It's nice being able to pinpoint what deficiencies your plants have and adjust the dry ferts to your needs. Its definitely more economical too.

That was one reason I did it finally. I read that a dirty filter can cause nitrates to overdose your plants with certain macrosI wonder if some of the problem you're having might be the dirty filter? a dirty filter doesn't flow as well as a clean one.Just an idea,since theoretically,the liquid ferts are just dry ferts and water.
thanks for the reminder on the filter.I usually clean mine while I'm doing water changes.
I took some time to evaluate what was in my dry macro\micri mix to my flourish and it does seem each had something the other didn't but flourish definitely had a large variety.Not to pick on a guy while he is having a problem but there are a number of things that do change besides the ferts, even when we don't think there are changes.
Some things that may/may not be giving trouble:
Filters get dirty. That slows flow so that CO2 is not moved around the tank as well. Also the can be hiding a ton of debris which is a ton of ammonia to be processed to nitrate. Filters don't clean the tank setup, they only hide it out of sight!
Lights are constantly aging. Tube lights that start out good may not be so good when a few months older. Plants grow and change their needs just as fish do. We can't just set up a schedule and expect it to stay the same long term. It is always changing.
So we also have to be aware and change as needed. Sorry about the trouble but then I don't find it unusual. In my tanks there are almost always some form of struggle going on. If the plants are not growing, that's trouble but when they do grow, some other plant may get shaded so I don't expect it to ever really reach and set and forget situation.
sorry I never responded to this.I switched from using flourish and flourish excel to PPS pro and excel 2 weeks ago. & Now my plants look terrible. Holes in leaves, brown edges. Since I have changed my cms+b to ei based and I am going to try that. I'm curious if you ran into similar problems? What were you using before and what dry dose method did you change to?

its 55 gallon highly planted. I honestly thought I was under dosing by the directions. I usually put one 1 liter cap a day or so. I was doing like 2 or 3 before the fish with no effects.this
flourish comp is IMO the most useless of all the liquid ferts
you are essentially paying for water w/bottled ferts
you are probably dosing a much greater amount with your dry ferts which is leading you to issues...
Well I was dosing about 2 to 3 i liter bottle capfuls every day or so before fish for a WHILE. Then when I added fish I started to pull back because I didnt want to get the fish sick or over fert since now there was fish waste. Im not sure honestly what went wrong here. Maybe it just took that long to rack up the over ferting but I barely EVERY did water changed when it was just plants and they were fine. I did about a 50+% water change before adding the fish and then have done weekly since. Except this week as I got busy yesterday so Ill have to do it tonight or tomorrow.yeah like i said you purchased standard dry ferts i am assuming (KNO3, K2SO4, KH2PO4, etc...) and probably dosed EI levels in your tank (a lot)
that would be like 50x more than you were dosing before with liquid ferts which would obviously make a difference...
you are saying you are dosing 'capfuls' of your dry ferts? what does this mean? did you make your own solution? if so are you sure you made it correctly? even with correct solution dosing EI levels you are still dosing MUCH more than you would be before with liquid fert regimen. messing up solution and dosing beyond those levels could be even larger issue...
IMO you should have just dosed dry... just take measurements of dry ferts and dump right in the tank (this is what i do)... generally coming from dosing very little you will want to do like 1/4 EI or just dose as you see fit. jumping right into EI is IMO never the way to go. calculating all this crap via your solution is just that much more complicated... easier to just throw 1/8 tsp of whatever in your tank every couple days IMO. want to dose less? just measure out a bit less when you dose. easy
company did not send you a 'bad mix of ferts' you just had no clue how much you were really dosing... If you cannot answer question of "how much ppm of nutrients are you dosing before vs after switching" then this needs to be answered to really understand what is going on here... as you can see from above poster liquid regimen provides very low ppm of all nutrients... EI will provide much much more than this... I too have seen problems with dosing too much dry ferts but when you scale back and realize you are dosing too much you can get good results for far less $$
basically for rule of thumb going forward if liquid ferts are working for you and you want to switch to dry ferts to save $$$ do NOT dose full EI levels... start off with much less. EI is FAR more potent vs liquid products... this would be a huge increase... people assume EI is comparable to liquid fert levels and run into problems frequently... this is not the case... EI is MUCH more potent
these are what you need to know for the solution you created... without that info you have NO IDEA how much of each nutrient is entering your tank... essentially dosing blindly...Hope this helps.

Its the densely planted 55. I was dosing 2 capfuls of dry ferts. they were 1 liter selzter bottle caps, I forget what that equaled though when measured but it was equivalent to the flourish cap so I used those dosage requirements after I worked up to it from doing the switch from flourish to dry. I started by using the direction on the bag of dry ferts, but I forget what that was. Everything I did was off the directions of the dry bag, even mixing it with water. This bag of dry ferts was not a bunch of them separated, they were already pre mixed and the bag just told you the mix of dry to water then suggested dosage. It was not one of the kits that has a bunch of jars.ok but i don't think you understand it is all about WHAT you were dosing and HOW MUCH... what solution is this..? how potent is it? understand that '2-3 capfuls' means nothing to me... again, you need to answer question of how much you were REALLY dosing vs size of your tank...
I don't even know what you are dosing when you say you are putting capfuls of solution in... what solution is this? how did you create it? are you sure of how strong it is / what dilution it is? was this ever calculated?
usually when people make solutions from dry ferts they calculate exactly how much ppm of nutrients they add to their tank size based on amount dosed... aka they could definitively say for 10ml of solution they are adding 5ppm N, 1ppm P, 2ppm K, etc... this is a finite ratio that must be known...
for instance a previous poster had those #s for liquid ferts you were using...
these are what you need to know for the solution you created... without that info you have NO IDEA how much of each nutrient is entering your tank... essentially dosing blindly...
i only recommend dry dosing because it is more simple to calculate... you can easily know these values and adjust... for instance you can easily calculate things like (this example is made up / not accurate):
if I add 1/8 tsp KNO3 to my 75 gallon tank i will be adding 1ppm K, 3ppm N...
when you make a solution you need to know how much nutrients you add per volume of liquid which is totally dependent on what you made the solution from in the first place.
