Re: [APD] My 90 Gall tank

Tom just responded to your first post - with far more authority than I 
have.  My further 2 cents worth is:  You can clean the tank all you 
want, but don't drain out a big percentage of the water when you do it. 
  When you add a big dollop of tap water you may be adding a spike of 
dissolved CO2, and that may trigger the algae.

You can have much more than double the recommended levels of phosphate, 
nitrate, and other fertilizer, without causing algae problems - algae 
is not caused by high fertilizer levels.  Far better to have more than 
needed than to have less or a wildly fluctuating level.  NO3 level to 
aim for, as I recall, is about 20-30 ppm.

If you don't use CO2, don't use super high light level, and add reduced 
amounts of fertilizer only once a week, I don't see why you can't have 
a nice open look like you want.  Just avoid spiking the CO2 level with 
water changes ("condition" water in a container before adding, for 
example) and avoid any ammonia spikes by not over feeding and keeping 
dead leaves and fish cleaned out.

I'm sure others will correct my errors here!
