High Tech 75g Help

Here is the setup and numbers for everything I could think of pertaining to this subject

Tank size = 75g
gh = 143.2 ppm (8 drops with API test kit)
kh = 7
CO2 = 1 bubble / 1.5 sec
pH = 7.2
nitrate = 15ppm
lighting = 2x 54watt T5 HO
1 x 10k
1 x 5k
photoperiod = 8 hours
Fertz = 15ml/day of aquarium fertilizers micro/macro mix (contains 1 part each of Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Plantex CSM+B.)
Water Changes = 2x 25% week due to my discus

Temp = 82-84 degrees during extremes of day but usually around 83
EXT5000 reactor
Canister filter + powerhead + airstone at night

Plants = amazon sword, melon sword, saggitaria, leopard vals, multiple species of crypts, and anubias nana.

SO here is the dilemma..
-I'm not seeing any pearling (except on algae close to the lights lol stupid!)
-not getting fast growth
-I am getting the bright green algae on the glass and hair algae on other plants

I moved from my old place that had extremely soft water to this place with MUCH harder water, things were growing well at the previous place i lived but ever since the move (nov 1st), I've been having a major issue with getting things balanced again.

Please let me know what you would suggest! Thanks again everyone!

partial ro water mixed in
more co2
whats your phosphate ppm
ive had success lowering my phosphate and upping my magnesium for green dust algae
how ever magnesium will raise your gh which is high anyways

Thanks for the reply so fast

Ill have to invest in an RO unit sometime soon, but ill increase my CO2 gradually.

I don't have a test kit for phosphates either. I think ill ask for one for Xmas lol

No clue but I can find out by tomorrow.

Its crazy, my pH at my old place was 7.8 out of the tap but extremely soft. I was doing about 1bp/1.5s there and it would shoot the pH down to about 6.8.

Here it comes out of the tap at about 7.3 and doing 1bp/1.5s and it goes to 7.2..

Back to basics. What specific light do you have? If it is a Tek light, for example, you have very high light, but if it is a FishNeedIt light you have low light. (Assuming the light sits on top of the tank.)

Assuming you have a good light, you badly need to dose a complete menu of nutrients, NPK and trace elements, and you need good high CO2. You have neither now. (No phosphates, very little CO2).

Your plants are all able to do very well with low light, especially with some CO2.

When you see algae, the first thing to look at is how much light you have.

Thanks for the input!

I have a 4x54 watt T5 HO setup, but i only use 2 bulbs with 10k and 5k spectrum. It just sits on the pegs above the tank.

Is my micro/macro mixture from aquariumfertilizer.com completely insufficient on what i need? It contains 1 part each of Potassium Nitrate, Potassium Sulfate, Magnesium Sulfate, Plantex CSM+B.

What else should i get for the tank and any advice on how to calculate the amounts for those? Ill probably buy dry fertz and make my own mixture (its been more cost efficient so far)
