Do you wash out the filter sponges ?? If you do this could be most of the problem. The bacteria that convert ammonia to nitrite then to nitrate live in those sponges and take 6-8 weeks to establish themselves.

Do frequent water changes - a 2 gallon bucket every day will drop poison levels without causing too much shock to control the ammonia level while the filters re-establish.

Main causes of ammonia are decomposing un-eaten food, decomposing plant matter (includes algae if scraped off and left) and fish urine - so overstocking will not help. One of the problems is that the filter bacteria don't flourish in high ammonia levels .. although they "eat" it .... so the water changes will help the bacteria as well

Drat, beat me to it, As above never wash filter out with fresh water, Always use water from the tank and make sure aquarium floor is clean.

My lava rock now has green alge growing on it and truning the water green, any thoughts.
You would not believe the trouble I am having with this tank.

Do a check also on the composition of the fresh water you use to replenish. If this is too heavily laden with unhelpful chemicals/ purifiers/ heavy metals it makes a hell of a difference to the balance of the tank generally. We used to leave the new water open to the air for a day or two, although I believe it doesn't really take so long to disperse most problem gases.
Don't feed the fish for perhaps a week. It won't do them any harm as a one off, and will give the tank bacteria a chance to get on top of the situation, and for the fish to scavenge any excess food matter.
Don't forget many fish like angel fish just love devouring small fry etc. They can clean them up like a vacuum cleaner. And Guppies are renowned for eating their own offspring.
Good luck.
