Test your water daily. Im assuming this tank isn't cycled? If you see signs of ammo or nitrates especially, change out enough water so that your levels of ammo is 0 and nitrates are 10.

Once the tank cycles your bioload and filtration will determine when and how much water is need to be exchanged to keep the nitrates in check. I tend to overstock the majority of my tanks but also over filter them, so in my case weekly water changes of 50-60% keep my nitrates below 20ppm. If your understocked a smaller change might be acceptable. Check your water parameters weekly after your cycle to determine your schedule.

Yep, me too hukit. Two of my three tanks are overstocked, but like you are overfiltered and I also do at least 50% w/c's weekly. Keeps 'em healthy.
