{"title":"Laguna","description":"\u003cp\u003eLaguna is Hagen's pond range — pumps, pressurised filters with built-in UV, fountain fittings, preformed ponds and, importantly for anyone who already owns the gear, a deep catalogue of genuine spare parts. Most of what is here is exactly that: impellers, shafts, quartz sleeves, UV lamps, foams, O-rings and clamps, listed by the model they fit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoosing a pump\u003c\/strong\u003e — the two families do different jobs. Fountain and statuary pumps move small volumes and are made for a spray or an ornament. Max-Flo pumps handle solids and are what a waterfall or a pressurised filter needs. When sizing, look at maximum head as well as litres per hour: the flow figure is measured with no lift, and it falls away as the water is pushed higher, so a pump run near its head limit gives a trickle rather than a fall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eChoosing a filter\u003c\/strong\u003e — the Pressure-Flo range is pressurised, which means it can sit buried to the rim beside the pond and still push water up to a waterfall. The model numbers refer to pond volume in litres and assume light stocking; with koi, or a pond in full afternoon sun, go up a size. An undersized filter is the usual reason a pond stays cloudy no matter how often it is cleaned.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eServicing\u003c\/strong\u003e — two things need doing every year and are behind most of the parts on this page: replace the UV lamp (output is largely spent after about 12 months, well before the lamp stops glowing) and clean or replace the quartz sleeve, since a scaled sleeve blocks the UV a new lamp is producing. Rinse filter foam in pond water rather than tap water — chlorine kills the bacteria that make the filter biological.\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/fish-filters-and-media\"\u003eFish Filters and Media\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/aquarium-pumps-accessories\"\u003eAquarium Pumps \u0026amp; Accessories\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/fish-water-care\"\u003eFish Water Care\u003c\/a\u003e\u003c\/li\u003e\n\u003cli\u003e\u003ca href=\"\/collections\/fish-supplies\"\u003eAll Fish \u0026amp; Aquatic Supplies\u003c\/a\u003e\u003c\/li\u003e\n\u003c\/ul\u003e","products":[],"url":"https:\/\/www.peekapaw.com.au\/collections\/laguna.oembed","provider":"PeekAPaw Pet Supplies","version":"1.0","type":"link"}
