i seem to have a problem with my water condition.i cant seem to get my water to be crystal clear like some bros do.

it looks like this : when the lights are off, the i can clearly see through the tank and it looks perfectly clear.however, when the lights are turned on, it's is obviously visible that there are minute particles floating around in the water.except for some which i notice to be tiny bubbles coming out of my reactor, plants bubbling like soda water and some white crawlies moving about the glass panels. besides that, it's those "i dont know what" particles which look white in colour to me visible to the naked eye(only when lights are turned on).

i've been doing some thinking and searching yet i couldnt come out with an explanation to it.

could it be the water hardness??? as i do have some coral chips in my canister since the last time i had calcium deficiency.

or could it be due to overdosing on NPK or micros???

well, i think i could fill out the need help template as well..

Substrate Used : river sand ~1-2mm dia.

How Thick is your base fert : ~2cm

How thick is your gravel : ~4-6cm

Liquid Fertilizers Used : PMDD

Frequency of fertilization : daily

Tank Temperature : 25-27 C

Type of Filter (overhead/internal/canister) : eheim 2213

Chemical Properties (Fill what you can)
Carbonate Hardness (KH): 9 dkH
Total Hardness (gH): dont know (value too high > 20 dkH)
pH : 7.2
NH4 (ppm):
NO2 (ppm):
NO3 (ppm): 40-80 ppm
PO4 (ppm):
Fe (ppm):

Chemical ferts dosing : per week

50% water change
3x5ppm NO3
3x0.5ppm PO4
4x3ppm K
estimate calculation of 4x0.22 Fe

Bioload (Your Fish and Plants)

5 amano shrimps

Plants :

micranthemum unbrosum (growing well but old leaves turning brown)
h.micranthemoides (growing well but slight BBA on some that didnt recover from Ca deficiency)
glossostigma (growing well)
blyxa japonica (growing very well)
e.tenellus (growing and spreading fast)
rotala indica/rotudifolia
(see some orange tinge and growing well)
rotala walichii (not so well but looks like recovering - alot of side shoots)
1 unknown (not too bad)

oh yeah, i forgot to add, for the past few days, i see some thread algae on the glass and i'm still battling minor spot algae on some glosso leaves and the glass panels which convinced me to invest on some test kits.

i've checked the fine filter wool making sure that there's no passage way for the water to flow right through....and hence, the condition improved by 70%...and i'm still having minute particles in the water column.

i shall try doubling the amoung of fine filter wool tonight

however, could it be due to the design of my canister?? eheim 2213....could the water flow be too strong for a 24"x12"x15"????

i've never had the problem with my 2028....

i just found out my KH, pH and NO3 readings today..

KH = 9dkH <---is it too hard??
pH = 7.2 <--- i still get a good reading of CO2 from the calculator
NO3 = 40-80 ppm <---*phew* :!: ...and my amano shrimps are fine

so could it be the KH ?? i'll lower it from 9 dKH to around 5 dKH by removing my coral chips in my canister and use Sodium Bicarbonate instead...(which i suppose what most bros have) and i dont think i need to buffer gH as my tap reading is more than 20 dKH which i guess is i right???

*my nitrate reading really gives me a shock. i guess my stock solution isnt that accurate after all since i did not use distilled water. however, water change is tomorrow, so i'll bear with it. Luckily my amano shrimps survived. in fact, my tap reading is already at ~10 ppm. so i guess i wont be needing to dose much of NO3 if i feed well.

How old is this tank?

You may want to lower the amount of nitrates in your tap water. Otherwise, I don't think any of the "problems" you are pointing at are causing the cloudy water. Does the water have a white haze to it?

If you are a real clear water fanatic, you may want to invest in a diatom filter which polishes water to the point that the fish seem suspended in air.

If your tap water is 20dKH, then why in the world are you using coral chips. Ditch them. I would be trying to _lower_ your KH, personally, to something between 3-8 degrees.

this tank is close to 2 months old....

infact, it's due to my stupidity and curiosity that the tank has too much nitrate. my tap water only reads 10ppm of nitrate.

well,like i said, the water is clear, not cloudy, hazy, or's clear...but the problem is that it has minute particles visible to the naked eye when the lights are turned on. i'm not really a clear water fanatic but as far as i can see from fish stores in my neighbourhood, their water seem to be very clear without minute particles in the water column which lead me to think that there's something wrong with my water quality.

and finally, it's also due to my curiosity that the coral chips are in my canister. i never had test kits before this and as a newbie, i read somewhere that says that a lack of calcium or magnesium will lead to distorted and curled leaves which was exactly what it looks like in the tank. so i added almost 400g of coral chips into the canister. i'll do a water change and lower it to around 3-5 as my tap water reads 2 degrees

btw, thanks for the advice
