Mike

Hello everybody. My name is Mike and although I have been haunting your forum for the past two months, this is my first post..

I have been keeping fish and relatively low maintence plant tanks for years, but as of three or four months ago have finally splurged on Power Compact lights, CO2 tank and regulator and flourite substrates.. And I must say, thanks to all the info on this forum, I have had pretty good results
(thx everybody..)

Now I am moving into a new dimension with the ferts aspect..and I am a bit overwhelmed.. (EI, PPS, PMDD, etc.)

I bought some dry chemicals from Greg Watson's site about two weeks ago.. but I am not sure how to dose this stuff so I was wondering if you guys could take a look at my parameters and give some advice..

Tank: 90 gallon
Lights: 4 x 65w power compact
Substrate: Flourite

PH: 6.4
co2: 35 ppm
KH: 4.0
GH: 260 (very high, huh?)
Phosphates: 4.0 - 5.0 (also very high..)
Nitrite: 0
Ammonia: 0
Nitrate: 25-30 ppm

Note: All in all this tank looks pretty good..(i'll post a photo later..) but I am getting a bit of algae on rubin sword and some dwarf sag...crypts, vals, rotala rotundiflora are unbelievable..

A couple weeks a go, dwary sag leaves got sorta transparent so I added micros (CSM+B from Watson's) and now they look fine..

Mostly I am concerned with high Phosphates and Gh.. And I have no clue as to how to mix/dose the dry chemicals (KNO3 - KH2PO4 and K2SO4 )

Thanks in advance,

Mike
