[anew2thereef]

Guys,


I have a 40 gallon tank, and it seems that my corals are dying... I do not have a skimmer on the tank and it has been running for about 6 months now. Corals in the tank are

Hammer
Torch
Zoa
Leather
Galaxea
Trumpet
War

Water parameters are...

Alkalinity 5.8 Dkh
Phosphate 0.81 ppm
Sanilty 1.22

Get your alk up to 8-9 salinity up to 1.25 and po4 down to .05

Do this slowly.

How often do you do water changes? I would do them more often to replenish alk and trace elements.

Yes I would start with some smaller water changes to bring the chemistry closer to NSW/normal saltwater values. The link below provides those values.

I do about a weekly water change to the tank every Monday about 5 gallons sometimes more... I use rodi water
Any suggestions would be greatly appreciated

What kind of salt mix you using? I use Red Sea blue bucket and new salt water at 1.026 mixes to a alk of 6.2 ish! So I raise it to 8.5. Your alk is real low and phosphate higher than it should be. Raise the alk .5 a day or when you do water changes dose the new water to the higher alk and raise it like that

I'm using Tropic Marin Salt, when I do mix it comes to about 1.25... I hear adding some baking soda will help rise the alk is this true? But adding it to a 5 gallon bucket how would I gauge that? With phosphate I'm doing a weekly water change to drop it down the best way I can but seems to be a very slow process any recommendations would be great!!!

Thanks,

Bulk reef supply has aquarium calculators for dosing baking soda. Ive done it before and it worked like a charm! Give it a google, its easy to find (unsure about link rules here)
