New 90G high tech planted tank

This is my second tank. started off with a small 4 gallon nano tank which is now a RCS tank. the 90G is a densely planted one with the following specs..
Size: 48"x 24"x 36"
Pressurized CO2 with inline reactor
Substrate: Mix of genesis (something like contro) and ada aquasoil
Filter: Eheim 2217
Lights: 4 T5HO each 54W. two with 6500K, one with 4000K and one with 8000K
Hours: 4 lights - 3 hours, 2 lights - 3 hours
Cycling: done with filter media from old tank added to canister
Parameters: ammonia - 0
Nitrite - 0
Nitrate - 0
pH - 6.4
FIsh: as of now: 3 BN plecos to handle the algae bloom
Planning to add: 24 cardinals, 12 rummy nose, 12 harlequin, 6 ottos, 4 cockatoo cichlids.
Issues: * have got some green hair algae on the christmas moss tied to the driftwood. trying to combat that with cutting down lighting hours and spot treatment with excel. wondering whehther to add some floaters to reduce light intensity.
* Nitrate being zero. Its a new tank so how can it be zero. maybe cos its so densely planted. Shud i start ferts? will monitor serial values and update.
* got some dead spots. planning to add a powerhead to increase circulation. i know one eheim 2217 for a 90G is not enough but due to budget and space constraints i have no other option. maybe an additional HOB in the near future.

It is normal before the tank cycles for nitrate to be at 0. Just to be sure though, if you are using the API test for Nitrate and it is new; make sure to shake the #2 bottle for about 3 minutes before using first time and at least 30 seconds for every test there after. The chemical separates and you will get a 0 reading even after the tank cycles.

I got that information after talking to API because the test kept reading 0 for me. I knew this wasn't right because I was dosing nitrates before my tank cycled.

While my tank cycled, I did dose with nitrate and excel. I discontinued nitrogen after the tank cycled. It is a 72 gallon tank.

thanks for your response. Yes I do know abt shaking the nitrate no#2 solution. Been using it with smaller tank and it's shown positive results then. Anyway nitrate did rise yesterday to somewhere between 0 and 5 ppm. Color was between orange and yellow.
But my green hair algae issues on the Christmas Moss has grown. Been using spot treatment with undiluted excel using syringe (around 0.5 ml ) on each plant while filter was on. It did hit the algae. Cud c it. But while the fluffyness reduced the hairy part is branching out and over growing the Moss. Using 6 hours of light with all four for 3 hrs. Planning to cut down to two lights for the next two days and watch along with Excel treatment. Don't wanna use h2o2 as I don't wanna damage the Moss. If anyone has got any suggestions pls let me know. Attaching some pics of Moss with algae. All other plants r doing fine.

So yesterday after realising that the hairy green algae in my Moss was cladophora I decided it was time for drastic measures before the algae spreadbto other plants. Hence I went in and started removing the Moss. Unfortunately had to remove most of it as it was either dead or entangled with the algae. Finally ended up probably 1/10th of the original Moss volume. Anyway now have tied it to the driftwood like I shud have initially. These r the pics. Will post follow up pics.. if no algae then it was probably the dense clumps of plant which lead to the algae outbreak.

I had the same problem with hair and beard algae on my java moss attached to the driftwood. If I'm not mistaken, miss is a low light plant and when on driftwood it is closer to the light source.

I eventually had to cut back like you did on the moss on top of the driftwood. I ending up planting a dwarf red water lily on the in one of the large crevices of the driftwood. The leaves have grown massively and now block the light and allow the moss to grow on the driftwood.

I don't know if you could do something similar. I do also use Excel 1.5 dose every day but I can't say I saw a huge decrease in algae growth from it.

Hey Rusticdr,

Any updates on you tank? I also have a 48' 90g tank I am struggling with so I am very interested on your experiences and observations.
