Too much light? Red plants not red? & Green spot Algae

Hello I am having issues with my 55 gallon planted tank... First off I think I have too much light? It's on about 8-10hours. Should I lower my light period?

3x T5HO too much for a 55? Sitting on top of my tank.
I do do ei dosage, and pressurized co2, 3bps drop checker at lime green.
It's pretty heavily planted.. plants look healthy.. the reason I added third T5HO is because I wanted more light distribution, and my glosso was not spreading.. of course I have learn I should trim it more often.

Another thing is I am developing green spot algae on my walls of the tank, along side with some brown stuff that look like diatoms but it has been going on for awhile now. Should i lower my dosing of nitrates?

Also my plants are not red they are all green. healthy but green. Near the top they are turning red. Should this ibe a issue of too much phosphorous? I dose seachem iron, about 10-15ml per week. The only red plant that stays red is red tiger lotus everything else that suppose to go red isn't....

Thanks trying to narrow down the issue here.. I think I might start off with the light??

*edit* I have red pottery clay.. from michaels.. in my substrate but it doesn't seem to help red plants? I see plants rooting to the clay though, when I unroot stuff..

What all do you dose? I do Flourish, Excel, and Trace, at about 2/3 the suggested amounts, 4x54watt T5HO and CO2. I have a BN pleco, 2 SAEs, the odd amano shrimp, and 5 otos (these are the only ones I really need; the others eat dying plants and special food and the shrimp whatever they can get their little things (hand-grabby-pincher-things) on) as algae eaters, and no trace of algae. Well, a little green spot algae does pop up at times, but it gets overpowered by the A-Team and the trillion vals in the tank. My ludwigia's leaf undersides are deep purple. I don't dose nitrate or phosphate/phosphorus. Those come in the package of fish and plant wast.

Oh, and the tank's a 55, too.

I thought green spot algae was an indicator of not enough phosphate, but if you're dosing according to EI guidelines, I'm not sure what to tell you.

I think you can dose more iron than you are currently. I dose twice that amount on my 29.

I want to eventually start dosing something else the seachem is gonna be costly if I do more dosing then I already do.. is there some sort of IRON dry ferts? Besides iron being in CSM+B....

As far as livestock, I have 1 BN pleco, 2 amanos, 2 sae, 6-7 otos, a nerite snail... And a bunch of other fish..

Ahh I am actually getting confused...

I dose

+/- 1/2 tsp KN03 3x a week
+/- 1/8 tsp KH2P04 3x a week
+/- 1/8 (10ml) Trace Elements 3x a week
50% weekly water change
and
15ml of seachem iron

There are dry iron compounds you can use. Any seller of the NPK and trace salts probably carry them.

EI isn't engraved in stone, it is a starting out place. If you aren't happy with the tank or you think you can make improvements then bump one of the powders or liquids up or down a bit for a week and see what you think. I would start with the phosphate, bump it up half again after you polish the GSA off the glass and see what you think after a week.

I don't happen to dose more iron. I tried it for a week and didn't notice any particular change in any plants or algae so I dropped it. I did increase phosphate dosing and noticed a dramatic decrease in GSA on Anubias and the tank walls. Sold on phosphate, don't happen to see a need for iron. At the moment......... A different tank would have different needs.

Keep notes! If you can take photos too.

If you look at the PAR charts in the light section, it seems to me you have very high light. I have a 60g and was running 4 54W t5ho lamps and quickly had all kinds of algae - diatoms, green spot mostly. Many folks in this forum suggested I reduce light and increase c02. I now use only 2 of the 4 bulbs plus I have a screen between the lights and tank. The lights are 4 inches above the tank and are only on for 8 hours. I also have some ricia and now densa floating on to cut it down even more. Long story short, my algae is going away. I still have some and my tank is only 7 weeks old but it is better when i reduced the light and increased co2

*60g
*Substrate = 50% Florite sand 50% regular Florite
*Lighting 108W of a 216W T5HO Aquatic Life hood 25" from substrate 8.5 hours daily.

I advice you to find out about dry ferts they are waaaaaay cheaper. Like 30 bucks every 2-3 years!(for me)

I have found that GSA in my tank is related to lack of co2. That is my experience.

A heavily planted shrimp tank is possible!

Thanks everyone...

My new plan is taking out 1 T5HO.
Can't increase my co2 anymore if I do the drop checker becomes yellow.. So I will leave the co2 diffused thru a ceramic diffuser directly under a powerhead. I will also increase the phosphate dosing...

I scrubbed alot of the GSA off the glass... I will update this in a week or two to see if this helps!

One thing at a time :P hehe...

I agree with Dmckmc. Depending on the reflector, you may be able to do fine with just one of those lights. Two might give you better light spread, especially if you can suspend them over the tank. Less light is often the key to most algae problems. HTH.

I've got horrible green spot algae, and I only run 56 watts of t5 normal output on my 75 gallon. Reducing your light may not be the trick
