcums right up. When I water change the first think I do I wipe off the plants and decor so the debris detatches and I can suck it out of the gravel and off the sand (my tank is half sand half gravel) otherwise when I fill the tank back up it will get knocked around and make my clean water look nasty.

Youll still have to vacuum no matter how much filtration you have. I have a hob filter and a sponge filter in both of my aquariums.

Are you doing daily water changes to get rid of the white stuff? Too much water change will mess up your cycle. Idk if 20% daily is too much or not. I do up to 50% twice a week since its a new tank and I still get the whitish stuff.

 

A large water change won't interrupt a cycle. As long as the filter media doesn't dry out it will be fine to do as large a water change as you like!

That's good to know!!
