cloudy tank

i got into the office this morning and noticed my tank is very cloudy. it was fine yesterday. this leads me to a few questions.

1) i know bacteria blooms can do this. but does it do it over night?

2) i feed freeze dried brine shrimp yesterday afternoon for the first time and my fish didn't seem to eat much of it. could that be related?

3)what else causes random cloudiness?

parameters: ammonia 0, nitrite 0 nitrate 20-30, pH 7.6, i don't know my hardness, but i can't see that it would have changed.

weekly water changes: 25% or more every friday, includes vacuuming gravel except near plants (one side).
feed twice a day 4 days a week, once on water change day. alternate pellets and flakes. feed algae wafers evenings 5 days a week. zucchini once a week, starting brine shrimp once a week too.

in the last 2 weeks: i removed the charcoal from the filter, replaced with plan filter material.
rearranged tank, added cave
added rainbow shark

stocking: 2 swordtails, 1 common pleco (5 inch) 1 rainbow shark, 9 tiger barbs
1 planted wisteria, a few java fern, a clump of water sprite (floating)

i know my nitrates are high, i'm trying to get some more plants to help with this, but the lfs in the area didn't have anything worth paying for last time i was in.

Yes it can.

Yes. Not saying this is it, but to answer your question, it may well be related as the (sudden) increase in bioload can affect various bacteria species. This also plays into what I'll mention below, as one more factor that is worse than otherwise because of the other factors, all of which add up.

You have mentioned some issues that can contribute to cloudiness via a bacterial bloom. First thing, I would reduce feeding to once a day max, those listed fish do not need more, and skip a day or two won't hurt (water change day is a good one to miss as the fish should not be fed prior to disrupting their environment). Use both flake and sinking together, no need to alternate these. Nitrates are high, as you said; lowering these should help too. More plants should help stabilize the biological balance, this being out is what usually causes bacterial blooms. Increase wekly water change volume to 40-50% of the tank. There are also some issues with the fish stock. A 5-inch pleco is a big bioload in itself, and this will quickly get much worse as this fish grows (or attempts to grow) to its 18+ inch mature size. It will have difficulties doing so in a 29g tank though, I would consider re-homing him soon.

I commented above on fish. Re plants, Wisteria and Water Sprite are fast growing, and are helping to keep things better than they would otherwise be; esp the floating WS which is a high assimilator of nutrients.

As noted above, this will help. Look for relatively fast growing plants. Pygmy chain sword, common Amazon sword, Corkscrew Vallisneria are some that are easy and fit the bill. If you can get them of course.

i know the pleco is a big bioload and will need a bigger tank, within 6 months he will have one.

other than that, water changes and plants will help? water change is tomorrow; after that it should be clearer?

Cloudiness caused by bacteria will be worsened by water changes. But, to solve the bacteria problem which is a biological imbalance, yes, the water changes and more plants and reduced feeding and fewer fish will all contribute to this, in time.

The good thing is that the cloudiness itself is not detrimental; unsightly, but not detrimental. Unless it worsens, which can cause an ammonia rise. This is explained in my article on bacteria:

(read through the part of the article on blooms, have a small biological background)

so i need to feed less, vacuum the substrate thoroughly, and wait? and monitor my ammonia levels to make sure the good bacteria are still ok? is there anything else i should do, other than remove some of the fish? i am still trying to get some more plants, but don't have all that many options around here and think my area has gotten too cold (highs of 50 F) for shipping to be a great idea.

Be patient. Putting less organics in (less food) and keeping the water better (changes) will help stabilize things. The plants and fewer fish will do this more.

I reset my 115g a couple months back, to replace the gravel with playsand. The cloudiness from the sand cleared in a couple days, but then a bacterial bloom followed. Expected; in a new tank it takes time to establish the biological equilibrium. I just waited it out; weekly 50% water changes (which slightly worsened the cloudiness each time for a day or two of course), fed the fish every day missing water change day. Then literally overnight, after about 5-6 weeks, crystal clear. And has been since. New substrate and thoroughly cleaned (in tap water) filter media meant the re-establishment of the biology. And I had of course trimmed the plants and cleaned them up, so fewer of those. But the 130+ fish had no problems from day one. It just didn't "look" nice to me.

i have a question, byron, following the steps you allready mentioned, would also adding a water polishing pad help. i understand that it wouldnt help the bacteria, but would it help just visibaly

I'm not fond of these things, simply because I prefer to let nature take its course and stabalize; when we attempt to circumvent nature, it does not always turn out for the best. I've not used a polishing pad, but I have doubts it would handle bacterial blooms which I'm fairly sure is what this issue is.
