Too Heavilyplanted? And "murky" Water

Hello All,
My first post and I'm relatively new to planted tanks. I have what might seem an odd question. Is it possible to have a tank too heavily planted? I have a 29 (us gal) tank with about 30-32 plants (I love plants as much as I love fish...lol). A few of the plants I have are Filigree Foxtail, Temple Plant, Narrowleaf Ludwigia, Peruvian Ludwigia, Rotala indica, Pygmy Grass, Glossostigma, Elodea and a few aquarium bulbs bought at the local Wal-Mart.
My paramaters and eqipment are...
29 US Gal
Coralife 65w lamp and a 20w aquarium lamp (came with tank)
2 Nutrafin co2 kits
Whisper Power Filter 30
Whisper Power Filter 40
water temp = 78
PH = 7.25
Ammonia = 0
Nitrites = 0
Nitrates = 5 (did a 50% water change today...usually read 20)
GH = 9
KH = 14
CO2 = 23 during day and 40 at night (I run 2 air stones all day long)

all of my fish appear healthy and the plants are doing well (some a little too well) lol The fish I have are 1 Pleco, 1 Otto, 1 Cory, 3 Pristella Tetras, 3 Glowlight Tetras, 2 Zebra Danios and 5 Neon Tetras.

Everything had been great until about a week ago. My water is cloudy. Due to this I recently changed both of my filters (I even added the old charcoal with the new to keep the bacteria in place). I did A 25% water change two days ago and I did an almost 50% change today. I'm very good about water changes. I believe I was over feeding the fish so now I am only feeding them every other day or so. Any ideas/suggestions to help me uncover my water condition? I turned off the 2 light timers I have tonight (I figured I'd have a 2 day black-out phase to see if that helps). Any advice is appreciated. Sorry this wound up so long. I added an early pic of the tank "before" the cloudy water. Many more plants now.

welcome to the fish forums !!!

was your question on overplanting a planted tank ?? well for me personally i can get overboard if you cant see to much anymore and also IMHO more plants coupled with more lighting and more co2 means more nutrient requirement and more maintenance

post a new pic of your tank

The black out phase may help, you could have the a bacterial bloom or the beginnings of green water, it may have been caused some sort of ammonia spike, do you use root tabs? this can be a culprit sometimes or maybe there was something else you did, you say you also moved the filter, are you absolutley sure the filter was fully cycled? this may be another cause, anyway hopefully the lights off period will help, normally you would totally black the tank out but thats up to you.

Id advise you to read the pinned article on the Estimative Index at the top of this section, you are basically running a highlight tank but some of your readings are a bit low, you need to increase your co2 level to around 30ppm running the airstones is counter productive, because they will also run what ever co2 you have in the water out of the water very quickly, people dont normally run airstones in planted tanks for this reason, you may run an airstone at night, your nitrate level is also a bit low at 5ppm, low nitrate levels can lead to bga, and you dont want bga, you also dont give a phosphate reading for your tank this is also important, you will have to invest in a phosphate kit if you dont own one allready.

What sort of fishload do you have in this tank? also i presume the coralife tube is specifically for plant growth?

You cant really have to many plants other than for practical reasons, space for fish to swim, will they grow to big etc, but because you have more plants you will need to feed them correctly or you may experience problems with algae.

Anyway i would say the lights off period will help, if the water is still cloudy after this 2 day period you may have to wait and see if it clears or do a total blackout of the tank.
