Is trickle tower necesarry for my pond? Can't Post
I have a 1,700 gallon pond with 550 gallon filter chamber (Brushes, Japanese matts, heavy aeration on the matts)

Pump circulates water at 1900gph so turnover is a little over 1x per hr.

I was having problems with Nitrite (0.4ppm) so Japanese Matts were just installed 2 days ago. Nitrate readings as of that time were 10ppm

Current Water Parameters:
Ph = 8.5
Ammonia = 0
Nitrite = 0.1ppm (went down from 0.4)
Nitrate = 10ppm (same)


Do i need a trickle tower to improve my setup? Is the nitrate level ok? I read that the bio filter will take a few days/weeks to mature... will this lessen the nitrate level in the pond?

A trickle tower certainly wouldn't hurt, but what works well for your pond is really all that matters.
One of the advantages of a good TT is that much of the CO2 and Nitrogen waste by products are gassed off, which helps to improve water and also stabilize ph somewhat (CO2 is acidic).
The way I read it you just added the JMat, so I guess before you were just running brushes? If that is the case you are lucky that your numbers weren't a lot worse as brushes don't provide much in the way of biofiltration. Just solids removal.
A TT installed at this time would probably save you much of the new pond/filter problems you would otherwise face. All Nitrogeneous wastes (including raw ammonia and nitrite) are also gassed off somewhat by a TT, which means your biofilter load will be reduced while it matures.

Oh yeah, I forgot to mention.. the previous setup had a bio chamber aside from the brushes... (think Plastic PVC tubes, stones, rough sponges) and it only occupied around 1/4 of the total area occupied by the filter chambers.

I'm not so knowledgeable with the PH levels in my pond... is 8.5 ok for the fish? How do I go about reducing PH levels (aside from the TT) ?

Vipvip.

8.5 ph is on the harder side. what you want is to stabilized the ph.
and to prevent from PH crash is just put oyster shells in your last chamber. it works wonder.

7.4 to 7.6 ph level is ideal.
