Botanicare Porthole Cover | Fits 10, 20, 40, 70 & 115 Gallon Reservoir Lids

Botanicare Porthole Cover for Reservoir Lids Botanicare builds an access port into its reservoir lids so nutrients can go in without lifting the whole lid. This cover is the cap for that opening. One size fits every Botanicare lid in the 10, 20, 40, 70 and 115 gallon range, so a mixed set of tanks can share spares. A raised grip on top gives fingers something to hold, even with wet gloves on. Lift it out, pour in the nutrients or drop in a meter, then set it back in place. The cover measures about 7.3 x 5.5 x 1 in and weighs roughly 0.19 lb. Keeping the port closed matters more than it looks. Light reaching nutrient solution feeds algae, and an open hole lets in dust, leaves and the odd insect. It also slows evaporation from a warm tank in a busy grow room. Growers who run large reservoirs on a bench or under a table tend to keep a spare or two on hand. That way a cover knocked to the floor during a refill never leaves the tank open overnight. Feeding Through a Reservoir Lid Port A reservoir lid with a port turns daily checks into a quick job. Pull the cover, dip a pH or EC pen into the solution and read it without lifting the lid. Add nutrients and pH adjusters through the same opening, then stir with a long paddle. Topping off with fresh water goes the same way, straight from a hose or a watering can. The lid stays on, so pumps, chillers and plumbing through the bulkheads are left alone. Once the readings settle, press the cover back into the port until it sits flat. Rinse it with the rest of the gear between runs to keep salt crust off the rim. A clean rim gives a snug fit and keeps light out. Key Features Fits Five Lid Sizes: Covers the access port on 10 to 115 gallon Botanicare lids. Raised Grip: Easy to lift out, even with wet gloves.
