Best High PH plants?

I am happy that someone started this thread as I have the same problem.

8.5ph from the faucet after a 36 hr rest. A steady 8.0 ph in my 33g tank.
Add to this, the depth is 22" from the bottom of my light to the substrate. I'm using a t5 ho Current 78 watt light fixture. I think this is low to medium.

From the start I can consistently grow two plants; bronze wendtii and
Echinodorus barthi (red melon sword.) Anything else gets holes and black spots. I have a jajva fern on driftwood about mid tank which grows in volume greatly, but always gets full of black spots and holes.

I use liquid ferts from Seachem. When I use iron or nourish, my water clouds for several days.

I've read countless articles and have spoken with many people and nothing ever changes. Good luck trybry5

thats weird that your ph drops like that, do you have driftwood?

your sword and crypts are doing ok because it gets its nutrients from the substrate, other plants in your tank are probably looking for ferts in the water column. if they dont have N-P-K you will end up with deficiencies like that. which specific nutrients are youdosing? what other plants do you have? are you using co2?

the java fern may have black spots because thats how they reproduce. you may see plantlets grow from those black spots

oops sorry, wasnt paying attention. i see that you have driftwood
 
probably wouldnt be a bad idea for you to start your own thread so that everyone can focus on your tanks needs and also help out the op of this thread without confusion
 
timwag2001, I use potassium, trace, excel, nourish and iron from seachem. From Brightwell, I use multi nutrient with iron and iodine and nitrogen source and growth accelerant. I switch these two companies products.

I have tried so many plants, I've stopped keeping track. I have put so much money into all this. I've decided as soon as the liquid chemicals are gone, I'm going to dry ferts. PLEASe tell me exactly what to buy and from whom. I've looked at several sites and they all have different combos of dry ferts.

I am aware that java fern leaves at the tips turn black, but the entire leaf is spotted with black and then holes and then drops off.

Thanks for responding.

Less algae equals more nutrients for the plants for growth. And, i'm not sure that photosynthesis makes water alkaline (not sure though.). Plants tend to decrease the pH of the water, along with driftwood.

Depends on your definition of alkalinity.

Buffering capacity (ie. KH) in general? Or just high (>7) pH?

Certain plants will use bicarbonate as a carbon source, technically lowering the "alkalinity" of the water and thus the pH could lower depending on what acids are present. I do not know how significant the change is but I don't hear of any pH crashes happening because of this reason.

Then again as plants photosynthesize CO2 is being taken in, which I assume would cause pH to rise (become more "alkaline"). But its not a one way street and respiring plants will add CO2 back into the water. Not to mention there is an abundant supply of CO2 waiting to be added back into the water with any amount of surface agitation. In a non-injected tank I doubt CO2 levels fluctuate really at all (usually around 2-3 ppm). And in a CO2 injected tank I believe the most dramatic movement in terms of pH is down, not up.

I see no direct relationship between pH, plants, or algae without some outside source of meddling...but maybe I'm missing something here. To the OP: sorry if I'm dragging this offtopic.

i'm not familiar with brightwell, once you swith to dry ferts, life gets much easier in my opinion. i buy from aquariumfertilizer.com. you need potassium nitrate (kno3), mono potassium phosphate (kh2po4), and csm+b for trace. you can read about dosing here http://www.barrreport.com/showthread.php/2819-EI-light-for-those-less-techy-folks


the liquid ferts should have a number somewhere on the bottle that looks somthing like this 0-0-3 those numbers represent N-P-K (nitrogen, phosphate, and potassium) so if you pick up a bottle and it says 0-0-3 that means that 3% of that solution is potassium, and that is all, it has no other of the essential macro nutrients. it doesnt sound like anything has phosphate in it, am i right?
 
Tim, of all my bottles, the only mention of phosphates is in the Flourish "available phosphate (P2 05) = 0.01%" So that is a key fert? When I read the bottles they all claim to be a key ingredient....
 
thats not enough, seachem flourish is trace with minimal amounts of n-p-k. it is intended to be used with seachem nitrogen, phosphate and potassium. check out seachems website for flourish comprehensive, it'll say the same thing that i just said.

here is a pic of nutrient def's

are you having problems with green spot algae at all? it can be an indicator of low phosphate.


and yes its a key fert. n-p-k are called macro nutrients and trace minerals are micro nutrients
 
Anyways, I have water that varies from about 8.2 to 8.4 or so. Never had issues with any plants that I could directly attribute to pH.

Hygrophila species are good nitrate suckers and with decent light (not much) are pretty quick growers. I recommend wisteria (H. difformis) personally.

Thanks, I will look into getting some!
