Water Turning brown?
I have had a 10 gallon fish tank for the past 2 months. I have had 2 mollies and one platy. The mollies had babies and there are around 30 of them in a little floating breeder. They have been alive for a month. Just recently like past week the water has been turning brown. I cleaned the gravel with a gravel cleaner and changed 80% of the water. I put new water in with conditionor and the next day it was cloudy again and it is getting worse. What is happenning and why is it happening all of a sudden. OH and i have a baby pleco

Do you have driftwood in the tank?

If so, driftwood releases tannins and turns the water a yellow/brown color for a while, it can even start to happen days after adding it. It won't hurt your fish but it doesn't exactly look great. You can eaiter deal with frequent water changes to get rid of tannins or remove the driftwood and let it soak for a few weeks.

If you have no driftwood then I am stumped and I am sure someone else can help you out.

If it is tannin it should have hit sooner. The tank is 2 months old. Also tannin can harm fish as it tends to lower the Ph of the water.
Do you perhaps overfeed? Is there a lot of poop in the tank(on the bottom)? That placo has no place in a 10G tank and if there is a lot of dirt on the sand the pleco might swing his tail and make the gunk on the bottom come up and mess your water. Even if you did clean the sand it might still have gunk in it.
It might also be that your tank is not cycled anymore. Perhaps you washed the filter media with tap water? That is a known killer for the beneficial bacteria in the filter.
What else did you do? Change comething? Any chemicals in the water? Was the filter of for to long?
You need to get a test kit and test the water and post the data. Might help us in finding your problem.
Test Ph, Gh, Kh, NO2, NO3, NH3 and post the data. Do not use the strip testers, get a kit.

After changing 80% of the water your tank is probably cycling again and the cloudy water is a bacterial bloom. As for why it was brown in the first place, I can't say. More information is needed.

80% water change does not necessary mean that the tank is decycled(is that even a word???).
It is not the water that contains the bacteria but the sand, mefia filter, decor.
BUT if you did not dechlorinate the water than you did mess up your cycle.

What are you feeding the fry? A lot of commercial fry food is too fine for a filter to pickup and isn't formulated to not could the water like many adult foods now are. Also, 30 fry plus 2 mollies, a platy, and a pleco is approaching if not well past the load limit for your aquarium and could be contributing to a diatomic algae bloom. Diatomic algae blooms are common in the first few months of tank being set up and usually pass on their own. If it's diatoms there should be brown algae somewhere else in the tank to verify this. If you are using fry food, at one month they should be ready for adult flake and you could switch after the next water change to see if there is a change in the cloudiness.

It is well past by about enough to not be good.

Not every one is prepared for babies ...when some one asks for help it would be nice to be a little nicer...sorry thats my two cents ...I myself have been waiting for driftwood to stop seeping ...maybe there is something wrong with your filter.....have you added any other new things? a baby pleco cool!!!

Mind expanding that? There is nothing in this topic that can be considered not nice, it is just advice and questions that are ment to help.
Also a baby pleco is not cool in a 10G tank. It is about as cool as you living in a prison cell considering you are about as big as a basketball player. Picture that kind of living and imagine that is how that pleco will soon feel.
People need to become a tad less sensitive when it comes to internet answers. There are times when someone does not have the time to play nice and warm and just posts the helpful part and skips the be the nice guy thing to save time for both him and the person he is addressing to.
The OP needs help fast to solve the problem, when i have a problem that needs a fast solution the last thing i need is someone posting 20+ walls of text just to play nice, while i kill time reading his hugs and cuddles my problem is geting no better and i am just wasting time.
Furthermore if you are not ready for babies you should rethink your stock and get only males or only females.
BUT as usual people are very into the whole baby fish thing and only think the whole thing to the point where they have cute little babies. As for what next... it is a question they do not bother to ask BEFORE having those babies... I find it hard to have sympathy for someone who does not think of the well being of live creatures and only sees the "Hey, they are C.U.T.E! zomg zomg zomg so CUUUTE!".
DO excuse my gunshot finesse.
