Brian - I won't say anything negative about BARACLEAR since I'm not overly familiar with its properties, mode-of-action nor cost-effectiveness.

However, I'm a little apprehensive of its use in fisheries management programs - particularly if a phytoplanton bloom is desired. The mfgr's promotions comment on tying up phosphates - which is exactly what most pond fertilization programs seek to provide for phytoplankton production. Therefore, the product's use would seem somewhat counterproductive for many fish-production situations - unless you're feeding the forage-base in some other manner.

Then again, BARACLEAR's overall effect may not be that much different from a conventional aluminum sulfate treatment (commonly used to clear muddy water). However, aluminum sulfate can cause a rapid pH shift (drop), sometimes to such degree that the fish cannot tolerate it. In some cases, quick lime is used to offset the pH shift caused by aluminum sulfate treatments. But, it can be a tricky proposition to apply the two compounds at the proper ratios (to cancel pH shift) - and you really need to know what you're doing to avoid fish problems.
