I seem to have a problem with Ph. :cry: Is it true that coral well cause your Ph to go high, and if so what do I do? Get rid of the coral all at once or do it gradually?
 
Generally the ideal tank pH is that which matches you tap water's pH. This is unless it is on the extreme high or low end of the scale. Some fish have requirement also.

Please give us a little more info on your tank.
 
My tank is a truvu 55gal with two compartments and two tubes conecting the two compartments. My Ph is about 8.4. I had 4 Giant danios, 2 bristle nose plecostamus, 2 young angel fish, 3 glofish and 2 corydoras. 350 magnum filter & under gravel filter with 2 power heads. White coral substate and a few fake plants and some fake logs and a few real rocks. I have a 4' shop light with 2 T8 bulbs heater set at 76. Not sure what else you need to know! The fish are dying off pretty fast; all that are left are the Danios, Angels and 1 Corydora... I seem to have a lot of a brown algee. is this due to a high nitrogen content or high Ph? I have lowered the amount of air I was putting in, by turning down the power heads. thinking this well help slow down or stop the brown algee.. Any suggestions greatly appreciated. Thank you dowheart
 
Well it does raise your pH. I don't know how much coral you have but maybe you could remove some of it. If you really like it.
 
The coral is why your ph is so high... Ammonia is extremely toxic at 8.4 ph, that might explain your health issues as well.

Yep, the lower the pH the less toxic ammonia. Seems like the OP has a double whammy of bad luck = uncycled tank (ammonia) and a high pH which causes the ammonia to be even more toxic. Remove the coral gradually.
 
Is your tank cycled, how long has it been set up?
What are ammonia,nitrite and nitrate levels?
What is the pH of your tap water, and the pH after your tap water has set for 24 hours?
