Chocolate Cichlids babies, planaria and other problem

Question
I have a 55 gallon tank with: 5 smaller african peacocks, 1 pacu about 4", 1 ghost knife 6", 1 dinosaur eel 6", and 2 Chocolate Cichlids.  Tank has been set up since 4/14/07. Tank Temperature - 80.  The Chocolate Cichlids started to mate about a week or 2 ago, so I added a tank separator giving them about 1/3 of the tank to themselves.  The babies hatched (about 60 of them) 3 days ago.  Started swimming yesterday.  I noticed about the 3 days ago I had planaria (the stringy worms).  I also noticed a white fuzzy film on all the plants.  So I cut feeding in half and did a partial water change.  I currently feed about 16 peas without shells (making sure every fish get some - the pacu more than others), and one brine shrimp.  The planaria hasn't gotten any better, but I don't want to cut feeding back too much and kill the babies. How much can I cut back and still be safe?  Also, when I woke up this morning the female chocolate has the white fuzzy film on her tail.  Is this related to the planaria?  Should I remove the parents and children to a 10 gallon tank?  Water test today(pH - 7.0, Nitrate - 15, Nitrite - 0, Ammonia - 0).

Answer
Hi Kerry,
 It sounds to me like you need to do more water changes. You should be changing about 25% of the water once a week, every week to keep the tank healthy.

 If it were my tank, I would change 25% of the water today, then again for the next few days to get things back to a healthy state and then get on the once a week schedule.
