2 weird issues

First and weirdest issue: None of my fish ever get that big! In particular my SAEs and Bristlenose pleco....I have had both of these fish for a year or so now, and both are maybe 2 inches or so. They get fed every day. high quality flake and algae-wafers, nitrates are usually low, like 5 ppm or so, and they both live in a 46 gallon not over-stocked tank. My only thought is that our water has both high pH (~8) and is very hard as well...the tank they are in gets ferts sometimes and flourish excel

Second issue: my plants in another tank (20L) are growing very strangely. The new leaves are pale and very small compared to the old growth, the stems seem reluctant to put out roots. The tank gets fertilized with macros 2 times a week and micros once a week (flourish) It has DIY CO2 (2 bottles). pH is about 7.4 down from 8.2 out of tap. Lighting is approximately 3.4 WPG.

Any help or thoughts appreciated
Thanks!

Don't know about the first issue, but have you tried dosing EI for your 20L?

On the first issue PH doesn't really matter that much as long as it's stable
unless your trying to breed something as nearly any fish will adapt to there
environment.

The more important thing is KH (Carbonate hardness) which controls your
tanks buffering ability and determines if your PH yo-yo's out of control.
A spiking or plummeting PH will kill any fish. But that doesn't seem to be
the problem since nothing is dieing in droves.

Another thought is while you say your using a high-quality food do you
vary it at all? My community tanks gets several different types:

Ocean Nutrition Formula Two
Ocean Nutrition Spirulina Flakes
Baby Brine Shrimp or Flightless Fruit Flys (whatever I'm cultivating)
Aquadine Freshwater HiPro Duraflake
Fresh Vegitables (whatever we have in the kitchen)

I feed a different one every day and they have seemed to do much better
than with just one food.

Something is definitely wrong if you have that much light and C02 and
you still have a deficiency in your plants. I'd say it's between the fertz
and your C02 one of them is the culprit.

Variety of food is good but I cant see it being the problem. I fed my pleco regular algea wafers every day or every other other day for maybe 4 months and he got about 5-6in. Maybe you fed them to often and their matabalism got to fast? Just a wild guess.

Another reason could be that there growth was stunted b4 you bought them. This happens when they stay in a small tank for sometime while they are young. Some fish grow out of it while others will just stay small.

Well, that couldn't have been the case with the BNP, as I know the breeder, but could well have been the case with the SAE...I never really thought of that.

I guess I wasn't very specific with my dosing when describing my dosing, I basically follow EI for the 20L. My flourish is old, maybe this is the problem, for traces?
